This year, I am trying out Estimation 180 in my Math Concepts class, a class for 9th graders not yet ready for Algebra 1. After two weeks of giving students the formula for percent error EVERY SINGLE DAY, I finally made an Estimation 180 Poster!

This poster was inspired by a tweet from Lisa Bejarano.

Here’s my version of the Estimation 180 Poster. I printed the poster on 11 x 17 cardstock.
