We all acknowledge that data analysis and representation is a key part of our math curricula in the 21st century. But while it’s baked into Common Core and other state standards, it can be a bit unwieldy at lower grades. One of the barriers between students and sophisticated data analysis has been (until recently) lack … Continue reading Delightful Data Visualization: Polypad and Young Statisticians

## HB 1557 and lines in the sand: Understanding and communicating the purpose of Florida’s “Don’t Say Gay” bill￼￼

(This website is about math and math education. While I don't normally write about Topics of the Day, it's crucial that parents and educators understand the text and purpose of Florida's House Bill 1557, which specifically targets teachers and students.) I’ve never been much of a proponent of fleeing a state because you disagree with … Continue reading HB 1557 and lines in the sand: Understanding and communicating the purpose of Florida’s “Don’t Say Gay” bill￼￼

## What’s the “of” in a percentage grade? A percentage of what, exactly?￼

In my Numbers, Operations, and Patterns course that I’m teaching, we discuss rational numbers a lot. We’re working through Teaching Fractions and Ratios for Understanding by Susan Lamon. It’s an indispensable book for the deep dive into rational numbers as well as the inherent glimpse into the development of elementary-to-junior-high mathematical thinking. Anyway, we often … Continue reading What’s the “of” in a percentage grade? A percentage of what, exactly?￼

## Musings on Mathematical Creativity

This semester I had to write a literature review of a topic of our choice. Last year I focused on assessment, which will be my dissertation topic. I wanted to try something a little more “lighthearted” this year, so I went with Mathematical Creativity. I’m not going to reproduce my paper here, but I did … Continue reading Musings on Mathematical Creativity

## Part 6: Scoring with Humility

This is the sixth and final installment of a mini-series on rubric design and use. Be sure to check out the other posts as well as the initial post. Your grades are qualitative data, not quantitative data. Whether you’re using a rubric on a complex task, or assigning a number out of 100 from a … Continue reading Part 6: Scoring with Humility

This is Part 4 of a mini-series on a rubric masterclass. Be sure to check out the Intro post and subsequent posts. Before we get to it today, I want to offer a bit of a warning: this piece of rubric-land gets very sticky, very fast. It represents the tension between our aspirations as growth-minded educators and … Continue reading Part 4: Scores, scoring, grades, and grading

## Part 3: Defining Proficiency & Moving Outward

This is Part 3 of a mini-series on a rubric masterclass. Be sure to check out the Intro post and subsequent posts. Once we’ve identified our specific and common outcomes, we need to identify specific markers that will indicate where students are on the spectrum of proficiency. In fact, that’s where we get our next little bit … Continue reading Part 3: Defining Proficiency & Moving Outward

## A Rubric Masterclass Part 1: Selecting Rubric Worthy Tasks

This is Part 1 of a mini-series on rubrics. Be sure to check out the Intro post and subsequent posts. It took me a while to figure out the whole rubric game. I'll admit, I was relatively anti-rubric in the middle of my career. Maybe that's because I wasn't shown how to construct one. Maybe … Continue reading A Rubric Masterclass Part 1: Selecting Rubric Worthy Tasks

## A Rubric Masterclass

This blog post introduces a new mini-series from Emergent Math: A Rubric Masterclass. Be sure to check out Geoff's previous mini-series: Routines, Lessons, Problems, and Projects and Your Math Syllabus Boot Camp. The past two summers I’ve created Emergent Math “miniseries”. They’re an opportunity to do a deep dive into crucial aspects of the math … Continue reading A Rubric Masterclass
