Maths KS1: subtracting 1 from 5

Rodd is trying to squeeze 5 jumpers into his camping rucksack.

He has to take 1 out, and shows us that we can use subtraction to work out how many jumpers are left inside, without having to take them out and count them again.

We join in with Rodd and learn that ‘5 take away 1 leaves 4’, through counting with his special abacus, finger counting, sleeping bag ‘moves’, counting back on the number track, and singing a number rap.

Teacher Notes

In a circle, students could make up variations of ‘When I went camping, five squirrels I saw, but one ran away, so that left four!’.

Students could lay out paper plates for a camping picnic, with five pretend food items on each.

They could turn their backs while another student takes away one item from one plate.

The others would then need to spot what has been taken and talk about how ‘five take away one leaves four’.

Students could pretend to pack to go on a very cold camping trip.

Using a pile of jumpers, hats and scarves, students could count how many they start with, squeeze as many as they can into a bag and then count how many are left.
