Common Questions for this 4th Grade Math Review
Q: Is Elapsed Time covered?
A: Yes! Clue 4 focuses specifically on Calculating Elapsed Time (Standard 4.MD.A.2). This is notoriously one of the most difficult concepts for 4th graders, so this mystery provides excellent, engaging practice.
Q: Do students need to simplify fractions?
A: Clue 1 involves Adding Fractions with Like Denominators, and students will need to reduce/simplify some of their answers. This is a great way to challenge students who are ready to move beyond basic addition.
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.
