Learning Objectives
Indicator: B6.1.2.3.1 - Determine basic division fact up to 81
By the end of the lesson, learners can:
- Recall division facts for quotients up to 81 when dividing by numbers from 1 to 9.
- Identify numbers divisible by 6, 8, 9 and 11 using simple divisibility tests.
- Apply known multiplication facts to find related division facts (the inverse relationship).
- Use a multiplication chart to find quotients and play games that require rapid recall of division facts.
- Justify whether a given number is divisible by 6, 8, 9 or 11 with clear reasoning.

Exemplars (from the NaCCA curriculum)
E.g. 1. Investigate numbers that are multiples of 6, 8, 9 and 11. How do you know a number is divisible by 6, 8, 9 and 11? (This is also known as the divisibility test). E.g. 2. Draw a 6 by 6 multiplication chart and use it as a game board to play the 3-in-a-line game with a pair of dice or playing cards. Players take turns in throwing a one dice and mark (or cover) a number that can be divided by the results (i.e. a quotient). The winner is the one who obtains three numbers in a line.
