We had such fun today counting the rings on felled trees in the woods. Some were too old to count but we counted till 10 and compared the rings with the tree shakers we had made. We also looked for circles anywhere we could find them in nature. There were circles on tree trunks (knots), there were circles on gopher holes and circles in the silo. Even the snout of Dottie the Pig was a circle! Nature, shapes and counting-education takes place out of doors!
