Early algebra is just arithmetic with a mystery number. These worksheets start with simple missing-number equations (X + 3 = 8) in grade 1 and build to multiplication and division equations, two-step equations, and grade 5 equations with variables on both sides — always with whole-number answers.
Every worksheet includes a work box for each problem.
