Dec. 5, 2009 Magnetic Math Sentences
Nov. 10, 2009 "Are we There Yet?" Math
M knew that we had passed the McDonalds at Hamonasett, because he'd finished dinner. He knew that was the half way point to MomMom and DadDad's house, and he knew that it took 3 1/2 hours to get there from our house (ignoring the variables Daddy mentioned like rush hour traffic and accidents that M always does ignore and DH always does mention.) And I knew that M knew all that stuff, because DH and I had told it to him over and over again. But he really surprised me when he announced that we had 1 3/4 hours left to go as we passed the gas tanks at the Hamonasett rest stop, about to merge into traffic on rt 95 South.
So I asked him how he knew that.
"Well, we are half way there, and the trip is 3 and 1/2 hours, so we must have half of that left to go. 3 is an odd number, so half of 3 is half of 2 plus one half, so I took that part off of the 3 and one half, then I divided thehalf that was left in half, which is a quarter, and I stuck it back on the one and one half from the 3, and that gave me two piles of 1 and 3/4." He said.
It sounds like the hours were a log he was sawing and moving pieces around visually. It's so fun to find out how he thinks! |

Oct. 30, 2009 More numberbonds

We still haven't gone back to worksheets yet: M is playful and engaged with the manipulatives, and not frustrated with himself. There doesn't seem to be such pressure for him to write things the right way the first time if he's finding patterns, and learning vocabulary by talking about his rod trains. We need to practice forming the numberals in handwriting time a bit before getting back to written work - I'm looking forward to written work, a chance to do the dishes, or work with B, or read to K for 15 min or so... |

Sep. 28, 2009 Pre Breakfast Math, with M
K did only get me up twice last night, but I was still slug a bed at 7AM. I heard DH herding children, and M plaintively call, "Are all these cool library books for me? But who will read them to me?" I knew DH was brewing coffee, so once he'd brought me a cup, I told M I'd read to him, in bed, while K nursed. We enjoyed An Octopus is Amazing by Patricia Lauber. Then ate oat meal, even though M was begging for the math books. We for-stayed him by asking him to tell us what he'd learned about math lately. He told DH that 3 squared is 9. Then he checked to make sure that 9 was one less than 10, and asked if 10 squared was one less than 9 squared. He was disappointed to hear that 9 squared was 19 less than 10 squared, but I promised to pull out the cuisenare rods to show him why this morning. Mean while we have read The Mission of Addition, and the Action of Subtraction, both by Brian P. Cleary. Both have funny illustrations, but keep negative numbers a deep secret, and don't play with zero much. But the funny illustrations are very funny indeed! So, the boys have finished their chores, I have done a good chunk of M's math, but I'm still wearing pajamas. I guess if M understands squaring, but can't count conventionally yet, he gets some of his a-synchrony honestly! |

Sep. 23, 2009 It's Me Oh Lord...
Standing in the need of prayer, and grace. Yesterday I disciplined M in anger, had to apologize to him, my husband, the Lord. Today I'm anoyed at myself and trying to remember that my standing with God depends on the blood of Christ, not my sincerety.
Everyone is sick accept DH who spent his 15 min break getting us more tissues and TP. We are now running out of Tylenol elixer, but the boys can't get another dose until after nap time anyway.
Last night K only got me up twice, but I didn't sleep in between times. B took to showers so he could un-stuff his nose, and M transfered himself to our bed at 5 AM. (I switched to his bed.)
This morning we all slept in until 8AM, accept K and DH, who ate cheerios and raisens together. The burning question of the day was "Will we Homeschool?" Even K babbled it to me, minus the consonants. No. But we did do laundry, tidy up the floors, dishes, and I played number bonds with M, who switched over to squares, and trying to lay down one hundred, then count them to make sure he's gotten it right. You go M, you needed some painless nominclature practice!

K just tried counting squares, minus the consonants.

Sep. 10, 2009 Hop Scotching the Number-Line
|
M has been proud of his ability to use a number line to estimate sums, but differences were too difficult, and getting “wrong answers,” on his work sheets were very trying for him.
We switched venues by drawing a long number-line on the sidewalk. (This also gave little sister a chance to run around outside!) M practiced adding and subtracting numbers, hopping by twos, and such things. I had to draw a new one today, because Tuesdays has gotten so scuffed. We included negative numbers of course, that makes M feel so grown up.

