This is a comprehensive review that can take anywhere from 30 minutes to 2+ hours, depending on your students’ skill level. We recommend pacing it by one clue at a time.
Q: Is converting Mixed Numbers covered?
A: Yes! Clue 3 focuses specifically on converting Mixed Numbers to Improper Fractions (Standard 4.NF.B.3). This is often a challenging concept for 4th graders, and this mystery provides excellent visual practice.
Q: Why “Numbers Ending in Zeroes”?
A: Clues 4 and 5 focus on dividing and multiplying numbers with zeroes (e.g., 400 ÷ 2). This reinforces Place Value understanding and mental math strategies (Standard 4.NBT.B.5 and 4.NBT.B.6).
Q: How does differentiation work with these?
A: That’s our secret weapon! Many of our stories are available for other grades, so you can “clue swap” with the 2-6 grade packs. We even have a blog post explaining how: learn how to differentiate here.
