## The Right Question Institute

From www.aish.com: Isidore Rabi, winner of a Nobel Prize for physics, was once asked why he became a scientist. He replied: “My mother made me a scientist without ever knowing it. Every other child would come back from school and be asked, ‘What did you learn today?’ But my mother used to say, ‘Izzy, did […]

## Deconstructing a Lesson Activity – Part 2

Previously: Deconstructing a Lesson Activity – Part 1 No matter what I write in this Part 2, I hope it’s not a wrap-up of this topic. On the contrary, I hope it opens up and extends our conversations on improving the implementation of rich tasks in our classrooms. Physical arrangements, whiteboards, groupings. The student desks are […]

## Deconstructing a Lesson Activity – Part 1

[I’ve decided to break this post into two parts because I don’t want to bore and/or discourage you, and I need to take a breather. These two posts in particular are truly my labor of love because if there’s one thing that I find myself proficient at implementing in the classroom it is problem solving. […]

## Venturing Into the Sequel of Penny Pyramid

I didn’t get around to doing Penny Pyramid when I first saw it last year. But Dan‘s 3-post series and Nathan‘s recent mention of it were the reminders I needed to make it happen. Act 1 how many pennies how much money is that how long did it take who in their right mind would do this/who has that patience how much […]

## Stack ’em High

My algebra kiddos are doing Dan Meyer’s Stacking Cups because Andrew Stadel did the lesson and wrote glowingly about it. But Andrew used only one-size cups, I used three (that’s three!) different sizes. Who’s better now. Just eyeballing I ask students to look at me, look at this 12-oz Styrofoam cup that I’m holding, and estimate how many cups they […]

## Equilateral Triangles

Thank you to Dan Meyer for this great task idea on equilateral triangles. Act One is this video which asks for a ranking of how well each teacher had drawn his equilateral triangle. But as soon as I saw the video, two thoughts came up: We’re in a 0:1 classroom right now, and having the whole class come […]

## Mr. Meyer’s Taco Cart

Won’t be long before I have to change the post title to Dr. Meyer’s Taco Cart. This lesson went really well today. Act 1: We watched the video clip. Their guesses: Me: That was fun. Kinda split in the middle there with your guesses. But that question of who gets there first only gave you two choices, […]

## Mr. Stadel’s File Cabinet 3-Act Lesson

Monday evening I got a tweet from @mr_stadel: Then he shared his uploaded File Cabinet – Act 1. I tweeted back, “Oh, I’ll start with this tomorrow then!! Thanks!!” Andrew had no idea I could really use a good lesson the next day to kick off our chapter on Areas and Volumes of Solids — specifically, Prisms. Act 1: We […]
