Maths Mate Sheet 8 Term 4 Question 22

Predict: I predict that it will be about money.

Read: Which deal costs less?

A] 75c for 500 ml

B] $2 for 2L

Clarify: I don’t have anything to clarify.

Mathematician’s Toolbox: ‘Have I seen a similar problem?’.

What’s the BIG question? Which deal out of A or B costs less.

Working out: Before I worked this out I went well 500ml is one quarter of 2L so I knew that if it was B every 500ml would be 50c because that is a quarter of 2L. In A though it costs 75c which would be 25c more then B. If you times 75 times 4 it is $3 so it would be more then B.

Summary: The answer I got B and it was not hard at all.

Maths Mate Sheet 7 Term 4

Predict: I predict that this will be about quantities and money.

Read: Which deal costs less?

A] $32 for 4 L

B] $8.50 for 1 L

Clarify: I have nothing to clarify.

Strategies/Mathematicians Toolbox: ‘Have I seen a similar problem’

What’s the BIG question? Which deal costs less?

Working out: Well I knew that 8 is a quarter of 32 and it is offering a quarter less amount of L for B but it is $8.50 and that is not a quarter of 32 so if you want 4 L for $8.50 each it will come to a price of $34.00 and the other one is $32.00 for 8 L.

Summary: I believe that A is the correct answer. We had a similar problem last week so I used the way I worked out that to work out this problem.

Maths Mate Term 4 Sheet 6 Question 23

Predict: I predict that this might have to do with problem solving because when I looked at it, the problem was lengthy.

Read: When Tony has his birthday tomorrow, his age in months will be the same as his grandfather’s age in years. How old will Tony be if their combined ages will be 78?

Clarify: I have nothing to clarify about the problem.

Strategies/Mathematicians Toolbox: ‘Try all possibilities’, ‘Try a simpler problem’.  If you would like to look at the list of them here is the link:

http://amelia2012.global2.vic.edu.au/maths-tool-box/

What’s the BIG question? What age will Tony turn tomorrow?

Working out: I know that there is 12 months in a year and his grandpa’s age is in Tony’s months. Firstly I knew that I will have to try some numbers and times them by 12 then takeaway the number I times by 12  then add onto 78. Whatever the answer to that is should equal the amount of months Tony has lived for as this is the grandpa’s age. I firstly tried 12. I times that by 12 which equals 144 but the grandpa is not 144 because Tony’s and his grandpa’s combined ages are 78. Next I tried 5. So I did 5×12 which equals 60 so if this was the right answer the grandpa would be 60 and Tony would be 5 so I would add that together which is 65 but there combined ages are 78 but I was close. I tried 6. 6×12=72 so grandpa would be 72 and Tony would be 6 so 72+6 is 78 which is the combined total of their which that was it so that is the correct answer!

Summary: This question I found hard because it took me a lot of guess’s to work out. I finally got there and Tony’s that he will be turning tomorrow is 6.

Maths Mate Sheet 5 Term 4 Question 22

Predict: I predict that this problem will be about weight and quantities of things.

Read: Which deal costs less per gram?

A] $5 for 500 grams

B] $3 for 250 grams

Clarify: I have nothing to clarify.

Strategies/Mathematicians Toolbox: ‘Prior knowledge’, ‘Work it out backwards’, ‘Try a simpler problem’. If you would like to look at the list of them here is the link:

http://amelia2012.global2.vic.edu.au/maths-tool-box/

What’s the BIG question? Which costs less: A or B.

Working out: Firstly I went well if it costs $5 for 500 grams then for every $1 you get 100 grams. With B I knew that A was cheaper because for every dollar in B you get less than 100 grams for $1  but in A you get 100 grams for $1.

Summary: The answer I got was A. I used strategies to help me work it out and with the prediction I did have to use some things to do with weight and quantities but also comparing numbers and weights together.

Maths Mate Term 4 Sheet 4 Question 22#

Predict: I think that this problem will be some sort of number problem and may involve division or division skills.

Read: Fill in the missing number 36 divided by ? equals 4.

Clarify: I have nothing to clarify.

What’s the BIG question? What is the missing number in the equation?

