What happens when you split one whole into 100 equal parts?

Each equal part is a fraction called a hundredth, you can also write this as a decimal: 0.01.

Today's lesson will look at counting in hundredths, what happens when you have 10 or more hundredths and using place value grids, number lines and hundredths squares.

The hundredths square

The video below begins with a picture you’ve probably used before. It’s a hundred square. But today, think of this picture as a hundredths square. The whole square represents 1, and each part represents a fraction or a decimal.

The picture will help us count in decimal steps.

Next watch the video below to find out how decimal counting continues past 0.09.

See how you can exchange 10 hundredths for 1 tenth and some different methods to do this.
