Ordering Simple Fractions

Order three or more fractions with the same denominator by placing them on a 0-to-1 number line and reading left to right. Compare top numbers when bottom numbers match.

1 - Getting Started ~4 mins

Illustration for Getting Started Here is a line from 0 to 1, split into eighths. Three fractions are marked on it in a jumbled order: one eighth, four eighths and seven eighths. Which one sits nearest to 0? Which one sits nearest to 1?

👇 Mark your steps as done as you complete them.

2 - Watch and Notice ~9 mins

Four number lines, each running from 0 to 1 and split into equal steps. On each one, three fractions with the same bottom number are already marked. Look at where each fraction lands, and get ready to say which is smallest and which is biggest before we read them off left to right.

👇 Mark your steps as done as you complete them.

3 - Try It Together ~11 mins

Key point

Today we work this one through together on the board. The line is marked in fifths and it carries three markers, one for each fraction. Three pupils come up in turn, and each drags one marker onto its own fraction:

1/5 — the first marker
4/5 — the second marker
2/5 — the third marker

When all three markers are down, we read the finished line from left to right and say the three fractions in order, smallest first.

Place the three fractions, then read the order

4 - Order the Fifths in Your Copy ~3 mins

COPYBOOK MOMENT

In your maths copy, draw a line from 0 to 1 and split it into fifths. Mark one fifth, four fifths and two fifths on the line. Then write the three fractions in order from smallest to biggest.

+10 XP

5 - Class Challenge ~8 mins

Key point

Today we place one fraction at a time and check it. The line changes to match each fraction. We place three quarters, then one fifth, then five eighths, then seven tenths. Before each one, predict where it will land — nearer 0, nearer 1, or right in the middle.

Place each fraction and check
