In this lesson from Illuminations, students develop number sense through a change in approach to the teaching and learning of mathematics. This approach focuses on students and their solution strategies rather than on a “right answer,” on thinking rather than on the mechanical application of rules, and on student-generated solutions rather than on teacher-supplied answers.
