by Math Solutions Professional Learning Team, January 10th, 2017

After I told Steven, the man seated next to me on an airplane, that I was a math teacher, he described the Dealing in Horses problem that he was given at a corporate management training session. The problem has been one of my teaching staples ever since.

Why I Like Using Open Number Lines (Though I Don’t Like the Name)

by Math Solutions Professional Learning Team, December 13th, 2016

This post is about subtraction, which is typically difficult for students to learn and for teachers to teach. Think about 503 – 398, for example. To estimate the answer, I can change the problem to 500 – 400 (rounding 503 to 500 and 398 to 400). That gives me an estimate of 100, which I know is close. But how can I know if the actual answer to 503 – 398 is greater or less than 100? I raised this question with third graders.

Post from Marilyn’s Blog: The 1–10 Card Investigation

by Math Solutions Professional Learning Team, June 03rd, 2016

The 1-10 Card Investigation has a big payoff with students. It engages their interest, involves them with making sense of a problem and persevering to solve it, and gives them experience with evaluating their progress and changing course as necessary. Plus it has a playful aspect that too often is lost in math class.

Post from Marilyn’s Blog: A Problem with a Word Problem

by Math Solutions Professional Learning Team, May 13th, 2016

A word problem on a third-grade standardized math test didn’t call for a numerical answer, but instead asked students to decide if the problem should be solved by adding, subtracting, multiplying, or dividing. One third grader complained to his teacher, frustrated because he thought there was more than one correct possibility.
