1001 Math Problems

1001mathproblems.com features resources that focus on mathematical reasoning and problem solving. The problems are aimed at Key Stage 3, though many of them would also lend themselves to Key Stage 2. The work is presented here in the form of printable materials with links to the original website to provide colour presentations.

The materials are the creation of Sian Zelbo, associate director of the Centre for Mathematical Talent at the Courant Institute of Mathematical Sciences, New York University. Sian also teaches at a high school and works as a math education consultant with various other schools in New York City.
