Magic Star Puzzle

Subject: star puzzle

I am in 7th grade and need help with my first homework assignment.  I 
have a star puzzle. The star is shaped like 2 triangles.  There are 
circles at each intersection and the points of the star.  There are 4 
circles in each row.  We have to use the integers 1 to 12 and the sum 
of each row must be the same.  I have worked on it since Friday and my 
parents have tried to help too.  Can you help me?  CM

Hi CM -

The Math Forum has a Web unit on Magic Squares by Forum Teacher 
Associate Suzanne Alejandre, within which there are some "Magic Star" 
pages by Japanese Professor Mutsumi Suzuki. See:   

The Magic Square Web unit is at   

People love to think about the math in these historical 'puzzles'
and you'll find many explanations of the math involved in
these pages.

Good luck with your homework!

Dear Dr. Math,

Thank you for your help and the Magic Star site!  How did you figure 
it out?

Hi -

Those 'Stars of David' were contributed by a Japanese professor, 
Mutsumi Suzuki, who came up with eighteen of them while traveling 
home on the Shin-Kan-Sen (Japanese bullet train).  Later he found a 
1992 book (in Japanese) about magic squares by a high school teacher 
named Kiyomi Omori that mentions magic stars and inspired him to work 
out two more of them.
