You've come to this site looking for really great math games and resources to help kids with math. So which ones are the best? It's hard to say, of course. Each person is different. At the same time, we've all got something in common. Stuff other people like, we also usually like.

So, if you want to find out the best games on this site, it makes sense to ask what other people like best. This page shows the most popular games on this site. When I say popular, I mean according to how many times people visit the game web page. There's a different page that shows which games people rate the most highly.

Some of the games and other resources on this list get popular because Google thinks it's good. Others are there because lots of people are searching for it. Some weeks a game that's normally missing from the list will pop up because of hits from some social network or social bookmarking site. In each of these cases, you can be sure that the game is a good one.

There are, of course, dozens of other great games and resources that don't make it onto this list. So be sure to spend some time as well exploring the site, starting with the menu in the sidebar.

And now for the list of the most popular games on this site over the past week!

**Find Your Name In Pi**? When we write pi=3.14159.., we use our normal ten different digits, which we call 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. I converted pi to base 27, and called the digits <space>, A, B, C, ..., Z. That way, the digits of pi become a long list of letters. I've got 31 million base 27 digits, I've put them on my webserver, and I've made a search box for you to use!

**Magic Hexagon Worksheet**is just like a magic square worksheet - students need the same set of skills to solve each one - the difference is that most students will never have seen a magic hexagon before. This website has a Magic Hexagon Worksheet Generator that lets you generate randomized magic hexagon worksheets

*with the answer key*. The worksheet will be different each time you come back to this site, so you know there's no way for students to drop by themselves and cheat by downloading their own answer key.

**Alice Oglesby's Cross-Number Puzzle**is actually a crossword puzzle - but the clues are all arithmetic sums. How is that possible? Once you've worked out each sum on a calculator, you turn your calculator upside down, and each number becomes a letter. You can download and print Alice's puzzle, solve it, and then make your own upside-down calculator cross-number puzzle with the help of the long lists of calculator words linked from

**The Upside-Down Calculator Word Game**is recommended for kids in fifth grade and fourth grade, and maybe also third grade. Younger children may find it too challenging - although my son's grade one teacher recently gave an exercise like this one to her class! The aim is to find numbers that make words when keyed into an upside-down calculator. See the game's page for more details.
