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

Scientists are creating a material that may
replace damaged cartilage in human joints.
This hydrogel can stretch to 21 times its
original length. If a strip of hydrogel measures
3.2 cm, what would its length be when
stretched to capacity?
