Playing games can be a fun way for students to practice and develop their knowledge of basic facts. If you are looking for some mathematics games for your students, these are five sources you may want to explore.

1. Learning Games for Kids offers games for mathematics as well as many other content areas. Most of the games on Learning Games for Kids can be played directly on the website although some do link out to other sources.

2. Learn With Math Games is a site that I like because it offers online games as well as PDF templates for games that teachers and students can play in their classrooms. Learn With Math Games is organized by grade level and by mathematics topic.

3. Maths Week 2009 is currently underway in New Zealand. On the Maths Week website, developed by Etraction, you will find fun and challenging mathematics games. Most of the games deal with money and finance.

4. Gamequarium developed by Diana Dell (a great person to follow on Twitter by the way) offers an excellent catalog of mathematics games and video demonstrations of mathematics functions.

5. Primary Games offers a collection of mathematics games as well as games for other content areas. You can grab some of the games on Primary Games and embed them into your own blog or website.
