Multiplication: Making Robots

Australian curriculum number (ACMNA031)

Who is this sequence for?

This task has been designed for students in Year 2. Students will need to have some familiarity with multiplication concepts and early strategies for solving multiplication problems. The task draws on students’ knowledge that multiplication can be represented as equal groups, repeated addition and also in an array formation. Students will apply and build on this knowledge and create connections to multiplication as a Cartesian product.

Summary of learning goals

The resource introduces the key idea of multiplication as a Cartesian product, using the language of “for each”. Students explore the total number of different robots that can be made using three heads, three bodies and three feet. The students represent the different combinations for the robots as array.
