Illinois State Assessments · IAR Math
Build Illinois mathematics readiness with five focused 10-question practice sets covering number, algebra, geometry, measurement, data, probability, and problem solving.
This Illinois IAR Math Practice Test page provides five short practice sets with 10 original multiple-choice questions each. The sets cover number and operations, expressions and equations, geometry and measurement, data and probability, and integrated multi-step problem solving.
The Illinois State Board of Education describes IAR mathematics as an assessment for Grades 3–8 that requires students to reason about quantities and relationships in real-world situations. These supplemental sets practice computation, fractions and decimals, algebraic thinking, geometry, measurement, statistics, probability, and mathematical reasoning.
Complete one 10-question set at a time. Show your work, check units and labels, then review the explanation after each response.
This is supplemental State Test Practice, State Assessment Practice, and Standardized Test Practice. It does not replace current Illinois State Board of Education guidance, official materials, accommodations, tool policies, or testing procedures.
