The Common Core Standards of Mathematical Practice (MPs) have been available for a while now. They lay out eight habits that mathematicians embody. They've been instructive in what to teach and how to teach. They've also been helpful in providing a comprehensive vision of what math classrooms can be. MP1. Make sense of problems and … Continue reading A DRAFT rubric to assess the Common Core State Standards of Mathematical Practice

## Where does a letter occur in a word? A matching activity

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 … Continue reading Where does a letter occur in a word? A matching activity

## Active caring: now more than ever

I don't know jack shit about teaching remotely. There are many, many blog posts and articles that'll inform you of best practices, useful websites, fun apps, sample schedules and the like. The most helpful of which I find to be open and honest reflections on what it's like to teach entirely remotely, unexpectedly, and without … Continue reading Active caring: now more than ever

## How a problem becomes a lesson

Sometimes we overthink it. We (*ahem*) create big curriculum maps full of dynamic problem based lessons created by the most intrepid teachers on the internets. 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 … Continue reading How a problem becomes a lesson

## Transversals Lesson: Street Views

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 … Continue reading Transversals Lesson: Street Views

## Geometric Constructions Task: Pizza Delivery Regions

The following task is probably best suited for the a beginning unit on Geometric Constructions or use of a compass and straight edge. However, you may also wish to use it as a fun review as students reenter your classrooms in January, groggy from two weeks of sleeping late. The task is adapted from the … Continue reading Geometric Constructions Task: Pizza Delivery Regions

## Why don’t students feel like they’re learning? (when they actually are)

It's something we've all experienced: we'll lecture and feel like students got it. Maybe they'll even do well on the practice problems we assign them. Then the next day or the next week we try something a bit more open ended - a problem based lesson, a 3-Act Task, an Open Middle task - and … Continue reading Why don’t students feel like they’re learning? (when they actually are)

## Five steps to plan a problem based lesson

Far from a simple undertaking, incorporating more inquiry in your class is a challenging process. You and your students may have to unlearn some of the tendencies you’ve built up over the years. So I hope you don’t take this “five steps” post as a flippant, “it’s so easy” post. The opposite is true: problem … Continue reading Five steps to plan a problem based lesson

## Math Mindset and Attitudes Survey

The start of the school year offers a unique time in the academic calendar to obtain some baseline data on how your students view themselves as mathematicians and the discipline of math itself. Most beginning-of-year info sheets solicit information about students' passions and/or guardians' phone numbers. This year, I encourage you to ask some questions … Continue reading Math Mindset and Attitudes Survey

## Specifics before Strategies

In this blog post, we'll explore how to get specific with math or non-math classroom issues before we develop strategies. We'll also see an example of how to build a rubric from the ground up. === “My kids just won’t work together.” This (or something like it) is a common complaint I hear during professional … Continue reading Specifics before Strategies
