Common mistakes

What learners typically get wrong, and how to fix it.

  • Says the starting number as the first count when counting on.

    Correction: Point to the start number, then say the NEXT number as 'one'.

  • Loses the pattern when crossing a ten (e.g. 28, 29, 20).

    Correction: Use a 100 square so the child sees the row change.

Teacher tips

  • · Use a 100 square and colour each skip-count pattern in a different colour.

Parent tips

  • · Count stairs in 2s or cars in 5s on a walk.

Real-life applications

  • · Counting coins in 5s and 10s, counting pairs of socks in 2s.
