  1. Module 2 Lesson 6 • Connect area diagrams and the distributive property to partial products of the standard algorithm without renaming.

  2. Common Core Standards 5.OA.2 Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.5.NBT.5 Fluently multiply multi-digit whole numbers using the standard algorithm.

  3. I can connect visual models and the distributive property to partial products of the standard algorithm without renaming. Learning Targets
