Common Questions for this 3rd Grade Math Review

Q: What is “Expanded Form”?
A: Clue 1 requires students to take a number written in expanded form (e.g., 2000 + 400 + 50 + 6) and convert it to standard form. This is a key Place Value skill for 3rd grade.

Q: Is Clue 5 difficult?
A: Clue 5 involves finding the missing number in an equation (e.g., 5 + __ = 12). This promotes Algebraic Thinking. If your students struggle, providing them with counters or number lines helps!

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.
