Comfortable enough for busy school days and made for educators who are proud to show off their love for Math Stackers® and hands-on math.

Please note: Math Stackers® Merch is made to order and fulfilled separately from our Math Stackers® products, so merch may arrive in a separate package. Merch is available for online purchase only and cannot be purchased using a purchase order.

Please check the sizing chart in the product images before ordering. This is a unisex tee with a classic, regular fit. For the best fit, compare the measurements in our size chart with a favorite T-shirt you already own.

Because each item is made to order, merch is final sale and cannot be returned or exchanged for sizing, color, or change of mind. If your item arrives damaged, defective, misprinted, or different from what you ordered, please contact us within 30 days and include a photo of the issue so we can make it right.
