Socks Two by Two

Age 7 Maths

Socks Two by Two

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.
