1 Multiplying by 10 When we multiply by 10 we are making the number ten times bigger. L.O. - Multiply an integer up to 1000 by 10; understand the effect.

2 Thhtu 1111 x10 In the decimal system, each column has numbers 10 x bigger than the next one

3 Thhtu x10 Lets try it with another number! x x

4 Thhtu 6 60 x10 If we multiply 6 by ten it will move into the next column We must put a 0 in the empty units column to hold the place – 6 x 10 = 60

5 Lets try with some other numbers x 10 = 230 Thhtu 23 Dont forget to add the zero in the empty column!

6 Lets try these together! 48 x 10 = 93 x 10 = 134 x 10 = 256 x 10 = 889 x 10 = Were you right?

7 Thhtu If we multiply 6 by a hundred it will move up two columns We must put a 0 in the empty columns to hold the place – 6 x 100 = 600

8 Lets try these together! 8 x 100 = 15 x 100 = 28 x 100= 134 x 100 = 267 x 100 = Were you right?

9 Now you are going to try some yourselves!
