Chapter 13: Animal Jumps

A frog jumps 2 steps at a time. A rabbit jumps 3 steps. A kangaroo jumps 5 steps. Where do they land after a few jumps? If we mark their landing spots on a number line, we discover number patterns , the times tables come alive!

In this chapter we use animal jumps to play with multiplication, skip counting, and number patterns. By the end you will spot patterns in the numbers around you with the eye of a detective.

What's inside

  • The number line and how to hop on it.
  • Skip counting in 2s, 3s, 4s and 5s.
  • Multiplication as repeated jumping.
  • Number patterns hiding in the times tables.