He solved one of his on-going irritations: he figured out why he often made the “off by one.” mistake. When he was adding a number to another on the number line, he began counting with that first step onto number-line, not the first step in the direction he was going. He also wasn't counting zero as a place on the number-line. When I told him that computers often made that mistake too, he laughed and said, “oh, if the computers make it all the time, of course I make it all the time.”

M has a wonderful grasp of doubling, in fact, the way he used to count was, “one, two, one and two, two and two, two and two and one, Mommy, I can't count that high.” Then he switched to, “One, two, three, two and two, five, three and three, seven, four and four...” Just as I thought he'd tired excessively of number-line hopping, he announced that he did know some differences! If he subtracted 3 from “three and three” he'd land on three. He patiently stepped it out, and was delighted to be correct. He also did it with ten to five and four to two.

Sometimes I think I am teaching calmness as much as I'm teaching mathematics: but then I don't set him a good example of anti-perfectionism by being annoyed that he is not perfectly relaxed!

Sep. 9, 2009 Some Learning has been going on, but is it what I meant to teach?
This morning, K grabbed the paper towel I was wiping the white board with at breakfast, spilled her milk on herself, and then wiped it up. Umm, she did learn about wiping up?
Why did I need the white board at breakfast?
B is up to dividing fractions. The boy has got to know why, because, "Mom, it's not satisfying to follow a procedure when I don't understand it. It's not comfortable."
I tried explaining yesterday about inverses. The light came on, then faded. So I turned to the LivingMathForum Yahoo!group. Already this morning my post has gotten some helpful replies.
We also found some fun videos: I can divide (to the tune of "I will Survive") good for remembering the procedure. Math Playground has a snippet where they show that sometimes you can just divide directly, and Welcometochrisworld has a clever way to explain why invert and multiply works; if you've already had algebra and understand negative exponents.
I tried again this morning to explain why it works (this was where the white board cloth met the accidentally on purpose milk spill):
a/b / c/d is equal to (a/b / c/d) x d/c / d/c (the identity) then that would equal (a/b x d/c) / ( d/c x c/d) and the macro denominator cancels, leaving the good old: a/b / c/d = a/b x d/c. The light came on, then faded.
But DH (of course, he has all the luck) really made a breakthrough, when he started asking how many dotted half notes could fit into a 4/4 measure of music! Our B is a real aural/oral learner. Trust DH to think of music as a tie in!
I think I'm going to do some sidewalk math today with B and divide up the cement rectangles, as Maria suggested at Natural Math. I should think of a way to use music too.
Yesterday we played Miquon games on a numberline on the sidewalk, to help M with subtraction. He doesn't mind having to try again so much if he's playing a game with me, but having to erase something on a work sheet? Oh Boy.
K just climbed on my lap, she has gotten a stocking cap on her head, one shoe on and off by herself, and I did check her ankles, no hair elastics there: lots of learning going on, but she hasn't gotten to consequences yet. Necessary, but so messy!

Aug. 2, 2009 Fruitful Digressions
Jimmie and Sprite made Platonic Solids this week. They were a mobile until the cats got at them - the fate of all mobiles of cat owners? Ours gather dust but I still leave them there - same decorating phenomena as my kitchen curtains. I wonder if I would decorate diligently if my landlord allowed pets?
Do you sometimes spend a week on one lesson's improvisations? Do you enjoy it? Does it frustrate your sense of linearity? How about your kids, are they linear? Do math lessons in particular take side roads? Mine do more than other subjects.
I was thinking this year that the only tasks that got done smoothly in B's homeschool were the ones on his check off chart. So I was thinking that I need to add such things as "20 lessons from the art book" or "write 10 e-mails to your friend in Arizona." He thought that was a good idea, I asked how we would handle changes, if something fantastic came up, he suggested a 2 week heads up time to get used to the idea!
K just wants the world to know that she does not plan on sleeping again, ever. It is a waste of precious time. It doesn't matter what books Mommy reads from the library, even if the ideas in them work deceptively for a week or two.
My girl may get me to give up coffee. (She isn't weaned all the way)
M just wants to know when he gets to play with his new school books (when I finish last year's paperwork and my foot works...)
My boys are going to get me organized I guess.

