# Estimation Wall 2.0

After three years, the mighty Estimation Wall returns.

### The Task

I use Estimation 180 in my Pre-Calculus and Calculus classes. The kids love (and hate) these things. For every class that screamed "one more, one more, ONE MORE!!!" there was the boy who would see the task and lament "and now to guess and have my dreams crushed."

The kids are pretty familiar with the set up, so it wasn't hard to get them excited about making their own. Each student had to make 2 tasks using four pieces of paper, two for the questions and two for the answers. Pictures had to accompany each question and answer. The answer pictures needed to be presented in a way that no one would argue with the correct answer, or wouldn't be obscure to the point where the viewer would say "well, if you say so."

### The Players

I was going to use one 90 minute block period to crank out the tasks. Prior to the work day, kids were asked to fill out a Google Form telling me their tasks. They also needed to make a plan to take their pictures in advance or bring whatever they needed to school and take the pictures there. They had access to the Chromebooks and my printer.

### The Mess

On work day, we briefly went over expectations, and the room exploded into activity. I wish I had a time lapse to show you the random things going on. All sorts of tasks were being staged around the room, and kids were helping each other modify ideas when something didn't quite work out.

At the conclusion, I had collected a small mountain of tasks all ready to for display.

In total there were 114 tasks. I have two classes of Pre-Cal and each class took a bank of lockers for their display area. The work day was right before winter break. On the first day of the second semester, we took about 60 minutes of another 90 minute block day to assemble the walls.

See a question, make a guess, open the locker to check. Simple as can be. So much fun from start to finish. Calculus kids were a little upset they missed out on this one.

My favorite part of the whole thing? I just wandered around enjoying the sites. The kids didn't need much from me other than supplies and the occasional printer troubleshoot. We had spent an entire semester establishing a technology workflow that the kids knew well and worked well for us.
