maths mate sheet 5 term 3 question 22

Predict: I predict that i will have to use  “working backwards.”

Read: I think of a number, divide it by 2 and then add 12. If the result is 20, what was the original number?

Clarify:  nothing to clarify.

Big Question: What was the original number?

Mathematicians toolbox: I used  working backwards.

Solve : first i worked backwards so i got 20 and added 12 this becomes 32 then divided that by 2 which equalled to 16 and the answer was 16,

Conclusion : i learnt that working backwards was going to help me get the answer to questions like this were i don’t have the original number.

maths mate sheet 6 term 3 question 22

Prediction: I predict that I will have to use the 4 operations.

Read: I think of a number, add 15 and then divide by 4. If the result is 5, what was the original number?

Clarify: nothing to clarify.

The Big Question: What was the original number?

Mathematicians Toolbox: From the Mathematicians Toolbox I will be using “Work backwards”.

Solving: First i look at the problem and worked backwards, so we start at 5 and work backwards. What can be divided by 4 to get 5 so I times those to numbers together to get 20 and then take away 15 to get 5 so the original number is 5. (inverse operations).

Conclusion: I feel that I worked well and did the problem easily after I looked over what to do.

100 word challenge week 1 term 3 “finally we could make a start”

The bush fire season just finished and our house burned up because  we left to go to a safer place all our furniture was burned but luckily our memory’s were not  so now that we have nothing to worry about, finally we can make a start to our new lives and start a better future and also build a house that is more bush fire ready, finally we can start a new everything and become the best we possibly can but that of course is until nest fire season then the same thing will happen and we will build again!

BTN week 5

 

Stray dog in the Himalayas can be aggressive and can also carry diseases. They go hunting and attack people and other dogs. 15 people come into the docters every day from dog bites, from that they can also pass on a disease called rabies they have an antibiotics to make the desease go away but they go out of stock.

Two people have come and now are preforming a huge numbers of de-sexing  700 in total. But they wont to reach 1000 before the season ends. After the dogs come they leave after 5-6 days of having the operation. Unfortunately there aren’t enough vets there to finish of the program and now they are un sure of what

BTN week 6

A long time ago, kids around the world suffered from a disease called polio. It was really contagious and the symptoms could be really serious. In the worst cases kids suffered a lot of pain, many lost the use of their legs, and ended up with lifelong deformities.

In Australia, 40 thousand people were diagnosed with polio between the 1930’s and 1980’s, but for us, a vaccine was developed in the 1950s and polio was wiped out in Australia.

But overseas many children don’t have this vaccine, so a team of doctors go out to peoples home to vaccinate their children. Although they have found a cure some people don’t want to have their children take the drops because some think that America is trying to hurt their children, but that  is not true, after all this they are still trying to get rid of polio.

maths mate term 3 sheet 4 question 24

Predict: I predict I will have to use guess check and improve, problem solving and addition.

Read: each bead has a value according to its colour. The value of the first 3 are given. What is the value of the last string?

Clarify: nothing to clarify.

Big question: how much is the last string of beads cost?

Mathematical toolbox: I used “guess check and improve”.

Solve: first I worked out that because the first answer was 16 I worked out that white beads were 7, dark beads were 2 and light beads were  5 my answers were right for them so I went to the answer and got 22.

Conclusion: the answer 22 turned out to be correct so my working out was correct.

 

maths mate sheet 2 term 3 question 22.

Predict: I predict that I will have to use addition in this problem.

Read: Carl looked at the page numbers on the open book in front of him. The left and right page numbers added to 333. What were the page numbers?

Clarify: nothing to clarify.

Big question: what are the two page numbers?

Mathematical toolbox: I used guess check and improve.

Solve: to solve this answer I divide 333 by 2 and got the answer 166 r1 so I just said to myself they were 166 and 177.

Summary:  in conclusion the answer I got was correct, 166 and 177.

 

maths mate sheet 3 term 3 Q24

Predict: i predict that i will have to problem solve and use addition.

Read: each bead has a value according to its colour. The values of the first three strings are given. What is the value of the last string?

Clarify: nothing to clarify.

Big question: What is the value of the last string?

mathematical toolbox: i used guess check and improve.

Solve: to solve this question I first looked at the first string and saw 4 gray beads and 1 dark bead the answer was 22 but to first get 22 I had to work out what the beads are worth so I first the gray beads I found worth 5 and so the dark one had to be worth 2. Next it came to 21, there was 2 white beads, 1 gray bead and 2 dark beads. I added the 2 beads I know and it came to 9 the left over was 12 so because there was 2 of the white beads the answer  was 6. I already knew the next one so i went onto the last one, there was 1 white bead, 3 gray beads and 1 dark bead, I worked out the answer was 23.

Summery: when I first saw the question i couldn’t work it out but now i know how to do it and the answer  23 turned out to be correct.
