# Clip 9/11: Lesson - Part 7

## Overview

Here Tracy walks around the room and ask students whether the question made sense for them. Students were unsure how to take the phrase "How much more does the sparkle apple pen cost?" and turn it into an operation.

## Teacher Commentary

In this portion, students have access to manipulatives to revisit this problem. Several students took out money, and some students took out base 10 blocks. I gave them the option of using whatever tool they thought would help them. As a teacher, I was battling students' strong desire to buy both pens and challenging them on their misperception of the answer "buy both." Even with the manipulatives in front of one student showing the correct amounts for both pens, when I asked her how much more, she combined them all together.
