All sites listed on this page have a substantial number of resources available for free. The names of each website are included so that, even if the links expire, an Internet search on the website name can be used to locate the site.
Libraries for Teaching Specific Math Procedures
The following sites contain libraries of videos (and sometimes other material) designed to teach specific procedures, such as adding fractions or converting a decimal to a percent. They are excellent resources to share with students.
- Khan Academy: https://www.khanacademy.org/
- Patrick JMT: http://patrickjmt.com/
- Math A Tube: http://www.mathatube.com/index.html
Interactive Math Software
GeoGebra is a software program designed to let students experience the natural connections between geometry and algebra (hence the name!) However, it should be noted that this resource extends down to the early primary grades—long before students enroll in an official class in geometry or algebra. It is now also possible to work on data and statistics as well as 3-D geometry in GeoGebra.
- The main GeoGebra site, including links to a free download can be found here:
- GeoGebraPrim is a version of GeoGebra tailored for primary students and can be downloaded here:
- A library of informational videos on exercises and activities for GeoGebra at any level can be found here:
Online Graphing Calculator
Desmos offers a free interactive calculator. At its simplest, it can be used as a four-function, scientific, or graphing calculator. Later, as students begin to encounter basic equations and more advanced algebra, the calculator offers many visual options for exploring math relationships. The calculator can be found here: https://www.desmos.com/
Everyone gets bored doing repetitive drills of math problems. While procedures are important, it’s also a good idea to expose students to “real” math that involves creative thinking and problem solving. Here are some sites that offer a variety of math puzzles:
- Stella’s Stunners (these puzzles officially begin at the pre-algebra level, but many do not require formal math knowledge to solve): http://ohiorc.org/for/math/stella/library/bycourse.aspx
- Math is Fun Puzzles: http://www.mathsisfun.com/puzzles/
- Syvum Math Brain Teasers: http://www.syvum.com/teasers/
