Math Mysteries

Grades 2–5

In our survey of 1,200+ IM® educators, teachers shared a common need: review that builds assessment readiness and keeps students engaged.

Our Math Mysteries deliver both.

Math Mysteries turn end-of-unit review into short, detective-style problem sequences aligned to Illustrative Math unit content. Students solve assessment-style math tasks to uncover clues and solve the case, without introducing new content or replacing instruction.

Teachers get print-and-go resources that align perfectly to IM units. No prep, no compromises.
Students stay engaged from the first clue all the way to the final answer.
Every mystery comes fully loaded for the perfect review:
