Lesson Plan

Solid Graphing: The students will review solid figures using a baggie of assorted snack mix (cones, cubes, cylinders, and spheres) and will begin a vertical bar graph showing the number of each solid figure in a bag of assorted snack mix.

Going On a Shape Hunt: Integrating Math and Literacy : Integrating mathematics and literacy allows students to develop an understanding of the place of mathematics in their world. Students are introduced to the idea of shapes through a readaloud session with an appropriate book. They then use models to learn the names of shapes, work together and individually to locate shapes in their realworld environment, practice spelling out the names of shapes they locate, and reflect in writing on the process. This lesson provides opportunities to engage students using many different learning modalities. 
Attributes of Geometric Shapes: This resource is a fun and engaging activity that will allow the students to identify and name shapes by their attributes. The students will move around and construct various geometric figures in order to build a solid understanding of the figures. 
It's All About the Shapes: The teacher begins the lesson by reading The Greedy Triangle to the class to review shape names and attributes. The students create shapes using geoboards and follow up their exploration with Shape Concentration (a game played with a partner). The teacher gathers the students together (whole group) and completes a large Venn Diagram comparing two different shapes. The students write in their journals observations they discovered during the lesson along with creating four squares in their journals (1st square  write word, 2nd squarewrite definition including attributes, 3rd square  draw a picture, 4th square  draw an example). 
The Greedy Shapes: The lesson Greedy Shapes, will explicitly teach strategies for students to identify specific attributes, such as faces and angles of triangles, quadrilaterals, pentagons and hexagons. 
Three Billy Goats Gruff Build a Bridge  An Engineering Design Challenge: This Engineering Design Challenge is intended to help students apply the concepts of force from SC.2.P.13.1 (investigate the effect of applying various pushes and pulls on different objects) as they build bridges to hold the greatest load. It is also intended to help students apply the concepts of money from MACC.2.MD.3.8 (Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately) as they strive to construct the most cost effective bridge. It is not intended as an initial introduction to these concepts. 
Lighthouses and Lenses  An Engineering Design Challenge: This Engineering Design Challenge is intended to help students apply the concepts of force from SC.2.P.13.1 (investigate the effect of applying various pushes and pulls on different objects), the concept of wind from SC.2.E.7.4 (investigate that air is all around us and that moving air is wind), and practice working with money (MACC.2.MD.3.8 solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately) as they build structures to withstand the force of highspeed winds. The first day's lesson also provides practice in recognizing and drawing shapes (MACC.2.G.1.1). It is not intended as an initial introduction to these concepts. 
Unit / Lesson Sequence

Junior Architects: In this unit, students design their own clubhouses to learn concepts such as using basic linear measurement, understanding and creating scale representations, and exploring perimeter and area measurement. In addition, they identify, compare, and analyze attributes of two and threedimensional shapes and develop geometry vocabulary.
The unit is divided into four lessons, and each lesson contains an overview, learning objectives, activity sheets for students, questions for students, assessment options, extensions for further exploration, teacher reflection questions, and correlation to NCTM standards.
Individual Lessons
 Lesson 1: Getting to Know the Shapes
 Students will be introduced to a clubhouse project, discovering the uses of geometry and measurement through the world of architecture.
 Lesson 2: Finding Perimeter and Area
 This lesson's focus is to have students consider perimeter and area while designing a clubhouse. The teacher will mark out a 10x10 "room" with masking tape to help students consider the actual size of such a small room. Students will use a handout and geoboards to find area and perimeter and problemsolve their designs.
 Lesson 3: Creating a TwoDimensional Blueprint
 Students will create a 2dimensional blueprint of their clubhouse using graphing paper.
 Lesson 4: Constructing a ThreeDimensional Model
 Students will build a 3dimensional model of their 2dimensional blueprint, solving constructionrelated problems, and decorating their clubhouse.

Virtual Manipulative

Shape Tool: This virtual manipulative allows you to create, color, enlarge, shrink, rotate, reflect, slice, and glue geometric shapes, such as: squares, triangles, rhombi, trapezoids and hexagons. 
Shape Cutter: This virtual manipulative allows students to draw geometric shapes and then decompose and recompose them into other shapes, using slides, turns, and flips to cut and move pieces around. 
Polygon Sort: This interactive Flash activity asks the user to sort shapes into a 2 by 2 chart, known as a Carroll Diagram, based on their properties. Properties used to sort include "quadrilateral" or "not quadrilateral" and "regular polygon" or "not regular polygon." 
Pattern Blocks: This virtual manipulative will allow the students to form different kinds of patterns. Learners will be able to describe parts in relation to a whole group. They will also be able to distinguish between characteristics of shapes. 
Geoboard: This extremely versatile manipulative which can be used by learners of different grades. At early grade this manipulative will help the students recognize, name, build, draw, and compare twodimensional shapes, to describe classify, and understand relationships among types of twodimensional objects using their defining properties, explore perimeter and area patterns. 
Educational Game

Shape & Solid Exploration: In this game, learners use clues to identify mystery shapes. Use everyday objects (like from the pantry) as the shapes. It is important for learners to be able to describe a shape with correct math vocabulary and to be able to visualize a shape in their head. 
Tutorial

Polygons: In this activity, you will learn how to name polygons and how to draw lines of symmetry on a variety of shapes. After you learn about polygons, you can test yourself too! 
Polygon Gallery: This combination of illustrations and narration defines convex as well as concave polygons and describes the features of various polygons. Examples of polygons shown include triangles and quadrilaterals of various types, including some that are convex and some that are concave, and even one that has a hole in it. Narration or readalong text describes the shapes for the user. Copyright 2005 Eisenhower National Clearinghouse 
Teaching Idea

Puzzling Relationships: Students will use Tangrams to explore turning, rotating, and sliding geometric shapes to fill patterns. First they will use paper cutouts before moving on to an interactive Tangram puzzle. Students will do these in pairs in order to facilitate problemsolving and reasoning, which will connect their vocabulary to actions. 
Polygons and Shapely Lines: This activity gives students practice drawing straight lines with a ruler and looking for and categorizing shapes, for example, by the number of sides in polygons. The Teachers' Notes page includes suggestions for implementation, discussion questions and ideas for extension. 
Formative Assessment

Figures With Five Sides: Students are asked to draw a fivesided figure and name the figure. 
Three Sided Figures: Students are asked to draw a triangle and justify his or her drawn shape. Then students are shown a figure that is not a triangle, but that has three sides and asked to determine if the figure on the worksheet is a triangle. 
Four Sided Figures: Students are shown a quadrilateral and asked to identify it. Then students are asked to draw another example of a quadrilateral that is different from the one that they were shown.
