My daughter is in 2nd grade and has a worksheet called Magic 26. It wants her to use the numbers 1 12. Each row, column, and diagonal must equal 26. The four corners and four center numbers must equal 26 too. (example of puzzle below) Please help solve. THANKS!!!!!

This is the third time you have posted this question since last night. If someone could help you, you'd have been helped already. Please stop posting the same question, over and over.
If there is a math tutor who can help you, he/she will. Please be patient. 
The requirements you spell out do not enable the derivation of a normal magic square. Normal squares have 9, 16, 25, 36, etc. squares using the given digits once. For instance
816
357
492
all rows, columns and diagonals adding to 15 or
115144
12679
810115
133216
all rows, columns and diagonals adding to 25.
While your square appears to have only 12 digits, I think you would be hard pressed to have them arranged so that they sum to 26 when the normal magic square using 16 digits of 1 through 16 adds to only 25. If a digit can be used more than once, perhaps that opens the door to possibilities. It would appear that you have a guess and check game to play here. 
i need help on home work

Pg 25

From 1 to 12, we have six pairs with sum of 13. (1,12), (2, 11), (3, 10), (4, 9), (5, 8) and (6, 7). Sum of two pairs will be 26. Therefore, playing around with these pairs. Here is the answer:
1 9
5 10 2 7
8 3 11 6
12 4 
Rearrange number again
1  9
5  10  2  7
8  3  11  6
12  4 
Rearrange for correct answer:
1  9
8  10  2  6
5  3  11  7
12  4
