General Lesson Information
 Lesson Plan ID: 33013 Title: Look Around and What Do You See Geometry Overview/Annotation: Students will learn how to identify geometric figures and their attributes in the world around them.This is a College- and Career-Ready Standards showcase lesson plan.
Associated Standards and Objectives
Content Standard(s):
 MA2015 (3) 24. Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories. [3-G1]

Local/National Standards:

Primary Learning Objective(s):

Students will be able to identify and classify geometric figures according to their attributes.

Additional Learning Objective(s):

Preparation Information
 Total Duration: 61 to 90 Minutes Materials and Resources: Teacher:Internet accessComputers for students to useMath manipulativesStudents:Should be familiar with basic geometric shapesBoy+Bot Handout Technology Resources Needed: Use interactive whiteboard tools to demonstrate the various polygons and there attributes being discussed. (Overhead projectors or document cameras may be used to discuss polygons and there attributes if interactive whiteboard is not available.) Background/Preparation: This lesson should follow a discussion on basic geometry about polygons or shapes.
Procedures/Activities:
 Before starting your lesson, let students take 3 to 5 minutes playing with math manipulatives. This will help keep their focus while lesson is being taught. Students will focus on manipulatives instead of lesson if this is not done. Review the definition of the term geometry, rectangle, triangle, circle, and other shapes you will be using in the lesson. Give students 5 to 6 minutes to list the various geometrical shapes found in the classroom. Allow students to group shapes according to their attributes. Use a class chart to list polygons or shapes found in the classroom and how they will be grouped. Discuss with students how people use polygons or shapes to build everything around them. Have student build a shape of something they would see in the world around them using their math manipulatives. Have students go to http://www.mathplayground.com/patternblocks.html to practice building more shapes they would see in the world around them.
Assessment
 Assessment Strategies Have students write an exit slip discussing geometric figures and their attributes.Have students build polygons with various materials they can find at home for homework to display in class.
 Acceleration: You can continue the lesson using build robots (see Boy+Bot for Grades K-2). Intervention: Review in a small group polygons and their attributes. Continue to use manipulatives given by teacher to complete assignments.

Each area below is a direct link to general teaching strategies/classroom accommodations for students with identified learning and/or behavior problems such as: reading or math performance below grade level; test or classroom assignments/quizzes at a failing level; failure to complete assignments independently; difficulty with short-term memory, abstract concepts, staying on task, or following directions; poor peer interaction or temper tantrums, and other learning or behavior problems.
