• recognise and use the symbols for multiplied by (×), divided by (÷) and equals (=)
• link multiplication and division facts using groups or arrays,
Eg
-
explain why a rectangular array can be read as a division in two ways by forming vertical or horizontal groups, eg 12 ÷ 3 = 4 or 12 ÷ 4 = 3 (Communicating, Reasoning)

• model and apply the commutative property of multiplication, eg 5 × 8 = 8 × 5

CONTENT
Students:
Recall multiplication facts of two, three, five and ten and related division facts (ACMNA056)
OUTCOMES
A student:
› uses appropriate terminology to describe, and symbols to represent, mathematical ideas MA2-1WM
› selects and uses appropriate mental or written strategies, or technology, to solve problems MA2-2WM
› checks the accuracy of a statement and explains the reasoning used MA2-3WM
› uses mental and informal written strategies for multiplication and division MA2-6NA
Multiplication and Division 1
Represent and solve problems involving multiplication using efficient mental and written strategies and appropriate digital technologies (ACMNA057)
• use mental strategies to multiply a one-digit number by a multiple of 10, including:
- repeated addition, eg 3 × 20: 20 + 20 + 20 = 60
- using place value concepts, eg 3 × 20: 3 × 2 tens = 6 tens = 60
- factorising the multiple of 10, eg 3 × 20: 3 × 2 × 10 = 6 × 10 = 60
* apply the inverse relationship of multiplication and division to justify answers, eg 12 ÷ 3 is 4 because 4 × 3 = 12 (Reasoning)
