Fascinating Fact:

High five hands. One hand is 5 fingers. Two hands are 10. Count 5, 10, 15 using fingers.

In KS1 Maths, children learn to skip count in fives using fingers, tally marks, and number lines. This builds quick addition, helps read minutes on clocks, and supports early multiplication.

  • Skip counting: Counting by a number that is not 1, such as 5, 10, 15, 20.
  • Tally marks: Quick lines grouped in fives to show a total.
  • Pattern: A repeating rule in numbers, like endings 0 or 5 when counting in fives.
How do I teach counting in fives to Year 1?

Begin with hand prints or gloves, then a number line. Point and say 5, 10, 15, 20, clapping on each jump of five.

Why do numbers end in 0 or 5 when counting in fives?

Each step adds five, so the ones digit alternates 5, 0, 5, 0. Children can spot and rely on this repeating pattern.

How does counting in fives help with time?

The minute marks around a clock are groups of five. Knowing 5, 10, 15 helps read minutes past the hour.
