Multiplication: reSolve Market
View Sequence overviewRelated multiplication and division facts can be found in the array. These related facts are known as a fact family.

This activity is a variation of the earlier activity, Making arrays.
Use slide 34 of the reSolve Market PowerPoint to explain to students the Making fact families activity.
Students work in pairs. Each pair needs a set of cards and a collection of counters. Each student needs their own copy of Making fact families Student sheet.
Completing the activity
- The first student selects a number card. Both students collect that number of counters.
- Each student works on their own to arrange their full collection of counters into an array. They record a picture of their array and the corresponding fact family on their student sheet.
- The students compare their arrays and facts and discuss the similarities and differences that they notice.
- The second student selects a card and the pair repeat the activity.
Making fact families
Student attention is focused on the structure of their array as they record its details in their student sheet. In this version of the game, students use the rows and columns in the array to determine the fact family for the array, that is, multiplication and division facts for that array.
The numbers selected for this activity each have multiple factors which will increase the likelihood that students will make different arrays to their partners. This allows students to compare arrays and see that some numbers can be represented using different multiplication facts. Building different rectangular arrays for the same number provides students with experiences that enable them to recognise and identify factors.
