ST Math Chats 
Puzzle Talks (15 min) 
Remote Puzzle Talks (synchronous & asynchronous) 

Instructional Delivery 
InPerson Delivery. Student to device ratio should be 1:1 or 2:1. Project Math Chat on a screen for whole class or small group discussion. Students work individually or in pairs, then conclude with a wholegroup discussion. 
InPerson Delivery. Students do not need individual devices. Project Puzzle Talk on a screen for whole class or small group discussion. Use the playback and annotation tools to support the discussion. May use math mats, game mats, puzzle extensions, or manipulatives to support discussion. 
Asynchronous  Prework and home extensions are done remotely. Synchronous  Meet with students virtually. Use the playback and annotation tools to support the discussion. 
Student/Teacher 
Students begin by playing games individually or in pairs. They develop strategies as they solve puzzles that they can articulate during class discussions. Teachers monitor gameplay and facilitate student thinking. This provides them an opportunity to identify specific strategies, ideas, or questions to ask during class discussion. At the conclusion of gameplay, teachers engage the students in whole group conversations around 2 specific puzzles. 
Students engage in whole class or small group discussions. They share strategies, communicate ideas, critique the reasoning of classmates, and evaluate their own thinking. Teachers monitor the discussion, ask questions to prompt student thinking, explore misconceptions, and test strategies. They allow students to direct the conversation, engage students in error analysis, and build upon strategies throughout the week. *In a virtual setting, teachers use strategies to support virtual discourse. (e.g., chat, message boards, collaboration tools, virtual polls, word clouds, etc.) 

Structure 
Math Chats are 25minute minilessons that have a conclusion problem at the end. They focus on teaching and discussing specific concepts. Students begin by playing games individually or in pairs. The lesson concludes with a question to connect the concepts from the puzzle to word problems. 
Puzzle Talks are 15minute talks that can be extended throughout the week. They are more of a routine than a lesson. They focus on the concepts in the puzzle in a way that is open and encourages the teacher to go where the students go. 
Remote Puzzle Talks begin with prework that students do on their own. This prework includes two questions to think about and a sample problem to solve. Teachers meet virtually with the whole class or small groups to engage in Puzzle Talk conversation around math concepts. Teachers facilitate student discussions around math concepts, strategies, misconceptions, and vocabulary development. Extension activities can be assigned for students to complete on their own. 
Role in the Curriculum 
Can be used to introduce a concept, develop a concept, assess a concept, introduce vocabulary, bridge connections between concepts, set up for a problem or task, address misconceptions, spiral review, focus on strategies *In addition to the above, Puzzle Talks (and remote Puzzle Talks) can also be used as a number talk. 

Duration 
Math Chats are done in one sitting. It is more of a lesson structure. 
Puzzle Talks are routines to engage students in math conversations around a visual model. The concepts and discussions from Puzzle Talks can be extended throughout the week. The extensions are designed to stretch/extend the development of the concepts beyond the puzzles.  Remote Puzzle Talks provide content for students to do virtually with the teacher and remotely on their own. All activities are related to the learning from the puzzles.
