Talofa lava, during maths today we worked on a challenging maths problem (personal opinion). Below is the problem.
With the brain of my peers I finally understood the problem. Here was their working out:
1/8 + 1/8 = 2/8
2/8 - simplify
2 ÷ 2 = 1
8 ÷ 2 = 4
________
= 1/4
Meaning I could use the 1/8th cup to measure the cocoa powder.
This week for my groups math's we just did problem solving. The writing in the black are the questions and the blue are our answers. These answers were by me and Valerie. (helped by Mrs Pome'e

What is the difference between 150 x 150 and 134 x 166?
The difference is 256 because
150x150 = 22500
134x166 = 22244
22500 - 22244 = 256.

Joe made a trip from Bluetown to Redtown. On the first day he travelled half the distance between the two towns. On the second day he travelled half of the remaining distance. He then had 100km left to travel. How far is it from Bluetown to Redtown?
Its 400km all together because
A quarter of the distance is 100km and the other three quarters is
300km and all together it's 400km..?

A cake weighs 1.5kg. If the cake were cut into 5 equal pieces, how many grams would each piece weigh?
1500/5 = 300g
So convert 1.5kg into grams gives us 1500g then we divided by 5
= 300

Sue is allowed to watch 40 hours of television each week. If she watches 20 hours during the weekend, how many hours on average does she watch each weekday?
So every day she watches tv for 4 hours
40h - 20h = 20h left
20 / 5 days = 4 hours a day.

What is the difference between the sum of the odd counting numbers between 20 and 30 and the sum of the even counting numbers between 20 and 30?
21, 23, 25, 27, 29 odd numbers
22, 24, 26, 28, 30 even numbers
So we added the odd numbers = 125 and the even numbers to 150
150 - 125 = 25.

In parking meters downtown you can get 15 minutes parking for 10c. Dad put a 50c and a 20c piece into the parking meter at 3:15pm. At what time did the parking meter expire?
It expires at 5:00pm because every 10c will give you 15min
70c will give you 1.45min.
So your 70c will take you up to 5:00pm

Freda and Fred ladybird were playing a jumping game on the number line. Fred can jump three numbers at a time; Freda can only jump two numbers. Fred started at 1 and Freda started at 30. If they both jumped together, how many jumps did the ladybird with the least number of jumps make to get to 100?
Fred at 33 jumps
Freda at 35 jumps
100/3 = 33 r 1
100 - 30 =70
70/2 = 35 jumps
Capacity: I understand that capacity Is how much space inside of a 3 dimensional object. It’s how much space that
Volume: I understand that volume is how much space the 3 dimensional object occupies.
4 kilograms - 40 minutes in one kilogram each
40 + 80 + 120 + 160 =160
