Multiplying by 10 I have completed the sums to match the bar model. Are they the same as you recorded? 11 X 10= 110 32 X 10= 320

Which of these ways of representing multiplying by 10 is the odd one out? Why? 30 10 30 3 3 3 3 3 10 10

How did you do? Did you come up with a similar answer and explanation? 30 30 3 3 3 3 3 10 The part-whole model is the odd one out because it shows 3 equal groups of 10 whereas the bar model and number shapes both represent 10 groups of 3. 10 10

Your task Add two more rows to the table, showing 52 X 10 and 93 X 10. What else can you use to show multiplying by 10? There is a challenge on the next slide.