Strategies/Mathematicians Toolbox: ‘Write an equation’ and ‘Prior Knowledge’. If you would like to see some for strategies click on the link: http://amelia2012.global2.vic.edu.au/maths-tool-box/

Working out: The way I  worked this out was that I knew from my prior knowledge that 9×4=36 and if I changed it around to 36 divided by 9 it would equal 4!

Summary: The answer is 9 which fits into the equation perfectly. My prediction was correct and I used the strategies I said but not that much of the ‘write an equation’.

Maths Mate Term 4 Sheet 3

Predict: I predict that this question will be a word problem because of all the words.

Read: A bookshop sold 200 books over the internet in its first year of business. Since then the sales have doubled every year. What was the bookshop’s profit in the sixth year given the yearly profit formula below.

Yearly profit=books sold x$2-$1000

Clarify: Nothing to clarify.

Strategies: Write an equation, Break the problem down.

What’s the BIG question? What is the bookshops yearly profit?

Working out: Firstly I did well if they sold 200 books and it was 6 years selling and there amount doubled each year they would get over 6 years:  6400. Then with the formula you would have to times it by 2 [$2] which would give you 12 800. Then take away 1000[$1000] which is 11 800.

Summary: My answer is $11 000 I found this problem challenging and I got confused a bit. The strategies I used helped me

Maths Mate – Term 4 Sheet 2 Question 22

Predict: I predict that this will be a number sum with division in it.

Read: Fill in the missing number.

Something Divided by   5  =  9

Clarify: There is nothing that I need to clarify.

What’s the BIG question? What is the missing number?

Strategies/Mathematicians Toolbox: Prior knowledge, Work Backwards, Have I seen a similar problem?

Working Out: All you need to do to work it out is [this is what I did] work backwards and go well 5×9=45 so 45 divided by 5 equals 9. I also knew my number facts and times tables.

Summary: The answer was 45 and it was a simple number fact that you had to know to work the sum out!

Maths Mate Term 4 Sheet 1 Question 22.

Predict: I predict that this problem will be about multiplying because when I had a glance at it, it was a multiplication problem.

Read: Fill in the missing number.

12 x   ?  = 36

Clarify: I have nothing to clarify.

Mathematicians Toolbox/Strategies: I am going to use my prior knowledge work it out.

What’s the BIG question? What is the missing number to complete the equation?

Working out: To work it out I simply went well if the answer is 36 and it is something times 12 I knew that 12×3 is 36 so that fits in there.

Summary: The missing number was 3 and all I did was use my prior knowledge because I knew my times tables.

Maths Mate Term 3 Sheet 8 Question 22

Predict: I predict that this problem will be about addition because having a quick glance at it I could see a simple addition problem that had numbers missing.

Read: Fill in the missing digits in the sum. This is a vertical addition sum.

17

– –

+  36

—————–

95

Clarify: When reading I had no words, phrases or sentences to clarify.

What’s the BIG question? What are the missing numbers.

Mathemations Toolbox Strategies: ‘Have I seen a similar problem?’

Working Out: Firstly I started with the first colon which was 7+6 but that equals 13 and I want it to equal 5 so I knew it would have to be 15. I went well how much more to get to 15 and I knew it was 2 so I put that there. Next I moved onto the 2 colon and regrouped the 1 from the last colon I did. I knew it had to equal 9 and the numbers there were 1+3 and the extra 1 which is 5. Another 4 would make it 9 so I put that there.

Summary: My answer is 42. The whole sum is 17+42+36=95! I think that like very week it was easy and a I have been learning how to do that a lot.

 

Maths Mate Term 3 Sheet 7 Question 22

Predict: I predict this problem will be about addition because in the picture it had an incomplete addition sum.

Read: Fill in the missing digits in the subtraction. _9 – 5_ = 23.

Clarify: I have nothing to clarify about this problem.

Whats the BIG problem: What are the missing problems to complete the sum.

Mathemaitions Toolbox: ‘Have I seen a similar problem’.

Solve: To solve this problem wrote it out as vertical addition. I went well what is 9 take away somthing that equals 3 and i knew it was 6. Then I did the next column and went what take away 5 will give me 2 and I knew 7-2 is 5 so I put the 5 there.

Summary: The answer is 79-56=23. To make sure I did the problem backwards. It was easy and I because last week we had a similar one.
