Look for and express regularity in repeated reasoning. Notice repetitions in mathematics when solving multiple related problems. Use observations and reasoning to find shortcuts or generalizations. Second grade students generalize an efficient method for subtraction by repeatedly regrouping. Listen and look for students that exhibit the following behaviors: • notice and describe when certain calculations or steps in a procedure are repeated • generalize from examples or repeated observations • recognize and understand appropriate short cuts • evaluate the reasonableness of intermediate results

Sentence Frames: •

A shortcut that I found to solve the problem is________________. • One generalization I can make from this problem is __________________.
