Number > Multiplication and Division

Australian Curriculum Version 9 Says:

Multiply and divide by one-digit numbers using repeated addition, equal grouping, arrays, and partitioning to support a variety of calculation strategies.

What this means

Connect concepts of multiplication and division.

  • Repeated addition (skip counting) involves repeatedly adding the same number and can be shown on a number line. For example,
  • An array (rectangle) is another way of developing multiplication. See 3 rows of 5 vs. 5 rows of 3.
  • Connect 3 × 5, 5 × 3, 15 ÷ 5, 15 ÷ 3

Tips

  • Arrays are ideal for developing tables knowledge as 3 × 5 may be linked to 5 × 3 by rotating the array. Likewise, the rows and columns in an array show links to division.
