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:

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

**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.
