Know My Worth

Know My Worth is a Grade 5 decimal game that combines decimal operations with comparison. Students build decimal numbers from numbered chips, roll to determine whether they will add or subtract, calculate two results, and then compare the values using <, >, or =. The game asks students to keep track of both computation and place-value magnitude in the same turn.

Use it for partner or small-group review after students have learned to add and subtract decimals. Ask students to justify the comparison symbol by referring to place value rather than relying only on the final written answers.
