Mini Challenge

Creating a Table of Multiples and Divisors

In this activity, learners will team up to build a table listing multiples and divisors for various numbers. They will utilise materials such as poster boards, markers, and stickers to craft a visual display that enhances comprehension of these concepts.

1. Divide learners into groups of 4 to 5.

2. Provide each group with a poster board, markers, and stickers.

3. Each group should select three distinct numbers ranging from 1 to 50.

4. For each selected number, the group must list the first 10 multiples and the divisors.

5. Multiples should be recorded in one column and divisors in another column.

6. Encourage learners to embellish their tables with drawings and stickers for a more vibrant presentation.

7. After constructing the tables, each group should present to the class, explaining how they identified the multiples and divisors.

This activity aims to enable learners to collaboratively and visually practise identifying multiples and divisors, reinforcing their understanding.

**Duration: (25 - 30 minutes)
