Here is a line that starts at 0 and ends at 1. Where would one half live on this line? Closer to 0, closer to 1, or right in the middle? Show me with your hand where you think it should go.
Take three hands-up answers, not open call-outs. Give five seconds of quiet think-time before any hands go up. Do not confirm the answer yet, the middle idea is what Watch and Notice will prove.
The interactive shows lines from 0 to 1, split into equal steps. Watch where each fraction lands, and keep an eye out for two fractions that end up in the same place.
Two-step line: one mark between 0 and 1, one half sits on it, one jump from 0, halfway along. Ask the class to agree it's one jump from 0.
Four-step line: three marks. Have them predict all three before revealing. One quarter one jump, two quarters two jumps, three quarters three jumps. Reveal together, count the jumps across so each is confirmed. Stress every jump the same size, evenly spaced.
Two quarters lands on one half: same point, two names. This is the key moment. Don't move on until they can repeat it back.
Now we place three fractions together on the same four-step line, in this order: one half, then one quarter, then three quarters. The line stays split into four equal steps the whole time. Each time we count the equal jumps from 0 before we check. We will save one third for the Class Challenge, because that fraction needs a different line.
This round is for talking it through together. Pupils take turns at the board and the class agrees or corrects out loud.
Keep the line in quarters throughout — all three fractions here sit on the four-step line. For each placement, ask 'how many jumps from 0?' and revoice a strong answer: so three quarters is three jumps when the line is cut into four. One third is deliberately held back to the Class Challenge, where the line switches to three equal steps.
In your maths copy, draw a 0-to-1 number line and mark it into four equal steps. Then label one half and three quarters in their correct places. Count the equal jumps from 0 to be sure each one lands right.
Walk the room glancing at whether the four steps are roughly equal and whether one half lands on the second mark — this is whole-class copybook practice, not marking. No individual grading.
Now we work through these placements together, one at a time: place one half, then one quarter, then three quarters. Count the equal jumps from 0 each time, then press Check to confirm before moving on. For the last one, one third, the line changes to three equal steps instead of four, so the marks sit in new places. Predict where one third will land before you drag.
These are the practice questions — pupils take turns at the board, check each answer, and the class confirms before moving on. Keep the board work brisk rather than over-explaining.
Add a how many jumps from 0? callout on each placement. The one third placement is the stretch — the line now shows three equal steps, so its mark sits after the quarter mark pupils are used to. Let the class predict where it will land before the reveal.
