I use this to count by 2's, and 4's. The kids get to make all the creatures and then figure out how many feet are in the mitten!! They LOVE this :) Plus it is great for them to take home and retell the story!!
This is a great one to introduce the shapes. I have used a large piece of yarn that is tied together - 3 children hold it to make the triangle and then more children join in as the shape changes! It is very visual and they like helping make more sides!
This one I use to teach counting by 2's and 4's also! The kids then make a house and draw the feet in their house....They have to write the number sentence to go with it.
I can't wait to see some of the math books you are using!!! I've added links to Amazon for the books....these are just a few that I use!!!
