First graders add three numbers when one addend is zero or a repeated doubles pair, such as 0+4+5 or 3+3+3. Students trace six words including make, ten, pair, then, equal, and find. Four fill-in sums and three true-false items reinforce the idea that zero does not change the total and that doubles make adding quick and easy for young Grade 1 math learners everywhere today.
