Play with numbers and give your brain a workout

Contains numerous manipulatives organized by grade bands and content strands. A must-have for every math teacher!

Quick Summary: A digital library containing Java applets and activities for K-12 mathematics Elongated Explanation: The National Library of Virtual Manipulatives (NLVM) is an NSF supported project that began in 1999 to develop a library of uniquely interactive, web-based virtual manipulatives or concept tutorials, mostly in the form of Java applets, for mathematics instruction (K-12 emphasis). This site should be used frequently with students to explore and expand on many different levels and mathematical concepts. Learning and understanding mathematics, at every level, requires student engagement. Mathematics is not a spectator sport. Too much of current instruction fails to actively involve students. One way to address the problem is through the use of manipulatives, physical objects that help students visualize relationships and applications. We can now use computers to create virtual learning environments to address the same goals with sites like this one. APA Citation: Cannon, L., Dorward J., Heal R., & Edwards L. (2007, July 28).

Growing pattern activities for algebraic thinking

Students must open and close lockers by following a pattern in order to determine how many will be open/closed at the end of the activity. Includes a virtual set of 100 lockers for trial-and-error.

Grade level and content strand activities

Activities for the TI calculators

Game that allows students to find the prime factorization of a number. Assists students by giving them one factor when they correctly identify the other.

Short how-to audio lessons.

Virtual Math Field Trips

Basic algebra explanations

Math Playground is a great website and includes many math games. The "Function Machine" game is a great resource for students to investigate the relationship between the input and output values of a function. Students are able to explore developing patterns and identify these patterns in this function machine game. Depending on your students understanding of functions there are different levels to this game, level one are simple, one step functions using the four basic operations, level two consist of two step functions, and level three consists of a mix between one and two step functions with larger values and some decimal outputs (which also allows from differentiation).
