I swear by the NCTM addenda series book entitled Developing Number Sense,
grades 5-8. I use a lot of this material with the students I have in a
university course for Math Content for Elem Students.

Also, I believe in lots of estimation. For instance, when I tutor middle
level school students I will give them four different cutouts of simple
shapes and ask them to order the cutouts in order from smallest area to
largest. Then, using a ruler, find the areas of the four figures. Finally
we compare their estimate with the figures and discuss why it might have
varied from the reality. Also, when they finish with the estimation part, I
might ask them to explain why they ordered them that way. The more students
estimate and explain, the more their number sense improves.

I hope this helps. Linda
