Decimals Fractions General Interest Interviews One-on-One Number and Operations Numerical Reasoning

How Was Amber Reasoning?

The fifth-grade class I’m working with this year is studying addition and subtraction of fractions, and I asked to “borrow” the class to see how they would view Amber’s solution. I describe how I structured the lesson and have also included students’ writing.

Division

A Lesson Designed Around One Problem—100 ÷ 3

Did I teach an entire division lesson focused on just one problem? Yes! From giving many hundreds of interviews where students solve problems mentally, we’ve learned that solving 100 ÷ 3 is often a challenge. After recently interviewing and hearing two answers for 100 ÷ 3 that I’d never heard before, I taught this lesson.

My First Ever Card Sort . . . And I’ll Do More

Have you ever engaged students with a Card Sort? I’ve known about Card Sorts for quite a while, but this was my first go with it. The students were engaged and the experience was useful for building their understanding of division. For sure, I’ll do more.

Area and Perimeter General Interest Geometry Measurement

Part 2: Untangling Area and Perimeter

In my previous blog, I described a lesson I taught based on measuring the area and perimeter of my foot. Here I describe what happened when I returned to the class to have the students think more about the data they recorded and the mathematics it revealed.

Area and Perimeter General Interest

Untangling Area and Perimeter

This is a lesson that I’ve taught for many years when teaching about area and perimeter. I recently revised the lesson and I think my changes were an improvement. How did I change the original plan? What was my thinking behind the changes? How did the students respond?

General Interest

Milk Cartons, Origami Paper, a Desmos Tool, and More

After teaching this lesson, I taught it to another class to work out some of the kinks. My, it’s hard and time-consuming to prepare for and plan lessons. I hope my story makes the lesson accessible for other teachers and students to enjoy.

Teaching a Number Line Lesson

In my last blog, I describe how I planned a lesson about number lines. In this blog, I describe what actually occurred when I taught the lesson to a class of fourth graders. Read about which parts of my plan I followed, when and why I made some changes, and what the students did on the assignment I gave them.
