Understanding Ratios with Minecraft

This video tutorial introduces the concept of ratios using the popular game Minecraft. The teacher explains ratios as a comparison of two quantities and demonstrates this through mining trips in the game. The first example involves finding the ratio of diamonds to coal, the second example uses copper and iron, and the final example involves redstone and netherite. Each example is shown in three different ways: a model, a numerical ratio, and a written statement. The video aims to help students understand and apply the concept of ratios in a fun and engaging way.

What is a ratio?

• A comparison of two quantities showing their sizes in relation to one another.

• A way to multiply two numbers together.

• A mathematical operation to find the sum of two numbers.

• A method to divide a number into equal parts.

In the first mining trip, what is the ratio of diamonds to coal?

• 7 to 4

• 3 to 5

• 4 to 7

• 5 to 3

What is the first step in finding a ratio during a mining trip?

• Identify the quantities to compare.

• Calculate the total number of items.

• Multiply the quantities together.

• Divide the quantities by each other.

Which of the following is NOT a way to write a ratio?

• Using a model

• Using a statement

• Using a graph

• Using digits

What is the purpose of using a model to represent a ratio?

• To visually compare two quantities.

• To calculate the sum of two numbers.

• To find the difference between two numbers.

• To multiply two numbers together.

What is the ratio of copper to iron in the second mining trip?

• 6 to 8

• 8 to 6

• 5 to 7

• 7 to 5

How can the ratio of 8 copper to 6 iron be expressed in a statement?

• For every 8 copper, there are 6 iron.

• For every 6 copper, there are 8 iron.

• For every 7 copper, there are 5 iron.

• For every 5 copper, there are 7 iron.

Why is it important to write ratios in different ways?

• To understand and communicate the comparison more effectively.

• To make the numbers smaller.

• To make the numbers larger.

• To confuse the reader.

In the final example, what is the ratio of Redstone to Netherite?

• 4 to 5

• 5 to 4

• 3 to 2

• 2 to 3

Which statement correctly describes the ratio of 2 Redstone to 3 Netherite?

• For every 5 Redstone, there are 4 Netherite.

• For every 4 Redstone, there are 5 Netherite.

• For every 3 Redstone, there are 2 Netherite.

• For every 2 Redstone, there are 3 Netherite.
