soloution:

1.this was so easy

2. so first i had to figure out what takeaway9 equals 3 easy 6

3. 5 – what equals 2

4. 3

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:

Well, 6+1 cant equal 6, so it has to equal 16.

6+1=7. 7+?=16? 9.

So we write down 9 and carry the one.

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 knowlee.

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 use subtraction in this problem.

Clarify: nothing to be clarified

Find the big question: What was the original number?

Solve:

Since I have to reverse the process, because I have to find the original number, we will reverse the operations too.

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.

The equation that w are doing is: 20 – 12 x 2 = 16.

The answer is 16.

Summary: The math maticians toolboxthat I used in this sum was work backwards.

Problem 22: The sum of four consecutive numbers is 94. What are the four numbers??

Clarify: nothing to be clarified

Find the big question: What are the four numbers?

Solve:

I was very confused about how to solve this problem, but I worked out that I was over thinking it.

First I divided 94 by 4 which equals 23.5

That means that 23.5 is the middle number in the sum, because of the .5.

So at first I didn’t realize that 23.5 had to be the middle number so I did 21+22+23+24, but that made 90.

So that means the 23 has to go in the middle, so I chose 22+23+24+25=94!

The answer is 22,23,24 and 25.

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

Problem 22: The sum of three consecutive whole numbers is 96. What are the three numbers?

Predict: I predict I will need to do addition and division in this sum.

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

Find the Big Question: What are the three numbers?

Solve:

- First I knew that 3,3 and 3 added up to 9.

3

2. Then I knew that 1,2 and 3 add up to 6.

31

32

33.

3. Then I double checked to see if it was right. Yes!

The answer is 31, 32 and 33.

Summary: The mathematicians toolbox strategy I used in this sum was use your prior knowledge.

Problem 22: 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?

Predict: I predict I will need to use division and addition in this problem.

Clarify: nothing to be clarified

Find the big question: What are the page numbers?

Solve:

I need to start by splitting 333 in half, because they need to be consecutive. Picture a book, the page numbers are consecutive,, aren’t they?

It is 166.5 but I will round that up to 167.

167+168=335.

So I will round down to 166.

166+167=333!

Summary:

The mathematicians toolbxo strategy I used in this problem was break it into controllable parts.

Problem 22: The sum of two consecutive whole numbers is 97. What are the two numbers?

Predict: I predict that I will need to use division and addition in this problem.

Clarify: nothing to be clarified

Find the big question: What are the two numbers?

Solution:

The first thing I did was divide 97 by 2= 48.5

but they are consecutive whole numbers.

So I rounded up to 49. But 49+50=99, not 97.

So I rounded down to 48. 48+49=97!

TERM 2 SHEET 6

PROBLEM: each letter represents a different digit from 1 to 9. if R=8,what number does four stand for

Prediction: I think that this will involve subtraction

STEPS:

- So its pretty easy all we need to know is the alphabet .
- So this means that ay like 8 = R so all you need to do is count backwards in the alphabet
- So let’s give it a go
- 7=Q
- 6=P
- 5=O
- 4=N …
- YAY and you have your answer

Solution: so all you needed to do is use a pattern and stick with it this problem ivolved subtraction

Another problem solved by buzz bee 🙂

enter the numbers in the circles so that the numbers on each line equal the sum of the numbers at each end

problem: I think that this will involve allot of addition and division

clarify: nothing to be clarified

1. so how it looks is like this in the middle in the lines on the left hand side is the number 43 and the number on the right hand side in the middle is 55 and at the very bottom in the middle it is 30

2. so i first had to figure out what plus what equals 43 i had only one answer 2 which was 22 +21

3. so then I had to do the same with 55 so i got 21 +34 and 22+33

4. and then i had to do my last number 30

so I got 15 +15

5. so I tried at my first attempt i put 15 on the left side on the bottom and then i put the other 15 on the other side across from the thirty on the right hand side and then i put the 21 on the top

6. now that is absolutely wrong

7. so then I tried 21 at the top 34 at the right hand side at the bottom and across from thirty on the left hand side is 9

8. AND THEN IT HIT ME

9. it doesn’t work so then i decided to switch the 34 and the 21 and it worked

10. so in the end it should end up like this at the very top 34 in the middle on the left hand side is 43 the on the very bottom of the left hand side is 9 across from the 9 in the middle of the bottom line is 30 then across from 30 is 21 and above 21 is 55 and leaves us too 21 on the very top.
