Too bad this isn't in print anymore. If we want to free people from paper and pencil, and prepare them properly for algebra skills, then we would use techniques found in this book. I'm speaking as a 40+ year instructor of math, from pre-K through precalculus. I use graphing calculators heavily in upper level math classes, but number sense and fluency is the important part for everything preceding algebra.

Wonderful resource to teach mental math skills! I’ve used it in the classroom, and the students enjoyed the exercises.
