Learn to play ** Diffission**, a fraction puzzle game! Play the game's

**Theory**: This lesson introduces your students to fractions and the fraction puzzle game*Diffission*.**Play**: Students play the game at their own pace.**Share & Discuss**: These questions focus on the playing experience and fractions.

- A
**fraction**means**part of a whole**. The whole is defined as**1**. - The fraction
$\frac{1}{3}$ means you have a single third. You need three thirds ($\frac{3}{3}$ ) to have a whole.

It can be a great idea to go over the images: what fraction does each pie diagram represent?

Use your own sources and the ones below to teach students about fractions and related concepts:

**Play Diffission!**

To begin playing, click the screen.

- Slice fractions into smaller pieces until you have the right number of pieces (
**as displayed at the left bottom corner of the screen**). - In every level, you need to make
**equal pieces**of each separate piece. They can have a different shape, but they must have the same number of squares. - You must click on as many pieces as the numerator of the right number of pieces is to solve a level.
- If you have a problem with a level and need to restart, click on the
**reload icon**at the top left corner.

- What did you think of
*Diffission?* - How far along did you get?
- Was there any puzzle that was really difficult for you? Which one?
- Did you have any trouble playing the game?

Which fraction is the image below?

Explain what a **numerator** is.

The **numerator** is the top number of a fraction. It simply means how many units of the fraction you have:

Explain what a **denominator** is.

The **denominator** is the bottom number of a fraction. It means how many units of a fraction are necessary to have a whole:

How would you write these fractions: one third, two quarters, four fifths.

What is the difference between 4/4 and 6/6?

Technically, nothing at all: they are both wholes (a **1**). This is a trick question. If they would not be wholes, they would not be equal: *are* the same amount! More on fraction comparison in the next lesson.
