The Gift of Mathematics

Earlier this month my colleagues and I had the privilege of attending the National Association for the Education of Young Children Conference in Los Angeles. Professional learning is a wonderful opportunity where one can validate ideas, gain new insights, and network with others in the field. This was my first attendance at a preschool level… Continue Reading

Attitudes Towards Play in the Classroom

There has been renewed interest among science educational researchers over the past decade in the power of “play” in the classroom. One of the researchers that I have been following is Dr. Kathy Hirsh-Pasek, a psychologist at Temple University. She is one of the founders of the Ultimate Block Party which brings together companies, makers,… Continue Reading

Coordinating Units, Part 3: Fractions

When looking at coordinating units, it is important to consider concepts other than just multiplying. One of those is fractions. Fractions would be first among these encountered by a child in school. Mental operations that must develop for a child to understand fractional ideas include partitioning, iterating, and splitting. These developments are not taught, much… Continue Reading

Subitizing, Part 2

In my last blog I mentioned that there are two distinct types of subitizing – perceptual and conceptual. I am fascinated by the subtle differences that students show and what that means about their thinking. Perceptual subitizing is the ability to recognize a number without using other mathematical processes (Clements 1999) and there are four… Continue Reading

The title of this year’s conference was “Sparking Deeper Understanding.” I headed out early the first morning of the conference with my notebook in hand, not really knowing what to expect. I have attended other conferences for different content… Continue Reading

A Dream Coming True!

The approximately 600 men and women attending this conference are almost exclusively university professors along with their graduate students,… Continue Reading
