There are many ways educators are bringing mathematical discourse into the classroom. You may have heard these lessons called number talks, math talks, puzzle talks or math chats, but they have several elements in common.
An inviting problem or puzzle that intrigues students
Asking students to justify and defend their mathematical thinking
Asking students to critique the reasoning of others
Creating math conversations in the classroom
Building number sense
These goals align with what the standards for mathematical practices ask for academic discourse: construct viable arguments and critique the reasoning of others. Many math curriculums and tools are incorporating math discourse directly into their programs to address these standards for mathematical practices.
In this blog, we’ll focus on puzzle talks. The use of ST Math puzzles to lead a whole group or small group short conversation are what we call puzzle talks. Similar to number talks or math talks, the goal is to get students to communicate and deepen their understanding of mathematics.
Puzzle talks allow educators to leverage the power of the visual models and manipulatives inherent in ST Math and use language to support the learning experience.
No matter what name you call them by, many educators see the benefits after incorporating these mini lessons into their math class structure, including:
and flexibility with numbers.
Tips for Facilitating a Puzzle Talk
Puzzle talks begin with an intriguing visual puzzle. All students may know is that the goal is to get JiJi (the penguin) across the screen.
The first task then is to determine what is going on. Ask students, "What do you notice?"
The low barrier to entry on these first questions allows all student the opportunity to engage in the conversation and build confidence.

Go to JiJi Cycle (one of the freely available games from ST Math) and share your screen with your class or a small group.
Have students talk about everything that they notice before beginning to solve it. This helps them make sense of the problem so they can persevere in problem solving.
Give students time to problem solve before asking more questions. This will encourage students not to just wait for the faster students to give the answer.
Use the guided questions to facilitate conversation as you work to solve the puzzle as a group.
Don’t be afraid to put in many incorrect answers. There are an unlimited number of tries on these puzzles, and the animation of JiJi (the penguin) will give students informative feedback that shows the results of their solution and why it was incorrect.
Celebrate success when you accomplish the puzzles!
Puzzle talks are just one way ST Math is supporting teachers in bringing math discourse into the classroom. Keep an eye out for more information coming soon about additional resources and built-in features to get students communicating and deepening their understanding of mathematics!
