I have started a reward system for behavior during school.  A very simple one.  WHoever gets the most stars during the week gets a treat on Saturday. 

Three stars = you worked well, quietly, and did not disturb anyone else. 

Two stars  = you needed to be redirected, you distracted someone, you didn't focus on your work.

One star  =  you did your work, but not very well.

No stars = you didn't finish your work on time, you played, you distracted...

So far, no one has recieved less than 2 stars a day.  But boy when I tell them "Do I need to take a star away?" they straighten up and work well!  This is based on behavior only.  It is hard sometimes to get them to focus on their work, especially when little sister is trying to play with them. 

This week, they both got the sme number of stars - 14.  They worked REALLY well.  I was so proud of them.  Their treat was a root beer float.  Both of them earned it this week....not sure what next weeks will be yet.  And I'm not telling them what it is either, not until Saturday morning.  This way, no one can say "Oh, I don't want that".   Or say they wanted something else.

Blessings,

Hope
