Attend to precision. Communicate precisely to others by crafting careful explanations that communicate mathematical reasoning by referring specifically to each important mathematical element, describing the relationships among them, and connecting their words clearly to their representations. Calculate accurately and efficiently, and use clear and concise notation to record their work. Third grade students attend to precision by creating shapes that can be classified based on specific attributes. Listen and look for students that exhibit the following behaviors: • compute accurately • use symbols appropriately • accurately use problem-solving strategies • specify and use units of measure appropriately • decide whether an exact answer or estimate is needed • calculate efficiently, accurately, and fluently.

Sentence Frames: •

The exact answer is needed because ________. • My answer is clear because ________. • The correct definition is _____.