Jul. 23, 2009 Math Sentences with M
M and I have not been doing any formal school in a while, but he has been announcing math facts so I know that he is thinking about things. Like, "If you add an odd number and an odd number, and another odd number, it will be an odd number, wait, no, yeah, that's right..."
Today he bounced on my futon in the living room, where I am usually to be found, elevating my foot, and told me that, "If you had three groups of four, and took two away, then you would have ten."
I got out a paper, wrote his sentence, then showed him how to use the x for "groups of" and + for "and," and = for is. He tried dictating a few more sentences, then ran off down the hallway.
Sometimes when I worked at the Community College of Lake County, in Illinois, our math phobic students would relax when we showed them how the grammar of a sentence in an word problem related to a math sentence. Especially if you looked at the last sentence where the question was, and let the subject of the sentence be your X. I wish I knew where that technique came from, there was a hand out or something, it was the first time I'd ever seen that sort of grammar/symbol correspondence, and it always made our English major students relax. |

Jun. 5, 2009 Addition Methods
I have to look up in B's old portfolio how B used to do arithmetic when he was still getting comfortable with which numeral what which. I think he used to use counting, being my ears boy. But M surprised me yesterday when he showed me how he has been calculating his addition in the first Miquon book. He likes his rod track number line, because he can look up the numerals and remember where they come in the sequence. I though he was looking them up, then using Cuisenare rods to figure the addition. Actually, he was looking up the numerals, placing a finger on each of the addends, then eyeballing the sum on his rod track. It works well for him with small numbers, but when he has a large sum, he can get off in his estimates. I'm not really surprised, M has quite the eye.
This is the boy who asked me last year how exactly did you know how many things there are? I replied, "you say the name of the numbers in order as you sort each thing you are counting. The last number name you say as you finish sorting is how many things you have all together."
"Oh, that's how you do it." he replied.
I never expected to have to explain counting explicitly, I just figured everyone picked it up by example. M keeps surprising me.

Jan. 3, 2009 Great post over at One Vhild Policy Homeschool
Dec. 29, 2008 Cuisenart Rod Games for Pre-Schoolers
A few years ago, a post on the Miquon-Key to math group led me to a link forThe Cuisenaire Activity and Exploration Book
Miranda Hughes just re-posted it today so you can get a copy of it and the cards at her website.
This morning M and I agreed to do simple school while B finished his chores, so that M could quickly go play with his new Christmas Legos. After memory verses, and spelling dictation from SWR, I dug around in the file box of stuff the boys need me to do with them daily and found the zip lock bag of Cuisenaire Rod Activities for pre-Miquon kids I picked the page of 2-layer Rectangles. M liked it so much he kept playing even with those Legos waiting for him!
He especially liked how the "rod trains" of the two rectangles (say 3 orange 10cm rods and 10 green 3cm rods) would always come out the same length. It was like magic. M was charmed. I was charmed. What a lovely morning.
(I have two other file boxes in the kitchen, the art stuff box to go with the Barry Stebbings books, and the history/geography box for Story of the World The lockable lids let us keep them on the floor without worrying that K will get into them. I started this system when M was the baby, but I think I saw it first in a Practical Homeschooling article.) The daily-stuff-with-mom-box reminds me of what I need to do, but I also have a list on the back of the little white board. B has a box he keeps in the living room under his desk with his independent work stuff in it, he brings it into the kitchen when it's his turn to work with me.
Good housekeeping leads to cheerful improvisation. Now if only I can learn good housekeeping in other parts of my life... |

