"If you have even one student in your class that struggles with math, then take a Pam Harris workshop."

-Christopher Peterson, West High School, CA




Have you ever felt frustrated that you have to teach content you were never taught to unprepared students? Do you wonder how it is that you work so hard and your students aren’t doing better?

If you’re a middle school mathematics teacher, leader, or professional learning facilitator looking to energize your teaching, then you probably already know that your students come to you unprepared, have gaps, sometimes not even knowing their multiplication facts.

This course will help you feel empowered, enlightened, and energized

By using the Development of Mathematical Reasoning to guide your decisions, you choose tasks that are open enough so that all your students can access and each are challenged.

As a Participant

You will identify how the teaching of proportional reasoning has changed and why it matters so that you can base decisions on helping your students develop.

You will learn how to begin, by providing support for students who don't know their multiplication facts so that you can help students develop multiplicative reasoning and proportional reasoning at the same time.

You will extend the learning to more complicated contexts so that you can strengthen students' reasoning.

You will engage in problem solving so that you can parse out the thinking needed to solve proportional reasoning problems.

You will learn actionable strategies while engaging in the instructional routine called Problem Strings so that you can develop students' proportional reasoning and build specific mathematical strategies.

You will study three lesson types so that you can to learn to introduce, construct, and solidify proportional reasoning.

You will analyze expert teacher moves so that you can energize your classroom and keep students engaged in sense making.

You will get clear about the nuances of ratio, rational number, fraction, and rate so that you can help students use them appropriately.

Online Participants Think It's Great Too!

Your questioning techniques and encouragement put these students so at ease that they were willing to take risks and explain their thinking. We teachers in our classroom rarely have a chance to tweak our teaching by observing others; this unique workshop has been a golden opportunity to soak in techniques from a master teacher. So much better in many ways than a book or a short session at a math conference.

I have always wanted to help students understand the "why" of the math they are learning. I've struggled being able to do that consistently, and well, through all of the content. I also definitely thought knowing the algorithm was more important than I do now. Looking back, it's hard to see how those two mindsets fit together.  

I had a lot of a-ha moments throughout this workshop. It's hard to pick one, but I'm going to say ratio tables. I never realized how versatile they can be. I almost always go straight to a ratio table now when approaching problems. It just makes so much sense!  

Teaching students to think and reason through a problem, while still covering the standards, is so doable! We often ask students if their solution is reasonable, and tell them how to "know" if it is reasonable, yet teaching how to determine reasonableness was neglected. That will soon be a thing of the past in my classrooms.

Sharing the idea of how to reason proportionally is huge for me. I have made connections to percentages that I never saw before. It has opened my eyes to conceptual understanding that I didn’t have before.

I loved that Pam responded directly to my posts. It felt more personal and that she was connecting with me and cared about my questions and thoughts.

I had so many times during this workshop in which I thought "I wish I were still teaching" and "I wish all of our teachers in our district could go through these courses". I used ratio tables in my classroom when I taught to help with proportional thinking, but unfortunately when I first started using them I used it as another algorithm in a way that I showed the students "how" to do it rather than letting the construct them in their own way. The more I learned about them the more I let students do the thinking, but I always get excited when working through problems like we did in this course as I look for different ways to see the problem and reason through the math.  

It was really great to see the student videos. Our teachers always ask what does this look like with students or "my" students can't do that. It was evident that the students in the video were at different levels and you engaged all of them. I loved the equity map. We do a lot of equity work in our district and this will definitely be something I share with teachers.

Pam Harris’ workshop Building Powerful Proportional Reasoning is a GIFT. The video clips are engaging, and I felt like I was right there in the room with Pam, as she expertly posed questions and pushed the thinking of everyone forward. I found myself laughing at times, challenged at times, and thinking about my own learning after walking away from my computer screen. 

The problems and examples provided are, indeed, powerful examples of how to develop proportional reasoning. Live sessions are combined with videos showing routines and instructional moves with students. These are followed by a focused discussion around how and why those decisions are made. Participants walk away with a very clear example of teaching that they can then used to shift their own practice. 

I will be recommending this workshop for all teachers working with this content, as well as for anyone interested in improving their own proportional reasoning. This workshop truly was a joyful mathematical experience for me!

This course was a perfectly curated introduction to the world of proportional reasoning. Pam Harris guides you through your own thinking, seamlessly connecting pedagogy and content to build your confidence in teaching ratios. The online platform allows you to engage with the instructor and participants while fitting the course into your own schedule. Highly recommend!  

One of the most helpful things was seeing how the context could anchor and connect multiple learning structures (problem string, word problem), models, or strategies. I realized I could use middle school problem strings that build proportional reasoning to help upper elementary school teachers realize the importance of building multiplicative reasoning (and move away from the standard algorithm).

Pam Harris’ Grassroots Workshop, Building Powerful Proportional Reasoning, is one of THE best proportional thinking courses I have ever seen — and that is a LOT coming from a University Professor talking about a non-University course! I couldn’t believe all that one could get in this course for the price – I would pay triple the retail price for all the learning that is involved!

Pam is a powerful and dynamic presenter, one who has cleverly weaved her multi-sensory approach into an online course. You will watch videos of real-live classes, read articles, learn new ways to think mathematically, and much, much more! She has also included a section that helps you, the educator, learn how to apply what you’ve learned directly to your classroom. She provides you with what to try out in your classroom and what to look for. She’s made the learning so easy for her participants that a concept that often challenges us seems easy! The Message Boards provide an integral platform for educators to network and learn together. If you love #MathStratChat, then this is right up your alley!

Overall, I am blown away by the sheer capacity of this course, from its deep connections from the top and best research in the field on proportional thinking to the learning trajectory built over the modules, you will absolutely be astounded by the amount of growth as an educator and learner you will have. Pam is right. Math IS Figureoutable.

I’m Pam Harris and I empower teachers to be the teacher they want to be.


I have been working with educators for over 20 years as a classroom teacher, university instructor, and teacher trainer, as well as writing books and creating resources for teachers.

As a beginning teacher, I worked hard to make lessons understandable and interesting, but I didn’t realize how much I relied on rote memorization and repeating procedures until I immersed myself in math research. This fundamentally changed the way I do and teach mathematics so that teachers and students reason mathematically, not mimic like robots.
