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).
