Addition with Classroom Objects — Kindergarten

Adding and part-finding are braided together down this page so the same classroom objects get used two ways. One row hands the child a group of pencils, books and a globe and a number to fold in for a total; the next hands over a whole with one part shown and asks for the piece that completes it, the way making ten works. Travelling between the two keeps both ideas warm at once — joining amounts and pulling a number apart into its pieces — and the small totals mean a kindergartner can always fall back on counting the pictures to be sure.

A child who can both add two amounts and find the part hiding inside a total is seeing numbers as things that come apart and go back together. That part-and-whole understanding — decomposing a small number into its pieces — is core kindergarten work, and mixing it with plain adding of classroom objects keeps it grounded in counting rather than in remembered facts.

Children who like classroom objects 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 clothes, or try addition with farm animals.
