Does Changing Subtraction to Addition Make It Easier?

Teachers have always told me that paper-and-pencil subtraction when problems call for regrouping is hard to teach and hard for students to learn. Much harder than addition. So why subtract when you can always add? That’s what my friend Nicholas thought, and he taught me how.

A Reponse to Joe Schwartz’s Blog about Algorithms

I was recently planning to teach my friend Ruth Cossey’s elementary math methods class at Mills College in Oakland, California. Digging through my collection of student work, I found a paper from a third grader I had interviewed. When doing interviews, I typically ask students to figure out answers in their heads, but I agreed when Nomar asked for paper and pencil for some of the problems.

Fractions on a Number Line

The fourth graders I’m working with on a regular basis are learning about fractions. During a class conversation, one student declared, “Fractions aren’t numbers.” Most of the others in the class agreed. I tried to help with the misunderstanding by teaching a lesson about placing fractions on a number line.

The Game of Pathways

I like the multiplication game of Pathways. It engages students’ interest, helps develop their familiarity with the times table, and encourages them to think strategically. It's been a part of my teaching for a long time. Recently I came up with a way to introduce the game that made it easier for students to learn to play. It was a huge success. Read about what I did and how the students reacted.

Fix It: An Activity for Ordering Fractions

At a math workshop, the presenter suggested that students have opportunities to be producers as well as consumers of their learning in the classroom. I put this advice into action with fifth graders, using the activity of Fix It to provide students additional experience with comparing and ordering fractions.

One Children’s Book . . . Different Grade Levels

In a previous blog, I described a lesson I taught to second graders using the wonderful children’s book One Is a Snail, Ten Is a Crab. At John Muir Elementary School in San Francisco, I observed two other lessons using the same book, one in Kindergarten and the other in fourth grade. The lessons were a joy to observe, and I feel that my own teaching repertoire has now been enhanced.

The Equal Sign: What It Really Means

Students begin learning about the equal sign in the early grades, and Quack and Count by Keith Baker is a terrific children’s book for helping with this in kindergarten and grade 1. It’s one of my favorite children’s books for teaching math. (Yes, yes, I know I have lots of favorites.) Here I describe the lesson I taught and what occurred.

Can You KenKen?

I’ve taught students in grade 2 through middle school how to solve KenKen puzzles. If you’ve never solved KenKen puzzles yourself, or haven't engaged your students with them, read about how I’ve introduced them in the classroom. But be warned: KenKen puzzles can be addictive.

Postscript about the Number Eleven

A comment posted on my previous blog was a Yikes! experience for me. The comment was about one of the ways to make 11 that I included in the book I created for my grandson’s birthday. The comment was a wonderful reminder about how arithmetic, algebra, and geometry connect.
