### Learning Objectives

- Understanding the importance of ratio as it applies to gameplay within Minecraft, and understanding how to refine ratio within a function.

### Guiding Ideas

Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. Specifically looking at the Common Core Math Standard:

CCSS.MATH.CONTENT.6.RP.A.1

### Student Activities

This activity requires students to have Code Connection open and running with their Minecraft Education Edition.

This activity consists of 2 parts:

Understanding Existing Ratios in Minecraft

Defining Your Own Ratios in Minecraft

## Existing Ratios in Minecraft

Lead a class discussion about ratios, focus on real-world examples such as 1 car has 4 wheels. Come up with a list of real-world examples on the board.

Have students explore their Minecraft world to discover ratios within Minecraft. For example:

1 fishing rod is made from 3 sticks and 2 strings.

Come up with a list of Minecraft ratio examples on the board.

## Defining Your Own Ratios

Have students get into groups of 2-3 and create their own new ratios for Minecraft. Lead them through the following example first. Italicized text is what can be said to students.

*To make jumping more interesting, we’ve defined a new jump mod that has a ratio of 1:5. For every 1 time jump is called, the player moves up 5 blocks:*

Walk students through changing the 5 to other numbers and predicting what the ratio would be. Compare this jump mod to the was the player jumps in Minecraft naturally (for each space bar press, there is a 1:1 ratio of number of blocks the player jumps).

*You can even make a variable ratio, meaning whatever parameter number you put in, the player will jump that many blocks high:*

Walk students through the concept that there are two ratios here:

1:**number** for each time jump is called, the player will go up **number** of blocks.

1:1 the **number** that is passed in is exactly how many blocks the player will move up.

Ask students to define their own ratios using parameters and loops.

### Performance Expectations

Expected outcomes include:

- This exercise can be completed in one class session depending on the experience within Minecraft of your students and the amount of exploratory time given.
- Students should be able to recognize ratios in the real-world and game-worlds.
- Students should be able to decide on creating new ratio rules for real-world inventions or game-world gameplay.
