Investigate number sequences, initially those increasing and decreasing by twos, threes, fives and ten from any starting point, then moving to other sequences. (ACMNA026)

LO: To use number sequences or patterns to count more efficiently.


  • When counting there can be patterns
  • Patterns can increase (get bigger) or decrease (get smaller)


  • that there are more efficient ways to count numbers than one-by-one.


  • I can count using patterns like 2, 3, 5 and 10.
