Mama, her toddler, and two stuffed bunnies turn a grocery store outing into an opportunity to talk, laugh, and learn a little math. As they fill their cart with items in quantities of one and two, Mama lets her baby hold them, connecting the familiar idea of one and two hands to concepts of one and two. This material is based upon work supported in part by TERC under a grant from the Heising-Simons Foundation.
