This lesson unit is intended to help you assess how well students are able to use “clues” about numbers including: factors, multiples, prime, composite, square, even, odd, etc. In particular, this unit aims to identify and help students who have difficulties with:
• Understanding the difference between primes and composites, or factors and multiples.
Common Core State Standards
This lesson involves a range of mathematical practices from the standards, with emphasis on:
1. Make sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively.
6. Attend to precision.
7. Look for and make use of structure.
This lesson asks students to select and apply mathematical content from across the grades, including the content standards:
4-OA: Use the four operations with whole numbers to solve problems. 4-OA: Gain familiarity with factors and multiples.
5-NBT: Understand the place value system.
6-NS: Compute fluently with multi-digit numbers and find common factors and multiples.
