I found a clipart image of a tree outline on google and printed it up a few times on the computer. I wrote a number on the trunk and the kids used Q-tips to paint on either acorns (brown paint)or apples (red paint). We ended up turning them into a little book.
These math grids are from Teach Mama and they have been so much fun. Lou is counting "8, 9, 10" and "1,2,4,6" I think he's getting close to getting it right. All we do when we play is to roll the large dice and place that many markers on our grids. We play until everyone fills their board. I laminated ours so they will last all season. This simple game is a favorite!
