abstract = {From the text: In Chapter 10, the authors describe how ``early algebra is not the same as algebra early" with respect to: the role of background contexts and quantities, how notation is introduced, and its connectedness to existing topics in the early mathematics curriculum. They argue that algebra requires a shift in focus from the individual case to sets of cases -- a kind of generalization for which the concept of function will play a key role. They find that young students can make remarkable progress in this shift when topics of early grades mathematics are reframed in this way.},
