In October of 2017, the Collaborative hosted Promising Math, a conference meant to link the research, practice, and policy arms of early mathematics. This forum is a furthering of the mission of that event, with the goal to extend the thinking and learning that took place.
The Mathical Book Prize is an annual award organized by the Mathematical Sciences Research Institute (MSRI). With an aim to "inspire a love of mathematics in the everyday world in children of all ages," the winners…
Teachers in four schools recently experimented with a "problem stem" protocol for helping their children understand the math going on in the word problems they face in class. This was part of our Big Shoulders…
Long before young children are writing equations with the equal sign, they are exploring how amounts that look different can actually be equivalent.
