Re: Mistake in Level E Lesson 3?

Ok. So I got this figured out, but I'm hoping the 2nd version of this has better instructions for it as it was really confusing.

Re: Mistake in Level E Lesson 3?

Hi, Jess. My name is Rachel and I am happy to help you today.

Hmmm...I have different numbers in the corners than you have listed. Let me write out what my manual has for magic square number 3:

16 23 42 19
54 10 11 25
19 59 20 2
11 8 27 54

When I add the numbers together horizontally, vertically, diagonally and the corners, I get 100.

I find that number 4 also works. Here are the numbers listed in my manual:

18 24 15 -7
-11 19 11 31
11 14 6 19
32 -7 18 7

I hope that helps! If you have any further questions, feel free to re-post here or email RightStart Math directly at

Have a fabulous day!