Have I mentioned before how much I am enjoying the Living Math Forum? Today I felt like we really have been reading those e-mail updates and benefiting from them.
Yesterday M finished the page 20 activity in Now I Know My 1,2,3's Count and Match and Add with Me! And I was again thankful that I kept good notes from B's kindergarten, because I was scrambling to find a good activity for M to do. I was digging in the big tub for a game or book, and found a little battered paper packet of cards. Ah, the pattern cards from
Peparing Young Children for Math, a book of games Claudia Zaslavsky
Schocken Books 1979
The last time I made those was in an early (and disastrous) co-op class. The class was a success, I was a disaster. But that's a story for another time.
My actual point was that the notes were on my hard drive and I could find them. M wanted to make his own pattern cards, so we picked colors from the card stock stash, printed the card templates, and the box template, then he spent B's spelling dictation/other lesson recitation time rolling out die cuts with the new Sizzits Sidekick early Christmas present. He will use the little stars and snowflakes to make his number patterns on his cards (the cards are like dominoes, only with numerals as well, to cement the numeral/counting connection, and to see how many patterns you can make with a number of things). Originally I searched out small stickers, but this time we will use the die cuts and a glue stick.
If anyone does want to make the cards and box, be aware the box is just a hair too tight: print and decorate the cards first, then fold the box around them. doublesided tape works great, glue stick does too.
In the Zaslavsky book, you write the numerals on half a 3x5 card, then make the patterns with little stickers or stamps. I had found a business card kit and printed the cards on that. Today I printed the numerals and cutting lines on cardstock and cut them on my paper trimmer.
Games to play with Pattern Cards:
Lay Down: This is an “Uno” esk game. Shuffle the cards, deal out 5 per player (with more players you run out of cards, improvise), put the left overs upside down, tum over the top card. If you have a card with a common number with the top card, you can lay it down. If you do not, you can draw one. Numerals can march patterns. The next player plays off the card the first player played. The first player to run out of cards wins.
Pairs: Like “Old Maid” Divide the deck among players. Lay down matches. Numerals can match patterns. Pick cards from each others hand until all matches are laid down. There will be one extra card. The player with the most pairs wins.
Train: Like Dominoes. Deal 5 cards out to players. Leave the rest upside down. Lay down the top card to start with. The youngest player puts a match from his card next to the top card. The next player can put a match on the last card, or the other side of the first card. Doubles can be laid perpendicularly, and both sides can be played on. If a player has no matches in his hand, he may chose the next card form the left overs. The first person to run out of cards wins.
I feel so gratified: we had a creative morning on a day I didn't know we would be pulling out the craft supplies, spelling happened anyway, the baby only catnapped, and I didn't yell at anyone!

Jun. 13, 2008 Thoughtful Math Discussion Forum
http://groups.yahoo.com/group/LivingMathForum
I've been enjoying this forum quiet a bit. Ever since I tutered math and chemistry at the college of Lake County in Illinois, I've been curious about how people learn math. Actually, I've been curious about that since I was a 6th grader hoping I'd be recommended for pre algebra so I could enter the calculus sequence in my school, even though I often made calculational errors, and had messy handwriting. My teacher gave me a semester to prove myself, and did let me take the more challenging class, and eventually let me skip a semester of college, and saved me time and money, and also to enjoy my school more. I had a weird habit of getting good grades in "difficult" math classes, and poor grades in "easy" ones. I loaf off when I'm bored, conceptual math is more fun than computational algorythms, and I remember things better when I know the why as well as the how. This was also my first introduction to John Holt, my mother had me read his book about children and math. I remember his take on gender math differences: boys are often told "oh the silly mistakes you make, you are so smart, if only you'd line up your columns so you wouldn't get confused!" and hear the you are so smart part. I was messy.
At Lake county I got to work with many newly arrived Eastern Europeans. They were my favorites, though a tuturing session could feel like a polite wrestling match. This seemed to be their method:Test everything, track down every theorem, don't accept an answer without a proof, sometimes two proofs...then thank your tutor profusely. They made my brain hurt, but it was a good hurt. I've been interested to read that Russian culture puts mathematics on a level of beauty with other cultural things, as well as the belief that everyone suffers, so what, things don't have to be fun, work hard. It reminds me of my friend S, who was the valedictorian of my college class. He always brushed aside compliments on his intelligence to say, "I'm a hard worker." If you take on math as something you work hard at, you will learn it. If you think there are math people and non-math people, you may not work hard at it.
There surely are folks for whom math is harder to learn, but the hard working attitude will do more for them than saying "oh well, girls aren't good at math." My other favorite group of people to tutor were the ladies finishing up their nursing degrees, after several decades of raising a family. They had been told in the '60's that girls weren't good at math, but they needed algebra to continue their degree.
There needs to be joy! Who learns to read and keeps reading if they don't get read fun things - magazines about their interests, good stories, living books? Math should be joyful. Let the kids play with word problems, look at sunflower seed pattern in the flower, think about fractals as well as learn the multiplication table so they don't HAVE to have a calculator. Math shows the beauty of God's creation, in order, in chaos, in proportion, in usefulness, in games, in strategy...
Anyway, the forum is fun.

May. 16, 2008 Bathtime Algebra
M picked out lots of toys for his bath last night. K was asleep and B was at Grandma's for Latin night. Two of the "toys" were an old decorative Buzz Lightyear shampoo top, and an empty dish detergent bottle (my kids play with the recycling before it actually makes it to the blue bins). M filled the detergent bottle completely, placed the Buzz head on top tightly, then inverted it.
"Momma, see the bubble in the bottle? That's how much water it would take to fill the Buzz Head."
DH and B arrived home at that moment, I had them come into the bathroom to hear M's brilliance, K woke up hungry, and we went on with bedtime. |
