Today, we’re diving into Chapter 15 of Building Thinking Classrooms in Mathematics. This chapter is the exciting moment where we figure out how to create a fully functioning thinking classroom — not just bits and pieces, but the whole thing. It’s about total transformation.
One of the most interesting ideas in this chapter is the challenge to the assumption that simply giving students good tasks will automatically make them think. The author’s research, spanning years and involving hundreds of teachers, shows that tasks alone aren’t enough. Instead, it’s about the entire classroom ecosystem — how tasks are introduced, the environment, and the sequence of implementing all 14 practices. It’s a system, and just throwing all the practices at students at once would be overwhelming and even counterproductive.
So, how do we approach this sequencing challenge? The author provides a great visual roadmap called the Building Thinking Classrooms Framework, found in Figure 15.1. It breaks the 14 practices into four toolkits, each designed to be implemented in order, much like building a house. You wouldn’t start with the chandelier before you’ve laid the foundation, right?
Let’s explore these toolkits. Toolkit 1 is all about changing the norms and routines of your classroom. Imagine your students walking in on the first day and, instead of desks in rows, they see vertical non-permanent surfaces everywhere, ready for collaboration. This sends a strong message that this space is for active thinking. The book shares a story about a teacher who completely cleared out her classroom on the first day. Her students were shocked, but it sparked an incredible energy that set the stage for a year of thinking and collaborating in a totally new way.
But it’s not just about the physical space. Toolkit 1 also emphasizes introducing thinking tasks early and varying them frequently. The goal is to establish a culture of thinking from the start. You’re not easing students into it — you’re diving right in with engaging, thought-provoking tasks that set the tone for how the classroom will operate.
Once you’ve built this foundation, Toolkit 2 focuses on shifting student behavior. Students start to answer their own questions, move around while thinking, and take ownership of their learning. This phase empowers students while the teacher becomes more of a facilitator, guiding the learning process and trusting students’ abilities. One standout practice here is “defundring the classroom,” which might involve moving the teacher’s desk away from the front of the room. This physical shift symbolizes a change in the power dynamic, emphasizing collaboration and student-driven learning.
Next comes Toolkit 3, which is about establishing a smooth classroom flow. This involves incorporating practices like hints, extensions, meaningful notes, and consolidation. By now, students are used to collaborating, tackling challenging tasks, and taking ownership of their learning. Toolkit 3 builds on this foundation, focusing on creating an environment where students can work autonomously and productively.
Meaningful notes are a key practice here. Instead of just copying information, students actively process, synthesize, and make connections. For example, after working on a problem in groups, students create their own notes, summarizing key takeaways, drawing diagrams, or generating their own questions. This transforms collaborative insights into individual understanding.
Finally, Toolkit 4 shifts the focus to assessment. This toolkit moves away from traditional grading toward a more holistic view of student learning. Assessment becomes about more than just evaluating what students know; it’s about what they value. For instance, instead of only testing on fractions, you might assess problem-solving strategies, risk-taking, and persistence. This approach values habits of mind essential for success in any field, not just math.
Practical strategies in Toolkit 4 include having students reflect on their learning process, identify strengths and areas for growth, and set future goals. This empowers them to take ownership of their assessment and see it as a valuable learning tool. It shifts the focus from getting a good grade to becoming a better learner.
Throughout this journey, there’s an emphasis on maintaining flow. Practices like consolidation and meaningful notes help bridge the gap between collaborative and individual understanding. Consolidation, for example, involves students summarizing their group’s insights and sharing them with the class, fostering clear and concise articulation of ideas.
Implementing this framework requires a mindset shift. It’s not just about changing teaching practices but also about rethinking beliefs about teaching and learning. It’s a journey of patience, persistence, and a willingness to embrace discomfort. Building a thinking classroom isn’t a solo endeavor; it’s easier and more rewarding with a community of like-minded educators to share ideas, troubleshoot challenges, and celebrate successes.
I want to leave you with this challenge: Imagine your classroom a year from now. What will be different after implementing this framework? What will your students be capable of that they weren’t before? What new possibilities will open up for them and for you as you embark on this journey together?
