Hand a six-year-old two more crayons and ask how many there are now. Many children will count the whole pile again from one. This 1st grade adding 2 worksheet trains a faster move: start from the bigger number and count on two steps. Fifteen sums of vertical addition sit in colored boxes. They run from 3 + 2 in the top corner to 2 + 1 at the very end. The 2 sometimes sits below, as in 7 + 2, and sometimes on top, as in 2 + 9. Two of the sums go one step past ten and land on 11, so the page stretches a little beyond the facts to 10. A second page gives the answer key.
