=Work these problems out in your mind and discuss your strategies with your group. Show a couple of strategies below, but the rest of the questions can just be answered

29 x 20 = 580 2. 33 x 15 = 495 3. 76 x 24 = 1824 4. 65 x 17 = 1105

5. 72 x 15 = 1080 6. 33 x 16 = 528 7. 34 x 31 = 1054 8. 42 x 26 = 1092





9. 90 ÷ 30 = 3 10. 280 ÷ 40 = 7 11. 300 ÷ 12 = 25 12. 625 ÷ 25 = 25





Word problem of the week:


For every 8 girls in a school, there are 12 boys. If there are 60 students in the school, how many girls and boys are there in the school? 8 x 3 = 24, 12 x 3 = 36, 24 + 36 = 60, 24 girls to 36 boys





Wicked word problems!

Solve these problems. Write down your strategies:

Jermaine has 120 lollies to share between some friends. How many lollies would each friend get if there were 8 altogether? 8 x 10 = 80, 8 x 5 = 40, for each kid there is 40 candies. 1:40

It takes 3 minutes to hang out 12 items of clothing. How long will it take to hang out 36 items? 12 + 24 = 36, 3 + 24 = 27, 27 minutes to hang out 36 items of clothing. 27 : 36

A pancake recipe calls for 3 cups of flour and 2 eggs. Marika is going to make several batches to bring to the garage sale. If she wants to use 9 eggs, how many cups of flour will she use? Half of 2 is 1, half of 3 is 1.5, 2 x 4 = 8, 3 x 4 = 12, + the half = 9 : 13.5.

At the pools, one lifeguard is required for every 25 people.If there are 150 people booked to swim, how many lifeguards need to be working? 25 x 6 = 150, there are 6 lifeguards needed for 150 people to swim

The pools also say that one adult can only look after two children under 5. If Pt England Kids are going swimming and they are taking 30 children, how many adults will they need? 2 x 15 = 30, 15 parents are needed for 30 kids to swim safely.

If the ratio is 2:8 then it is also ?:56, 8 x 5 = 40, + 16 {2x}, 7 : 56
