Activity:to perform mental calculations [lo 1.9.2]
1. How well do you know your 12 × table? Count in 12’s and colour each answer in green.
If you do this correctly you will find the answer to the following:
Multiplication is actually repeated _________________________________________

- Can you find any more multiples of 12? Colour them in blue.
What word does your answer spell? _______________________________________
2. LET US REVISE!
Fill in the missing answer:
In 24 x 17 = 408, we call:
17 the________________________________________________________________
408 the_______________________________________________________________
24 the________________________________________________________________
24 and 17 ______________________________________________________ of 408
408 a ___________________________________________________________ of 17
Assessment
Learning Outcome 1: The learner will be able to recognise, describe and represent numbers and their relationships, and to count, estimate, calculate and check with competence and confidence in solving problems.
Assessment Standard 1.9: We know this when the learner performs mental calculations involving:
1.9.2: multiplication of whole numbers to at least 12 x 12.
