Online tools for learning and practice can be fun and useful to supplement a rich, interactive math curriculum. However, learning is a social endeavor and students learn to become mathematically fluent by doing real math, solving problems in real-world contexts, and by learning to explain their thinking to others. The support and engagement of other people play a crucial role in the development of higher level mathematical thinking.


Allowing students to spend too much time working on math in isolation, on paper, and on screens does not encourage students to reveal to us or to themselves where their misconceptions or misunderstandings lie. It does not allow them to benefit from hearing and seeing what mathematical fluency looks like in others. If they don’t have to speak math, few people really know the extent of their math proficiency.
