MF.NS.4 Challenge MF-004-A12-V03

Use commutative, associative, and distributive structure to rewrite and simplify numerical expressions efficiently.

Check rewrite validity and use a specified target structure

Problem

For \(25~\times~16\), Rewrite A is \(25~\times~(10~+~6)\), and Rewrite B is \((25~\times~8)~\times~2\). Identify all valid rewrites. Use Rewrite B, which creates \(200\) first, to find the product.

Side-by-side comparison of the original expression 25 × 16 with Rewrite A, 25 × (10 + 6), and Rewrite B, (25 × 8) × 2. Each rewrite card includes blank check boxes for same value and easier to use. Open full size
