Fractions and Decimals Review

Review the key ideas from fractions: naming, comparing, finding fractions of amounts, and matching decimals. Use pizzas and grids of tenths to show what you have learned across the module.

Warning: Your screen size is quite small for viewing this. Rotate your device into landscape mode if you can.

1 - Getting Started ~4 mins

Look at these two maths tools on the board: a pizza cut into slices and a grid of tenths.

If I asked you to show me one half, how would you show it on the pizza? And could you show the same one half on the grid too?

👇 Mark your steps as done as you complete them.

2 - Watch and Notice ~9 mins

Each pizza on the interactive shows a fraction shaded, and some carry a decimal name in the label underneath. Look at how the piece size depends on the number of slices on each pizza, and read each fraction and decimal together.

👇 Mark your steps as done as you complete them.

3 - Try It Together ~8 mins

Now we build and name fractions together on the pizza. First one third, then three quarters, then seven tenths, and finally one half again so we can say its decimal.

Note

Some of these have a decimal twin and some are name-only:

One half is also 0.5.
Seven tenths is also 0.7.
Three quarters is also 0.75.
One third is name-only, no tidy decimal today.

Predict what each one will look like before we cut it.

Build and name the fraction

4 - Work It in Your Copy ~3 mins

COPYBOOK MOMENT

Before you open your copy, we work one example together on the board.

Find one third of 6 by sharing into equal groups.

Draw 6 dots.
Share them into 3 equal groups (the bottom number tells how many groups).
Count how many land in one group. That amount is one third of 6.

Each group has 2, so one third of 6 is 2.

Now order fractions that share the same bottom number. Look at one fourth, three fourths and two fourths. Bottoms match, so compare only the tops: smallest top is the smallest fraction. Order: one fourth, two fourths, three fourths. A quick shaded bar beside the line proves it climbs.

In your maths copy, show me three things you learned this module:

Find one quarter of 8
Write one half as a decimal
Order one fifth, three fifths and two fifths from smallest to biggest

Draw a quick shaded bar beside the ordering to prove your line climbs.

5 - Class Challenge ~8 mins

Key point

Now we work through these together on the pizza, and each one is a step harder: shade 0.1, then 0.5, then 0.3, and finally 0.25. Predict where each shading will land before we check it.

The last one, 0.25, links back to a fraction you have already met, so predict the slices and the shading before you check.

Shade the decimal
