IALT: Talk about what I learnt and did for Maths this week.

1. It costs of $327.55 for Tom’s ski team to take part in a competition.To find out how much it costs for each of the four team members to compete Tom writes 4 x ? = 327.55

How could Tom write this as a division problem?

Tom uses his calculator and get’s the answer 81.8875

What would be a sensible answer for him to write down?

Discuss this with a classmate.

Answer: 327.55 / 4 = 81.8875

B. Rewrite each equation given in red as ? =

Work out the answer. Only use a calculator if you need to. Round your answers sensibly. The first one has been answered for you.

2. During the cricket season Jeetan scored 936 runs in 17 innings. What was his batting average? 936 / 17 = 55

3. Janus had 4.56 kg of jam. He put equal amounts into 11 jars. How much jam was in each jar? 50.16 / 4.56 = 11

4. Rangi paid $26.6 for some beef fillet, which cost $18.79 per kg. How many kilograms did he buy? 26.6 / 18.79 = 1.41

5. Todd paid $19.33 for 4.85 kg of semi-dried tomatoes for a party. How much were they per kilogram? 4.845 hub / 19.33 = 3.98

6. Malaki cut 134.89 m of fishing line into pieces 22.5 metres long. How many pieces did he get?   134.89 / 22.5 = 5.99

7. Sunee is going to Thailand for a holiday. She changes NZ$ into Thai Bhat and gets 18 Baht for every NZ$1. She buys these gifts. How much would they cost in NZ$?

600 / 18 = 33.3 , 1250 / 18 =  69.4 , 1780 / 18 = 98.8

8. Neptune orbits the sun about 6.07 times during a millennium. About how long in Earth years does it take Neptune to orbit the sun once?

1000 / 6.07 = 164.74

9. The circumference of the outer rim of the London Eye is 472.8 metres. The wheel travels at 0.26 m per second. How long does it take to make one complete revolution?  1818.46 x 0.26 = 472.8

10.  Sandi and her family used 126.57 U.S. gallons of petrol on a touring holiday in America. Sandi found out that there are 3.785 litres in one U.S. gallon. How many litres of petrol did the family use for their holiday?

This week for maths I was working with my classmate Gary,Metui and Sifa on this task.To me it was a little bit hard so we went to Ms Komor and asked if she could take us through the problems 1 at a time,and After that we all knew what to do.So we all had to solve one problem each and if we were fast finisher we can solve 2 problems.After all of this maths I think were gone better at maths as a class.I hope you challenge yourself with some hard maths problems.
