We are learning to use place value to solve multiplication problems using whole numbers.

Times table practice:

5 x 5 = 25                                   7x7= 49

4 x 4= 16                                    8 x 8= 64

3 x 3 = 9                                     11x 11= 121

6 x 6= 36                                    5 x 4= 20

9 x 9 = 81                                   10 x 10= 100

Factors of 16 = 1, 2, 4, 8, 16

Multiples of 8 = 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96.

A prime number is a number that can only be times by 1 and itself to equal itself, for example, 11 x 1 = 11 no other times table can equal to 11 which makes 11 a prime number.

25 x 25 = 625

20 x 25 = 500

5 x 25 = 125

500+125= 625

25 x 245 = 6125

200 x 25 = 5000

40 x 25 = 1000

5 x 25 = 125

5000+1000= 6000+125= 6125

267 x 250 = 66750

200 x 267 = 53400

50 x 267 = 13350

54000+13350= 66750

160x135= 21600

160x100= 16000

AJ’s family are planning to build a treehouse in their garden. Some of Aj’s friends offer to help him to build it.

1. In order to start constructing the house,  AJ needs to get some wood from bunnings. His mum buys 45 planks of wood and his dad buys 132 planks of wood. How many do they have together?

45+132=177

45+32=77+100=177

 2. While building the house, AJ noticed that they were running out of nails so he went to buy some. They have 9 nails left at home. AJ  buys a pack of 145 nails and a pack of 50 nails. How many nails do they have now?

50+9=59+105=164+40=204

3. To have a more stable treehouse, Jacob decided to tie the corner posts of the house to the tree itself. He used 24 cm of rope for the first post, 20cm on the second, 14cm on the third and 12cm on the fourth. How much rope was used? 

24+20=44 14+12=26+44=70cm of rope used altogether

4. The treehouse is almost done; all they need is to paint it. Paschal estimated that they will use 37L of white paint, 15L of green paint and 34L  of brown paint. How many litres of paint would they buy in total? 

15+34=49+30=79+7=86L

5. After finishing the treehouse, AJs’ family made cookies for his friends to thank them for helping. If AJ ate 15 cookies, Jacob ate 10, Paschal ate 6  and Tisa only ate 5, how many cookies were eaten in total?
