✦ The Book

For every parent who said
"I was never a math person."

You don't have to be a math whiz to help your kid with math. You just need someone to translate — and that's exactly what this book does.

Math for Parents: Elementary Edition walks parents through the concepts their kids are learning, in plain language, with real strategies you can use at the kitchen table tonight.

A note from Tammy: This edition is real and it works — and a revised edition is in the works. You're not getting a rough draft. You're getting the book that started a movement, written by a teacher who's been in those classrooms.

✦ Handmade Games

Math you can play.

There's something different about a physical game. You pick it up, you set it down, you play it with someone across a table. Screens off. Thinking on.

The Mathematic Tac Toe board brings a beloved math classroom game into a real, handmade play space. Each board is made by Tammy — not manufactured, not mass-produced. Made.

✦ A note from Tammy
"Everything in this shop exists because I believe math belongs in your hands, not just on a screen. The games, the art, the book — they're all ways of saying: math is worth making something out of. I hope one of these finds a place in your home."
— Tammy Reeves, M.Ed. · Founder, Flippin' Math
