Free printable addition word problems with pictures, number bonds, bar models, and number lines. The unknown moves around — the total, the part added, or the starting amount — so kids have to read each story. Every worksheet is a one-click PDF with an answer key. Choose a grade below.
These free addition word problem worksheets mix the kinds of addition stories kids actually meet: adding to a group, putting two groups together, finding how many were added (5 + ? = 9), finding the starting amount (? + 3 = 8), and, in grade 2, comparing and two-step problems. Kindergarten stays within 10 with countable pictures; grade 1 works within 20; grade 2 works within 100 with bar models and number bonds.
