Numbers and Arithmetic
- A variety of fraction lesson plans and teaching ideas.
Data and Statistics
Puzzles, Games and Mathematical Art
Multiplication by Heart
Multiplication by Heart flashcards use the principle of spaced repetition to help students learn multiplication facts. Made in partnership with Dan Finkel at Math for Love, each multiplication fact is presented with a concrete visual representation. Create a Mathigon class and track student progress.
Mathigon has a variety of other activities for exploring mathematics.
When playing Factris, students use their knowledge of factors of whole numbers to earn high scores and eliminate as many whole rows as possible.
While Tangrams are one of the many virtual manipulatives on Polypad, Students can also visit the custom Tangram Activity to use tangrams to create a wide variety of pictures.
Timeline of Mathematics
Students can learn about mathematicians and mathematical artifacts on the Timeline of Mathematics.
Since 2017, Mathigon has published a puzzle calendar during the month December. The “easy” and “1-star” puzzles are appropriate to use with 6th through 8th graders.
Social Distancing Puzzle
In the Social Distancing puzzle, students must move the other shoppers around the store to make it to the exit.
The video below provides an overview of the interactive nature of the Mathigon Courses. Some of the animations in the Middle School course might help middle school students understand important mathematical concepts and ideas. The High School courses include some more-advanced content that can be used by students looking for enrichment and additional challenges in math class.
