maths mate sheet 5 term 4

Predict: I predict that i will have ti use addition

Question: which deal costs less per gram?

clarify: I have nothing to clarify.

Big question: which deal costs less per gram?

Mathematicians toolbox: i used have i seen a similar problem.

Solve: Firstly, i had to double $3 and 250 so double $3 and u get $6, and if we double 250 it is 500. So because it has $5 for 500g and $6 for 500g it means that A was cheaper by $100.

summary: my answer was a because 3+3=6 and 250+250=500 and A was cheaper.

maths mate sheet 7 term 3 question 22

Predict: I predict this will be about working backwards.

Read: I think of a number,multiply it by 3 and the  divide by 2. If the result is 18, what was the original number?

Clarify: I had nothing to clarify.

Big Question: What was the original number?

Mathematicians toolbox: I used working backwards.

Solving: First i new that i needed to work backwards so i needed to use inverse operation so it became 18 times 2 divided by 3 and the answer is 12. i was working backwards and using inverse operations.

Conclusion: I learnt that you need to work backwards in these questions, like theses and use inverse operations. my answer in the end turned out to be right.

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.

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.

maths mate sheet 1 term 3 question 24

Predict: i think that i will have to use addition.

Read: each bead has a value according to 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:i looked at the numbers with the answer given and worked out that the white  beads = to the value if 5 then the light beads = to the value  of 4. the = to 22. in the next sum the dark beads were worth 6 points.  in the last sum there was 1 white bead, 2 light beads and 2 dark beads that added to 25.

Conclusion: the answer was 25.

maths mate term 2 sheet 8, 2014

Predict: I predict that I will have to use subtraction.

 

Read: A single digit number belongs in each circle, and it must equal the difference between the two numbers it sits on. What number belongs in the shaded circle?

Clarify: nothing to clarify:

 

The big question: what number belongs in the shaded circle?

 

Mathematical toolbox: guess check and improve and have I seen a similar problem.

 

Solve: around the shaded circle there is a 2 and I worked out that above that is a 5, nest I needed to find out was 2 – x = and I figured out that x (algebra) = 7.

 

Summery: you have to read the question carefully to find out what this question means.

Maths mate sheet 7 question 23 2014

Predict: I predict that I will have to use addition.

Read: Jack’s car can travel 15 kilolitres per litre of petrol. He leaves Dubbo with 30 litres of petrol in his car and drives toward Maitland, which town will he be closest to when he runs out of petriol?

Clarify: nothing to clarify.

The big question: which town will he be closest to when he runs out of petrol?

Mathematical toolbox: have I seen a similar problem.

Solve: first I thought to myself that I had to multiply 15 and 30 so I did that and my answer was 450. After I had to add 200, 150 and 100 because those were kilometres between each town, and the answer for that was 450 as well and then 450 – 450 = 0 and he lands at Singleton.

Answer: he arrives at Singleton when he runs out of petrol.
