We hope that what we teach our children sticks with them, and that they build on that knowledge for the rest of their lives. But traditional approaches to education often fail to help children retain the material. Short units that focus on good test performance succeed in short-term retention, but do not result in learning that sticks with students long after they’ve finished the unit. However, different approaches that emphasize mastery of concepts help students retain material longer. Two dominant approaches for learning that sticks, specifically in math, are mastery and spiral learning. These learning strategies are tools you can use to choose and adapt curriculum to best support your children.
