Ten worksheets have students match addition expressions to their correct sums, one worksheet per multiple of ten from 0+ through 90+. Each page lists ten expressions, such as 30+2 through 30+10, alongside a scrambled column of ten sums that students connect to the matching equation. The addend being added always ranges from 1 to 10, so the only variable across the set is the starting ten, which pushes the sums in order from 1 up through 100 by the final page. Every page repeats the same matching format, making the set usable as a self-paced drill or timed practice sheet.
