Maths Mate: term 4, week 3.

problem 24: a bookshop sold 200 books over the Internet in it’s first year of business. since then sales have doubled every year. what was the bookshops profit in the sixth year given the yearly profit formula below?

yearly profit= books sold x $2 – $1000

predict: I predict that I will have to use multiplication in the sum.

clarify: I have no words, sentences, or phrases to clarify.

find the big question: what was the profit?

solve:

first it said that the sales have doubled every year, and it has been running for 6 years. so, to make sure I did it correctly I went down in a list.

1- 200

2- 400

3- 800

4-1600

5-3200

6-6400.

next we times it by $2. which is: $12,800

now we have to take away $1000, which is $11,800!

the answer is $11,800

summary: the mathematicians toolbox strategy are used in this sum was break the problem into manageable parts.

problem 22: fill in the missing number.

__÷5 = 9?

predict: I predict I will need to use multiplication in his sum.

clarify: there are no words, sentences or phrases that I need to clarify.

find the big question: what is the missing number?

solve:

this problem was very simple to do.

first I worked out what 9×5 was, and that was 45!

to double check, 45÷5=9!

the answer is 45.

Problem 23: Fill in the magic square. (Hint: every row, column and diagonal has the same sum.)

4    
  6  
  1 8

 

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

Clarify: I have no words, sentences or phrases that I need to clarify.

Find the big question: What are the missing numbers?

Solve: First, I need to work out what 4+6+8 equals. It equals: 18.

So, now I need to make every row, column and diagonal equal 18.

First I will start with 6 and 1. That equals 7, so I need 11 more to get to 18.  So I write in 11 above 6.

So now I have 11 next to the four, and added together that equals 15, and I need 3 more to get to 18. So I write 3 next to 11.

Now I’ve got another row with 2 numbers. 3 and 8. That equals 11, and I need 7 more to get to 18.

Now I have a 6 and a 7, and that equals 13, and I need 5 more to get to 18.

Finally, I have a 4 and a 5 which equals 9, and there needs to be another  9 to get to 18.

4 11 3
5 6 7
9 1 8

 

Summarize: the mathematicians toolbox strategy I used in this sum was break the problem into manageable parts.

Problem 23: I think of a number, multiply it by 3 and divide it by 2.  If the result was 18, what was the original number?

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

Clarify: I have no words, sentences or phrases to clarify.

Find the big question: what was the original number?

Solve:

  1. this sum is a little bit different than others I’ve done.
  2. first, I started with trying 18 / 2 x 3,thinking that definitely wouldn’t work.
  3. But then, I checked it and the answer was 24. But 24 x 3 /2 isn’t 18. It’s 36!
  4. So I tried 18 / 3 x 2.
  5. That was 12.
  6. So I double checked it; 12 x 3 / 2 and it was 18!

the answer is 12.

summary: the mathematicians toolbox strategy I used in this sum was use my prior knowledge.

finally we can make a start!

Ugh. We’ve been waiting for this food forever. When will it finally come? This is a nightmare!

Yay! The food came. Finally we can make a start! I bit into the chip, the soft, filling chip, and, and…. ewwww! That is disgusting! It tasted like seafood mixed with yuck! we waited all this time for this. That is just unbelievable. Well, let’s hope the main is better.

My pasta came! It certainly looked better that the chips. I took a big spoonful… and I’m disappointed once again. Is it really that hard to make chips and pasta? Just plain pasta with Napoli sauce. Is it that difficult?

Problem 22: Fill in the missing digits in the sum.

16

__

+51

_________

96

 

Predict: I predict that I will need to do addition in this sum

Clarify: I have no words, sentences or phrases to clarify.

Find the big question: What are the missing digits?

Solve:

  1. Well, 6+1 cant equal 6, so it has to equal 16.
  2. 6+1=7. 7+?=16? 9.
  3. So we write down 9 and carry the one.
  4. Now, 1+ the carried 1= 2. So, 2+5= 7, but 7+?=9? 2.

The answer is

16+29+51= 96.

Summary: The mathematicians toolbox strategy I used in this sum was break the problem into manageable parts, and use my prior knowledge.

Maths mate: Term 3, Sheet 5

Problem 23: I think of a number, divide it by 2 then add 12. If the answer is 20, what was the original number?

Predict: I predict that I will need to use subtraction in this problem.

Clarify: I have no words, sentences or phrases to clarify.

Find the big question: What was the original number?

Solve:

  1. Since I have to reverse the process, because I have to find the original number, we will reverse the operations too.
  2. The equation that they did was: __  / 2  + 12 = 20. But since we are reversing it we are doing subtraction and multiplication, because they are the opposite operation.
  3. The equation that w are doing is: 20 – 12 x 2 = 16.

The answer is 16.

Summary: The mathematicians toolbox strategy that I used in this sum was work backwards.
