Sparks in the Desert – A Beginning Conversation on Counting On – Part 2

Are there any dangers in training your students in the “strategy” of counting-on? After reading Dr. Les Steffe’s work, I would argue it is harmful. He calls counting-on a non-teachable scheme.  This means that if you want counting-on to be meaningful for students you can present situations that would promote their construction of counting-on, but… Continue Reading

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
