Give your fourth-grade students a complete Oregon OSAS Math review path with ten original tests built for confident progress.

This 10-test collection was created for teachers, parents, tutors, and homeschool families who want OSAS review that helps students grow through repeated practice, clear feedback, and thoughtful math models. It includes 10 full-length OSAS Grade 4 Math practice tests with completely original questions, student-friendly formatting, detailed answer support, and item-level standard alignment. Every question is 100% aligned to current Oregon Grade 4 Math standards, and every single item includes its own unique standard code.

Students practice essential Grade 4 skills: place value, operations, multiplicative comparison, factors and multiples, fractions, decimals, measurement, data, geometry, angles, visual models, and multi-step problem solving. The result is a print-and-go resource that builds accuracy, stamina, and confidence while giving educators practical information about what to reteach next.
