### The Most Popular Math Games On This Site

By

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!

Why not 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! How soon does your name appear? Viewed 1842 times...
In the Magical Calculator Birthday Trick and the "Threes" Math Trick, one child gives a sequence of arithmetic instructions to another, then performs a few simple mental steps on the result.

This site has worksheets to help kids work through a Modern Rice-And-Chessboard Story and see for themselves how rich the reward was. Viewed 949 times...
"What is it?" It's a Tizit!! A Tizit is an impossible figure, an optical illusion. On this site, I've uploaded 30 Tizit puzzles designed by retired math teacher Mac Oglesby. Download a Tizit, and you'll see a scattering of labeled dots, and instructions showing which ones to join. Join the dots carefully with a ruler, and an amazing, eye-twisting figure will appear. Get your kids to draw and color a Tizit now, then send me a copy of their mathematical artwork, so I can make a gallery of Tizits on this website! Viewed 446 times...
A 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. Viewed 432 times...
Alice Oglesby's Cross-Number Puzzle is actually a crossword puzzle - but the clues are all arithmetic sums. How is that possible?

The Upside-Down Calculator Word Game is recommended for kids in fifth grade and fourth grade, and maybe also third grade.
