Number Sequences by 2s,3s,5s,and 10s (2)

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.
