Our work with four second graders having difficulties in math.
Luz Maldonado and I worked with four second graders who were having difficulties in math, for about 10 weeks. Each of us got together with them once a week, on separate days. What follows are my reflections on working with these four children. As you will see, our work soon turned to diagnosing and developing base-10 knowledge, a key construct in elementary math.
