Maths Strategie's. Week 6 Term 4

1. Sammie measure the distance from his bedroom door to the lounge and it was 5.2m.  It was an extra 2.9 to the couch. What was the total distance from his bedroom to the couch?

5.2 + 2.9 = 8.1

5.0 + 2.0 = 7.0

.2 + .9 = .1.1

7.0 + 1.1 = 8.1

2. The wooden steps at the back door have fallen apart. The drop from the doorstep to the ground is 1.28m. Tiaki puts a couple of layers of concrete blocks down temporarily to reduce the distance. These layers measure .650m.  What is the drop now?

1.28 + .650 = 1.93

0.28 + 0.65 = 0.93

1.0 + 0.93 = 1.93

3. Teams are allowed up to 14 players in the touch competition. If there are 168 players altogether how many teams are there?

14 x 12 = 168

14 x 10 = 140

14 x 2 = 28

10 + 2 = 12

4. There are 9 students from our school who made it to the Auckland Champs for athletics. This was ¼ of the number of students who competed at the Eastern Zones. How many people went to the Eastern Zones?

¼ of 9 = 2.25

9 x 4 = 36

9 x 2 = 18

18 x 2 = 36

5. There are 21 girls to every 12 boys in the class.  The same mix or ratio of girls to boys are picked to go to a special concert If 11 went how many boys and how many girls was this?

21/33         12/33

33 divided by 3 = 11

21 divided by 3 = 7

12 divided by 3 = 4
