Socks Two by Two
Age 7 Maths
Socks like to go two by two. Here two pairs match up, and one red sock is left with no partner.
Examples
- On washing day you match socks two by two and see if one is left over.
- Sharing 8 grapes with a friend gives 4 each, with none left over.
Key takeaways
- A number is even when everything has a partner.
- A number is odd when one is left over alone.
