Starter: Odd and even numbers
Play this game to practise your odd and even numbers
LO: Make equal groups
Pencils come in packs of 20. We need to put 5 in each pot. How many pots do we need?
We could solve this by putting our 20 pencils into groups of 5. We then count how many groups we made:
There are 20 pencils.
There are 5 in each pot.
There are 4 pots altogether.
We could also count in 5s to see how many 5s in 20:
5 10 15 20 – there are four 5s in 20
Task: Work out how many pots you would need if you had:
- 30 pencils with 5 in each pot
- 15 pencils with 5 in each pot.
- 25 pencils with 5 in each pot.
- 12 pencils with 2 in each pot.
- 22 pencils with 2 in each pot.
- 30 pencils with 10 in each pot.
- 40 pencils with 10 in each pot.
- 15 pencils with 3 in each pot.
- 21 pencils with 3 in each pot.
- 24 pencils with 4 in each pot.
