MP1: Make sense of problems and persevere in solving them.

Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. They monitor and evaluate their progress and change course if necessary. Older students might, depending on the context of the problem, transform algebraic expressions or change the viewing window on their graphing calculator to get the information they need. Mathematically proficient students can explain correspondences between equations, verbal descriptions, tables, and graphs or draw diagrams of important features and relationships, graph data, and search for regularity or trends. Younger students might rely on using concrete objects or pictures to help conceptualize and solve a problem. Mathematically proficient students check their answers to problems using a different method, and they continually ask themselves, \"Does this make sense?\" They can understand the approaches of others to solving complex problems and identify correspondences between different approaches.

Discussion and Supporting Materials

Thought starters

1. How does the graphic organizer help scaffold problem solving for students?

2. Why does Ms. Saul choose to have students work alone without help?

3. How do "Heads Together Butts Up" and "Student-led Solutions" contribute to the class culture around problem solving?

Students work independently using a graphic organizer to solve a problem at least three ways and then present their solutions to their group and class. Ms. Saul emphasizes that mistakes are okay and encourages students to wrestle with problems independently to build their confidence in problem solving on their own.

Third grade teacher Jen Saul uses a variety of silent signals to encourage participation and engagement in math. Jen has signals to show agreement, thinking, answers, and appreciation. After thinking about the needs of her students, Jen developed silent cheers as a way to show excitement and to relieve disappointment over not being called on.
