## Objective

SWBAT review the divisibility rules using a foldable.

#### Big Idea

A hot dog fold serves as a divisibility rules study guide.

## Creating the Foldable

10 minutes

To begin the process of creating our Divisibility Rules Foldable, each student will receive a plain piece of white paper. I will demonstrate the folds and cuts as I explain the steps to students (see Creating a Foldable).

1. Students should fold the paper in half, the long way.  This is called the "hot dog" fold.
2. Students should fold the paper in half 3 times to create 8 tabs.
3. Students should unfold the paper back to the "hot dog" and cut along each of the creases.

Our goal is for it eventually to look like Divisibility Rules Foldable.

## Designing the Foldable

25 minutes

We are creating our Divisibility Rules Foldable to serve as a study guide for students. Tomorrow we will have a quiz on Divisibility. I show students an example to give them an idea of the final product.

The front of each tab should read:

• Divisible by 2
• Divisible by 3
• Divisible by 4
• Divisible by 5
• Divisible by 6
• Divisible by 8
• Divisible by 9
• Divisible by 10

Inside each tab my students will write:

1. Definitions for each Divisibility Rule
2. Hints about each rule
3. Examples that will help them remember the rules

Each student should create their own foldable.  As students work I remind them regularly that the foldable is only as good as they make it.

## Lesson Review

5 minutes

I will handout and read to the class the Divisibility Rules Poem. We've taken several days to learn the rules carefully and along the way I have encouraged students to remember them. We've also practiced articulating them, in class discussions and presentations of student work. As we come to the end of our learning, I give students this poem because I think that it helps some of my students to recall the rules better if they remember it in this form. There are students who remember text in lyrical form better than concepts expressed as a list of rules. And, in the end it is most important that my students can recall the given information when they need it.
