# Multi-age 3–6, mathematics, Year A – Unit 13

This multi-age unit develops the big idea that multiplicative thinking involves flexible use of multiplication and division concepts, strategies and representations.

In this 2-week unit, students are provided opportunities to:

• generate and describe multiplicative patterns and structures (Stage 2)
• use arrays to establish and extend multiplication facts from multiples of 2 and 4, 5 and 10 (Stage 2)
• represent and solve problems using multiplication fact families, arrays and number sentences (Stage 2)
• determine products and factors (Stage 3)
• use partitioning and place value to multiply 2-, 3- and 4-digit numbers by one-digit numbers (Stage 3)
• represent and solve division problems with whole number remainders (Stage 3).

### Stage 2

#### Multiplicative relations A – MAO-WM-01, MA2-MR-01, MA2-MR-02

• Generate and describe patterns
• Use arrays to establish multiplication facts from multiples of 2 and 4, 5 and 10
• Recall multiplication facts of 2 and 4, 5 and 10 and related division facts
• Represent and solve problems involving multiplication fact families

#### Multiplicative relations B – MAO-WM-01, MA2-MR-01, MA2-MR-02

• Use known number facts and strategies
• Use number properties to find related multiplication facts
• Represent and solve word problems with number sentences involving multiplication or division

### Stage 3

#### Multiplicative relations A – MAO-WM-01, MA3-MR-01

• Determine products and factors
• Use partitioning and place value to multiply 2-, 3- and 4-digit numbers by one-digit numbers
• Select and apply mental and written strategies to multiply 2- and 3-digit numbers by 2-digit numbers
• Represent and solve division problems with whole number remainders
• Select and apply strategies to divide a number with 3 or more digits by a one-digit divisor
• Use estimation and rounding to check the reasonableness of answers to calculations
