H is for . . .

I'm posting Mad-Cool-Math nuggets this month.

H is for a Hamiltonian Graph.

There is a branch of mathematics called Graph Theory and, in this case, graphs are not bar graphs or line graphs. They look like a bunch of dots, some of which are connected by lines. Dots are called vertices and the lines are called edges. You're learning college-level math now, isn't it awesome?

Don't get too excited. This type of math is done in kindergarten classes all the time. How? Well, in a Hamiltonian Graph, you can forge a path along the edges that will pass through each of the vertices exactly once. Ready?

Make a Hamiltonian path for this graph:

Congratulations! I knew you could do it.


Two more days to go on the free download of the novella Ursa Major. Response has been good, so thank you. And next week? There will be a different freebie. Stop by then for details.


  1. This was about the only type of graph I liked. HAHA! :D

  2. Ha-ha. Now this is a graph I can handle!

  3. This type of graph has more imagination to it than the standard boring lines. It seems like a fun way to teach math to children.
    Thanks for stopping by the UR blog today!

  4. I, too, found this type of graph very user friendly... and there was nothing fishy about it :)

  5. I never knew I was learning college level maths when I used to do my dot to dots!

  6. All these years I didn't know I was actually Hamiltonian Math, not connect the dots.

    Thanks for commenting on my blog!

    1. Join the dots. Now that's the sort of maths I can handle.

    2. Join the dots. Now that's the sort of maths I can handle.

  8. Joint the Dots. Now that's the sort of maths I can handle.

  9. Copied it, printed it, joined the dots and coloured it in! I am now craving fish and chips!

  10. Haha, I didn't even know that was what it was called! You learn something new every day!

I will do everything in my power to visit commenter's blogs unless I've been abducted by aliens or my children get sick. (If my children get abducted by aliens, I will be very busy, of course, catching up on my sleep.)
