A rubric to assess the eight Common Core State Standards of Mathematical Practice
Update 8/2/21. After reviewing feedback from teachers who have implemented the rubric in its draft form, I feel confident in removing that modifier of “draft.” Consider the rubric below for the Standards of Mathematical Practice as Version 1.0. The Common Core Standards of Mathematical Practice (MPs) have been available for a while now. They lay…

Whenever and however we come back together as math classes this Fall, we’re going to need to spend considerable time building up students’ mathematical identities. Chances are students are going to be entering your classroom with a wider array of math learning experiences over the prior six months than ever before. Therefore we need a…

As useful and helpful as these are, the most reliable-to-hit-the-content, easiest-to-plan problems come from stuff that already exists. Textbooks and online problem sets are the most robust source of quality…

The following Problem Based math lesson covers the concept of transversals crossing parallel lines and their angle relationships. The scenario of the task predicated on needing to determine “safe” and “troublesome” intersections in town. Intersections that are closer to right angles are deemed “safe,” while intersections with extreme angles result in limited-vision turns. But that…
