<p>Prekindergarten: Unit PK.G.A.1-2, Identify and describe two-dimensional shapes (circles, trian gles, rectangles; including a square, which is a special rectangle).</p><p>Lesson Seed: My Shape Book (Lesson seeds are ideas for the domain/cluster/standard that can be used to build a lesson. Lesson seeds are not meant to be all-inclusive, nor are they substitutes for instruction.)</p><p>Domain: Geometry Cluster: Identify and describe two-dimensional shapes (circles, triangles, rectangles; including a square which is a special rectangle. Standard(s): PK.G.A.1: Match like (congruent and similar) shapes PK.G.A.2: Group the shapes by attributes</p><p>Purpose/Big Idea: Students will identify and describe two-dimensional shapes and match similar shapes when given various two-dimensional shapes. Students will also be able to explain the groupings made when sorting. Students will identify shapes found in their environment.</p><p>Materials:  Shapes, Shapes, Shapes by Tana Hoban (or other shape book with photographs of real objects)  Magazine pages  Resource Sheets1A-E: My Shape Book Pages  Glue  Scissors</p><p>Activity:  Read Shapes, Shapes, Shapes, noting all the real life objects that re various shapes.  After reading, show children one of the pages from a magazine and the My Shape Book pages.  Ask volunteers to find a shape on the page.  Cut the shape out and ask a volunteer to glue it on the page that has a shape that is the same.  Repeat.  Over the course of a few days, allow students to add shapes to their own booklets.  Allow students to share why they sorted the shapes the way they did.</p><p>Guiding Questions:  What real world shapes did you find?  Why did you sort the pictures the way that you did? Prekindergarten: Unit PK.G.A.1-2, Identify and describe two-dimensional shapes (circles, trian gles, rectangles; including a square, which is a special rectangle).</p><p> How are these shapes alike? How are they different?  If I turn this picture like this, does it change the shape?
