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 

145 + 32 =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?

145 + 9

154 + 50 = 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 + 14 + 12

44 + 14 = 58 + 12 = 60

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? 

37 + 15 + 34 =81

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?

15 +  10 + 6 + 5

Show your working as you solve these problems:

145 + 235 = 380 i did 100 + 200 =300 then i add 45+35=80

134 + 127 =262 i added 100 to 127 = 227 then i added 34 then that made 262

1445 + 1564 = 3009 i add 1000 to 1564= 2564 then i added 1445 then that made 3009

1235 + 5643 =6878 i add 1000 5643= 6643 then i add 1235 THAT MADE 5643
