This resource provides a collection of question stems designed to foster deeper mathematical thinking and discourse among K-5 students during daily lessons. The prompts are categorized into four key areas: Problem Solving, Reasoning & Proof, Making Connections, and Reflection. Each category contains specific questions that guide students to engage with mathematical concepts critically. For example, under Problem Solving, students are encouraged to articulate what the problem is asking and to elaborate on their thought process. The emphasis is on encouraging dialogue and helping students make connections with their learning, while also inviting reflection on their own thought processes and strategies. Teachers can utilize these prompts effectively by displaying them in the classroom to facilitate ongoing mathematical discussions.
