Common Questions for this 3rd Grade Math Review

Q: What is “Making 100”?
A: Clue 3 focuses on finding the missing number to make a total of 100 (e.g., 65 + __ = 100). This is a critical mental math skill that helps build number sense and fluency.

Q: Is this good for Test Prep?
A: Yes! Because it covers a mix of strands (Measurement, Number Sense, Operations, Fractions), it acts as a fantastic Spiral Review before spring standardized testing begins.

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.
