This poster was created by and for mathematicians, teachers, children, and parents. What is multiplication all about? Why is multiplication useful, beautiful, and fun? The twelve fundamental models address these questions. Each model tells its own multiplication story that comes with two clear illustrations, example formulas, and short activity prompts. It is an intriguing invitation to spend hours exploring rich mathematics.
NOTICE: As of 2023, we only deliver the paper posters within the USA. We are working on delivering internationally again. Meanwhile, our math friends overseas could use the electronic version.

We love to read notes from participants explaining why they join, so here are a few:
We give you lots of ideas for adapting them for younger (ages 3-5) and older (13+ ) children. A single activity can take you as little as 10 minutes or as long as a couple of hours, depending on how much your child and you get into it.
Multiplication Explorers invites you to master holistic approach to learning multiplication. Memorization based on smart number patterns is a part of it. The course also includes bridges between multiplication and natural world, as well as links to many virtual and imaginary worlds in books, music, technology, art, and games.
