Holiday pay

Name of problem: Holiday pay

Describe the problem: You would get $60 of holiday pocket money and you spent ¾ on toys and ⅓ was left on lollies. Then you bought 2 pies $2 each so altogether $4. How much money is there left to save? What fraction of pocket money is left?

These are the strategies and knowledge I used to solve the problem. (add more bullet points for each step) First I halved the 60 and then I got 30, so I halved that too and then I came to fifteen, but I can’t half the fifteen because it is an odd number. Next I did ¾ -⅓ = ½ (I am not sure if it’s right). Then I did 30-4=26 and half of 26 is 13 and (this is so wrong) I thought half of 13 was 6/7, I thought it was the answer. I showed the teacher and Mr Blakey said it was wrong so Mr Blakey helped us and we used the fake money he told us how to take away fractions. Our answer was 6.

Describe how you used 2 learning muscles:   Imitation I used my imitation muscle when I was doing ¾ -⅓ = ½ because Lauryn thought it was 2/1 but then I told her it was ½ because the biggest number is always at the bottom. Making Links I used the making links muscle with my subtraction for taking away the money.

Maths task

We did some cool math tasks where we had to work out a dimensions for a swimming pool and three more tasks. Here is my work sheet and how I worked it out...first I will be showing you my swimming pool sheet and then I will be showing you my other sheets...enjoy!

                                                                                                                                                             

Parkvale school

The Parkvale pool needs to be drained and refilled because it has become too dirty.

These are the dimensions of the pool:

     12x25=300

                                                               10x25=250

                                                                                                        2x25=50            

                                                                                                       300x2=600

•  How much water in m3 is needed? 12x25x2=600,00
• How many litres of water is needed?

Extra for Experts:

• The tap to fill the pool pumps 50,000 litres per hour. How many hours would it take to fill the pool?
• For each 1000 litres of water, 1 gram of chlorine is needed. How much chlorine needs to go into the pool?
• Design a different pool in 3D (like above) and work out its volume in m3 and litres. Tip: start with a cube or rectangle

Stage 5&6 Volume

Do your working out in your maths book - show all of your working out.

• A container has a volume of 96m3. What are all the possible dimensions of this container?

• A pool has a volume of 180m3. What are all the possible dimensions of this container?

• A lunchbox has the volume of 280cm3 What are all the possible dimensions of the lunch box?

1x28x10=280cm3

28x10x1=280cm3

10x1x28=280cm3

10x28x1=280cm3

1x10x28=280cm3

28x1x10=280cm3

6x2x8=96m3

16x2x3=96m3

2x3x16=96m3

3x2x16=96m3

2x8x6=96m3

8x6x2=96m3

8x2x6=96m3

   









15x12x1=180m3
12x15x2=180m3
1x12x15=180m3
15x1x12=180m3

Maths

Maths Reflection

What I enjoyed… I enjoyed making perimeters and marking out the area.

What I found difficult… The thing I found the most difficult was multiplying fractions because I didn't really get it so I need to practice more.

What I learnt… I learnt that you can make 140 in lots of different ways. (e.g) 70m and 50m

What I still need to learn or practice… Definitely multiplying fractions.  

Maths task time

Time

• I learnt that there are lots of different answers to just one question.
• Something I found challenging was the last question because I didn’t know how to write it down.
• I enjoyed finding out different answers to the problem because it was really fun and challenging.
• I was able to do the task because I got some help from some other people in the hub and when I was sorted so I went into the cave.
