3rd Grade STAAR Math Practice Test Questions

Try these 10 free math review questions, then use the worked answers to check your reasoning. This is an independent Effortless Math practice set, not an official STAAR test, full-length simulation or prediction of your child’s score. Some questions extend beyond basic Grade 3 skills; use them to spot topics that need explanation rather than as a pass/fail test.

Have paper ready. Complete a few questions at a time, write the calculation or draw a model, and check the answers afterward. If a question is unfamiliar, review the skill together before trying a similar problem.
