Shape Group 1 CCLM^2 Spring 2013 Leadership for the Common Core in Mathematics (CCLM^2) Project University of Wisconsin-Milwaukee, 2012–2013 This material was developed for the Leadership for the Common Core in Mathematics project through the University of Wisconsin-Milwaukee, Center for Mathematics and Science Education Research (CMSER). This material may be used by schools to support learning of teachers and staff provided appropriate attribution and acknowledgement of its source. You may not use this work for commercial purposes. This project was supported through a grant from the Wisconsin ESEA Title II Improving Teacher Quality Program.

What’s Shape Got to Do With It? Sarah Koneazny Edie Schaffner Mary Beth La Haye Lori Collenburg January 15, 2013

Learning Intention We are learning how students in Grades 1-5 develop an understanding of how attributes are used to identify, describe, and classify shapes.

Success Criteria We know we are successful when we can describe how students in Grades 1-5 develop an understanding of how attributes are used to identify, describe, and classify shapes.

Grade 1 Progression 1.G.1 & 1.G.2  Students reason about shapes  Describe & classify shapes using drawings, manipulatives & physical world objects in terms of their geometric attributes  Compose & decompose 2D & 3D plane and solid figures  Build understanding of part-whole relationships & properties of shapes

Grade 2 Progression 2.G.1  Recognize & draw shapes by given attributes (sides & angles)

Please Consider: What shape attributes will students need to know in order to sort these shapes? What questions might you ask to guide your students in this task?

Grade 3 Progression 3.G.1 Analyze, compare & classify shapes by their properties Draw shapes with specific attributes Investigate, describe & reason about decomposing & composing polygons to make other polygons Reason about congruence & symmetry Make & test conjectures

Grade 4 Progression 4.G.2 Describe, analyze, compare & classify 2D shapes by their related geometric properties of perpendicularity & parallelism Form richer concept images connected to verbal definitions associated with geometric ideas See points & lines as abstract objects

Please Consider: What other names can you give a square? How do you know? What relationship does your diagram show between quadrilaterals? What properties did you consider when you placed the shapes in the diagram?

Possible Solution

Read the Progression for Grade 5 p. 17 5.G.3 & 5.G.4 Analyze & relate categories of 2D & 3D shapes by their properties into hierarchies Relate certain categories of shapes as subclasses of other categories

Learning Intention We are learning how students in Grades 1-5 develop an understanding of how attributes are used to identify, describe, and classify shapes.

Success Criteria We know we are successful when we can describe how students in Grades 1-5 develop an understanding of how attributes are used to identify, describe, and classify shapes.
