Getting Organized for Success with Math Manipulatives: Desks (Part 1 of 5)

Date: April 5th, 2016

When I teach math with manipulatives I have to be extremely organized, or I’m inviting a perfect storm. How I set up my classroom and manage materials are absolutely central to a lesson’s success.

Date: February 25th, 2016

In the first part of my discussion about keeping control of my class while teaching with math manipulatives, I covered how I teach students to take their hands off the blocks within two seconds and give their full attention to me.

How do I keep control of my classroom when I’m teaching with manipulatives? (Part 1)

Date: February 9th, 2016

Before I put a single manipulative in front of a single student, I invest a little time in telling them about my expectations of their behavior.

#8 When your students subtract, can they explain how they got their answer?

Date: December 30th, 2015

Tom Schersten’s Game Mat Tom Schersten: In this video, I’m going to model subtraction on the My Way Highway. Usually when we teach subtraction, we are using the removal model, where what we’re taking away is already embedded with what we’re starting with. Today we’re going to be using the comparison model so you get […]

#5 When your students add, can they explain how they got their answer?

Date: May 19th, 2015

Tom Schersten: It’s not until fourth grade that the common core standards expect kids to have memorized the traditional algorithms for addition and subtraction. That means that in the second and third grades, we have to have other ways of the kids modeling how their thinking is going.

Date: May 6th, 2015

Tom Schersten: This video is going to show the power of understanding place value when adding three- and four-digit numbers. Please take a look at the example that I have here: 375 add 256. I’m going to start adding on the left side, because I know that that stands for 300, and this is 200, […]
