Unit Coordination

Put Me in, Coach

Every once in a while, something will happen at work that makes me miss the classroom and the kids that I taught. It’s like a craving at times, but today I feel more like the athlete on the bench that wants a shot at winning the game. Here I am on the sidelines, wanting to… Continue Reading

Takeaways from Subtraction part 2: To Take Away or Not to Take Away

In my last blog entry, I described three goals suggested by Dr. Les Steffe which support introducing subtraction as take away. Yet, there is a belief among some math teachers that thinking of subtraction as take away interferes with future mathematical development. They argue that using the words “take away” should be eliminated completely from… Continue Reading

Coming in Spring

As the Fall semester comes to a close, we are preparing for Spring at our school sites. Next on the list for our team is fractions. I am so excited to begin working with students to understand how they think about fractions and what we as teachers can do to give them opportunities to increase… Continue Reading

Takeaways from Subtraction (Part 1)

Why is subtraction hard? This question can be heard from many young children, but often even from adults. Whenever adults do mental math, they tend to have an easier time with addition, multiplication, and simple division than with subtraction. For the past three months we have been engaging young children in subtraction situations while considering… Continue Reading

Laying the Foundation for Fractions

This spring, the Coordinating Units team will begin looking into how students develop an understanding of fractions. We have been reading the research in this area done by Dr. Leslie Steffe. In his research with students he theorizes that if students have a fully developed whole number sequence and are able to use it flexibly,… Continue Reading

Games That Promote Mathematical Thinking

A few years ago, I went to a conference where I was able to listen to Keith Devlin, a noted mathematician from Stanford, talk about using technology, particularly computer games, to help students think mathematically. He made the case that the symbols we use to represent mathematics, like numerals, operation signs, etc. create a barrier… Continue Reading
