# Clip 14/21: Standard 7: Look for & Make Use of Structure Using Decimals Part 2D

## Overview

*Mathematically proficient students look closely to discern a pattern or structure….They also can step back for an overview and shift perspective.*

Erika Isomura’s 5th-grade students continue to work in pairs to classify, sort, and glue down decimal representations in numerical order. Erika circulates around the classroom, engaging students in sharing their thinking. She says to one pair “This could be our prototype. This is our test run. We're kind of working on it, thinking. After we have some new ideas and maybe we have some better understanding of what we're doing, we can always come back into it. Okay?” This clip also relates to standard 3 (construct viable arguments & critique the reasoning of others) and standard 6 (attend to precision).
