"Mathigon provides a series of free, interactive, online courses that are designed to complement 6th grade through college level mathematics instruction. The website was founded by Philipp Legner, who studied mathematics at the University of Cambridge and mathematics education at the London School of Economics. Legner, who currently works at Google, wanted to design a website that enabled learners to examine mathematics concepts by actively engaging in problem solving. Each course explains key concepts and skills through a series of short explanations, helpful visualizations, problem sets, and quizzes. Learners receive feedback as they work their way through each course. Visitors to this website can find courses by browsing through the course library, which sorts available courses by grade level (6-9; 10-12; College, Fun and More) and by topic (Geometry; Functions and Equations; Probability and Statistics; Calculus and Mechanics; Applied Mathematics, etc.)."
Problem solving is the heart of mathematical learning. This site complements existing curricula by providing a resource for teachers who use, or are only beginning to use, a problem-centered approach. This resource will also help parents and tutors support problem-based learning in out-of-school settings.
This site provides an extensive collection of free resources, math games, and handson
math activities aligned with the Common Core State Standards for Mathematics.
Our math printables are suitable for use in math centers, small group or whole class
settings. Instructions for each activity are presented in large print on a task card in
child-friendly language to enable students to work on tasks independently after a brief
introduction to the task.
All materials and activities on the site are designed to support the Common Core
State Standards and are based on the belief that effective mathematical learning is
best achieved when students are given frequent opportunities to develop their own
problem solving strategies, to pose questions, and to engage in mathematical inquiry
through the use of open-ended tasks.
