## Objective

SWBAT define and explain what it means to divide.

#### Big Idea

When we teach others we build a deeper understanding.

## Intro

5 minutes

We have done a lot of work on understanding division and what it means to diving things up into equal groups (MP2). Turn and talk to your partner about what it means to divide.

Today we are going to create presentation posters explaining what we know about division and showing all of the ways that we can represent division (MP4). I always learn more and understand better when I teach it to all of you, so today you are going to become the teachers and you are going to show all of us what you know!

I think a critical piece of math is explaining our thinking and reasoning. No two people learn in exactly the same way. When students have the ability to articulate what they know and show it through models and examples, it gives me great insight into how they're processing information and it gives other students ideas about how to solve problems or how they can also think about the concept.

## Activity

30 minutes

As a group you will need to discuss and plan how you want to create your presentation. We are all going to have different ideas, so we need to be respectful team mates when we discuss. The only things I will require is that you have a definition and example somewhere on your poster. The rest is up to you! I'm hoping to see all of the unique and creative ways you solve division problems shown on your posters so that I can learn from all of your smart thinking.

I really want to encourage students here to be confident in the ways that they problem solve and reinforce that there is never just one way to do things. The more ways that are shared and celebrated, the more access students have to the information. Students can help teach one another in ways that the teacher can't always do, so I want students to feel empowered to teach us the ways they think about their math.

## Presentation

15 minutes

In my classroom, when students create presentations we have expectations for participation as a good audience member. Students must sit and quietly listen to their team mates and then we share feedback and questions at the end.

Each group chooses a "celebration" at the end of their presentation so that we can celebrate their hard work. These expectations and procedures have been in place since the beginning of the year, so students are very familiar with them. They love celebrating each other's work and having a voice in giving feedback, instead of all of the feedback coming from me.
