Talking Math: 100 Questions That Help Promote Mathematical Discourse

Update 2022: For a recent article on how to talk about math, click here. 

Think about the questions that you ask in your math classroom. Can they be answered with a simple “yes” or “no,” or do they open a door for students to really share their knowledge in a way that highlights their true understanding and uncovers their misunderstandings? Asking better questions can open new doors for students, helping to promote mathematical thinking and encouraging classroom discourse. Such questions help students:

  • Work together to make sense of mathematics.
  • Rely more on themselves to determine whether something is mathematically correct.
  • Learn to reason mathematically.
  • Evaluate their own processes and engage in productive peer interaction.
  • Discover and seek help with problems in their comprehension.
  • Learn to conjecture, invent and solve problems.
  • Learn to connect mathematics, its ideas and its applications.
  • Focus on the mathematical skills embedded within activities.

Below are 100 questions from mathematics expert Dr. Gladis Kersaint to help you address these core areas and promote mathematical thinking and discourse in the classroom. Want these questions visible in your classroom? Curriculum Associates has released an infographic that you can print and have at your desk or in your class for quick access! Here’s a preview:

Facilitating student engagement in mathematical discourse begins with the decisions teachers make when they plan classroom instruction. In the next and final blog in this series, we will dive into the specific strategies that teachers can use to foster meaningful conversations about what students are thinking, doing and learning.

I love how you have the questions categorized by outcome goal. The infographic is one that I will be printing and using very often next year in my middle school classroom.
