Skip counting by tens

Skip count by tens (10, 20, 30, 40, 50) and connect each number to that many groups of ten objects.

Skip counting by tens is a fast new trick: 10, 20, 30, 40, 50. Each jump is one whole new group of ten, not just one more.

Ten fingers on you, ten more fingers on a family member, that is 20 fingers in just two jumps. Counting by tens is much faster than counting by ones.

📋 For the teacher
Teach it (10–15 min):
  • Use real groups of ten, such as ten blocks bundled or ten beans in a cup, to make each jump concrete.
  • Count by tens using people: your ten fingers, then a family member adds ten more.
  • Practice the short pattern (10,20,30,40,50) until it feels smooth and automatic.
  • Point out that counting by tens is much faster than counting the same amount by ones.
Talk about it:
  • How is counting by tens faster than counting by ones?
  • How many groups of ten make 30?
  • Can you find 2 groups of about ten objects around the house?

Mastery looks like: They skip count by tens to 50 and connect each number to that many groups of ten.

Common stumbles: Reverting to counting by ones partway through; forgetting a jump and landing on the wrong decade.
