I've been stressing over math, especially since I have taken 7yo dd back so far in lessons, with a long leisurely review of addition to 9, and now a long  leisurely review of subtraction to 9. All of the subtraction problems are getting little illustrations next to them, where dd draws 6 lines and scribbles out 3 of them to figure out 6 - 3. And I wondered if we'd ever get "there" ("there" is a magical place where something suddenly makes sense and seems easy). I assigned 3 pages of math, and figured she could finish it in 15mins if she just stayed on task and did it. Anyhow, half way through she says, "this is sooo easy! Look, 5 - 2 is 3 because 3 + 2 is 5." And the angels sang. The 3 pages took her 20 minutes, but I pointed out that she did sit there and dork around quite a bit (as evidenced by all the 4s and hs drawn around the page, because she discovered that 4s and hs were a lot alike. And also evidenced by the carefully written Times New Roman style numbers, with the little lines drawn at all the edges.) She decided that she probably dorked around for...oh, say...about 2 minutes, and then she computed in her head that it really only took her 18 minutes to complete because she dorked around for 2 of those 20 minutes, and 20-2 is 18. And its great to see the practical application of subtraction skills when you'd like to figure out how long you work and how long you waste time;)
