Addition with Ocean Life — Kindergarten

Some rows here are add-and-total, some are find-the-part. In the first kind the child counts a group of fish, crabs and an octopus, reads a number, and writes how many in all; in the second the total is given with one part shown, and the child finds the part that fills the gap — the same thinking as making ten. Mixing the two keeps the child reading each row rather than repeating one move, and every amount stays small enough to check by counting.

Making a total from its parts and adding parts into a total are the same relationship seen from two directions. Kindergartners who practise both with the same sea creatures build the make-ten and part-whole habits later written arithmetic leans on, and because the amounts stay small, every answer is still something the child can check by counting the pictures.

Children who like ocean life enjoy the change of pace from row to row, and it works well for a small group ready to think in more than one direction. When the numbers feel easy, count a fresh group in addition with pets, or try addition with thanksgiving.
