Can I say a number by its name, and can you write it for me? Working in small groups or with the whole class, give your kindergartners a piece of 1-inch graph paper and have them write numbers 0 to 10 and 11 to 20. Next, pass out blank graph paper. In random order, speak a number from 0 to 10 and ask pupils to write it down. Select several different numbers in the 0 to 10 range, and eventually move into the 11 to 20 range. The goal is for young mathematicians to associate the symbol they are writing with the word that is spoken.
