## Where’s Poly? An Exploration in Geo-Dotting

What's geo-dotting?  I have no clue but that's what I'm calling this lesson. We started by asking, "What do you notice?" Our favorites: Looks like Pac-man I see dots and they make a "Y" Looks like someone went crazy with a hole punch We needed to wrangle in student...

## Colorblind Teachers, Invisible Students (Ignite – GCTM 2016)

We recently finished up our state math conference here in Georgia. Last year I shared our Ignite Talks in this space and plan to do the same with our 2016 session.  As I edit the videos and prepare to release them, there's one talk I've watched multiple times. Carla...

## The One-Handed Clock in a Digital Era

It's tough to make a case for the analog clock in our digital world. I'll leave the debate of its relevance up to the professionals. Nonetheless, the analog clock remains a staple in the majority of math curriculums. Let's take the following standard for example:...

## 3-Act Task: A kindergarten lesson captured

Over the past few months I've been asked for videos that capture a 3-Act Task being taught in the elementary grades. I didn't have any, or know of anyone that has captured an elementary 3-Act except for this Teaching Channel piece. Before moving forward, this post...

It's where my ideas go to die.  But like the mighty phoenix, I have one idea for a task that keeps rising from the ashes. It just won't die. If Bruce Willis was a math task, I've seen his face. I can't help it. I'm fascinated by them. The containers below have sat on...

## Conservation: The more things change, the more they stay the same

Every once in a while I stumble across Piaget's 7 Conservation Tasks and then I move on. This week was different because my thoughts around conservation won't go away. In a recent meeting with kindergarten and 1st grade teachers we discussed the importance of students...

## Building a Conference

I'm currently serving on the 2017 Orlando Regional Program Committee and honored to work with some great folks. When we met over the summer there was one thing we knew right from the start, we want this conference to be different. In our attempt to be different we...

## Making Sense of Invert and Multiply

As elementary teachers, we rarely have the opportunity to explore division of a fraction by a fraction.  When we do, it's normally accompanied with Keep-Change-Flip or the saying "Yours is not the reason why, just invert and multiply." Both are conceptual cripplers....
