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.

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 […]
