:help: I need to design hands-on activities for children ages 3-4 using everyday materials to teach specific math concepts. Does anyone have any suggestions for teaching one-to-one correspondence, classification, measurement, comparing, ordering, serration, shape, parts, and patterning. Our theme is turtles so I am trying to create these math concepts around turtles. I could also use any suggestions on books, songs, or fingerplays relating to these math concepts. Thanks a bunch.
