Maths today, they didn’t get fractions yesterday
You wrapped yesterday up as “needs another go”, so I’d go back a step before pushing on. Halves and quarters with paper strips first, then the number line.
Warm up. Fold paper strips into halves, then quarters. Ask what stays the same.
Main. Place those fractions on a number line in pairs.
Watch. The four who struggled yesterday. Sit them together and start with halves.
