## Math Worksheets

I often create worksheets for my students, even though every district-adopted math curriculum we’ve had has worksheets for students. I do this for two reasons: I teach differently — sometimes slightly, sometimes quite a bit — than what the curriculum writing team was thinking. There’s a particular structure/scaffold that reflects how I see the content […]

## Six Ways to See Visual Pattern #324

I know you weren’t asking, but I see n overlapping squares. — Hunter Patton (@professorpatton) November 12, 2019   What about you? How do you see the pattern in the tweet above growing? Please take a look before I completely ruin it for you. (So much for my rule of “never tell an answer.”)   […]

## Euclid’s Algorithm

I show my 6th graders this image, pointing out that this picture represents the two numbers 1 and 1 that I’d entered at the top. I then ask them to give me two new numbers — any two positive integers [that are 10 or less, for now] — and the computer will draw a new […]

## Solving an Equation with a Fraction

From CPM: The Sutton family took a trip to see the mountains in Rocky Mountain National Park.  Linda and her brother, Lee, kept asking, “Are we there yet?”  At one point, their mother answered, “No, but what I can tell you is that we have driven 100 miles and we are about 2/5 of the way there.” […]

## dudamath.com

Ethan Hall, teacher and web entrepreneur from Israel, emailed me this morning asking me to check out his visual patterns generator on dudamath.com. There’s a lot of cool graphing tools other than the VP generator. I’m kinda blown away. Go play! Go do math!

## Joint Investment

Would you have known immediately that the number 1729 is the sum of two cubes? You think you’re so smart, but you’re no Ramanujan. He told Hardy that 1729 is the sum of two cubes in two ways: 13+123 and 93+103. I read The Man Who Knew Infinity a few years ago. I might check out the movie when it hits […]

## Desmos Puppy House

We don’t cover quadratic in Math 8 this year, so we really can’t do Des-man. I come up with “Puppy House” instead so my students can still create something that allows them lots of practice with writing linear equations with domain and range restrictions. They draft the house on paper. The house needs to have a minimum of 6 […]

## Grade 6 Rocks Visual Patterns

I’m always happy to hear how teachers use visualpatterns.org with their students. Michael Fenton shares how he uses the patterns with Desmos. And this.

## Reversing the Question

Don Steward posted this on Sunday. Like Don, I really like this task and also think it has a certain Malcolm Swan je ne sais quoi about it. I showed only the top part to my 6th graders, and I gave them 2 minutes to write down what they notice. In addition to noticing the given information, the students also mentioned: […]
