Welcome to Math Playground, an action-packed site for elementary and middle school students. Practice your math skills, play a logic game and have some fun!
Math Playground was created by teachers who are passionionate about math and technology. Many of the activities on the site were inspired by the hundreds of students we have had the pleasure to teach over the years. Other activities have been provided by generous educators and programmers who share our passion for making learning fun. Math Playground is not affiliated with any school, business, or organization.
