One of my teammates was telling me about a website where you can create basic math facts puzzles.
All you have to do is enter in a greeting and it generates a puzzle for your students to solve. I thought it would be a great activity for students to do for homework. I can see my students enjoying solving these math puzzles. Anyway to get them to practice their math facts works for me.
Here's an example of one I completed. I believe this puzzle says "Practice Your Math Facts Every Night". or something like that.
Here's the link to the site.

There are a lot of other worksheets that you can generate. The best part is that it is for free.
Have fun looking around.
