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.
