Number Bonds to 10: Part-Part-Whole Practice

This Kindergarten number bonds worksheet shows six part-part-whole bonds that all make 10. Each bond is a little diagram: the whole, 10, connected to its two parts — except that in every bond one circle has been left blank. The child reads the numbers that are given, works out what is missing, and writes it into the dashed circle to complete the bond. Six bonds, six missing pieces, one big idea.

Knowing the pairs that make ten — 6 and 4, 7 and 3, 8 and 2 — is one of the most valuable pieces of number knowledge a young mathematician can own. The bond diagram makes the relationship visible: numbers are not just symbols in a row but wholes that break into parts and parts that come back together. Children who own these facts decompose numbers effortlessly later on, which is exactly what mental strategies like making ten are built from.
