All rights reserved. commoncore.org NYS COMMON CORE MATHEMATICS CURRICULUM A Story of Units Classify Quadrilaterals Participant Debrief What makes a square different from a rectangle? Why is it important to define a square as a rectangle with four equal length sides, and not as a quadrilateral with four equal length sides? Can a trapezoid be defined as a square? Can a square be defined as a trapezoid? We classified different quadrilaterals. Try classifying these words: woman, mother, aunt, sister. Or clothes, pants, jeans. Lesson 15, Concept Development

© 2012 Common Core, Inc. All rights reserved. commoncore.org NYS COMMON CORE MATHEMATICS CURRICULUM A Story of Units Key Points Points, lines, segments, rays and angles of the first topic support the rest of the module as students construct angles and figures. A degree is not a length measure. Analyzing attributes of figures leads to more formalized definitions. Spend time physically manipulating angles and figures. It will lead to a deeper understanding.
