QUESTION 24: Fill the big square so that each row and each column contain the numbers 1,2,3 and 4. The digits within the thicker outlined area, when combined using the given operation, must equal the given number.

PREDICT: I predict that I will have to use my problem solving skills and use numbers.

SOLUTION:

1. First in the 8x thicker outline you put 3 numbers that are times together to make 8. The top left corner is 1, next to 1 is 4 and 2 under the 1.

2. Then do the thicker outline fo 7+. The numbers is 3 at the top and 4 underneath,

3. Now do the 6x thicker outlined part the 2 at the top and 3 underneath.

QUESTION 23: The digit sum for 195 is 1+9+5, or 15. The digit sum for 200 is 2+0+0, or 2. find the 2 consecutive numbers that have digit sums of 27 and 1.

PREDICT: I predict I will have to use multiplication and consecutive numbers.

SOLUTION:

1. Think of what is 27 divided by 3. the answer is 9.

2. so you would write 9+9+9.

QUESTION 22: Move 2 matches to leave 4 squares. PREDICT: I predict that I will have to SOLUTION: 1. First you have to find a place where you can move 2 matches. I chose the one under the 3^{rd} square. 2. Now you have to move 2 of the matches. 3. This is the matches I moved to make 4 squares. SUMMARY: The strategy I used was to do a before and after pic and figured out which way to go.

2. Add what the Family of 4 and an extra child. $ 79.00 + $15.40= $94.40

the answer is $3.80

SUMMARY: The strategy I used was the 4 operations.
