Polygon Data Collecting Scavenger Hunt
(Download as Microsoft Word Documents: Instructional
Plan, Chart)
Names of Group Members: Kristie Rosgone, Elizabeth Dufner, Christie McAllister, Audrey Griffin, Cynthia Smith-Kern
Topic/Theme: Geometry, Polygons, Data Collection, Graphs
Level: Fourth Grade
Time Element: Three 40 minute periods
NCTM Standards Addressed:
Geometry Standards
Analyze characteristics and properties of two- and three-dimensional
geometric shapes and develop mathematical arguments about geometric
relationships
· identify, compare, and analyze attributes of two- and three-dimensional shapes and develop vocabulary to describe the attributes;
· classify two- and three-dimensional shapes according to their properties and develop definitions of classes of shapes such as triangles and pyramids
Use visualization, spatial reasoning, and geometric modeling to solve
problems
· recognize geometric ideas and relationships and apply them to other disciplines and to problems that arise in the classroom or in everyday life.
Data Analysis and Probability
Formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them
· collect data using observations, surveys, and experiments
· represent data using tables and graphs such as line plots, bar graphs, and line graphs;
Select and use appropriate statistical methods to analyze data
· compare different representations of the same data and evaluate how well each representation shows important aspects of the data.
Develop and evaluate inferences and predictions that are based on data
· propose and justify conclusions and predictions that are based on data and design studies to further investigate the conclusions or predictions.
PA Math Standards Addressed:
Geometry
2.9.3D Find and describe geometric figures in real life

PA Math Anchors
Addressed:
M4.C Geometry
M4.C.1.1.1 Identify, classify and/or compare two-dimensional figures.
M4.E Data Analysis and Probability
M4.E.1.2.1 Graph data or complete a graph given the data.
Objectives: *Students will be able to name and identify the properties
of two-dimensional figures.
*Students will be able to recognize and identify two-
dimensional figures in their environment.
*Students will be able to collect and organize data using a
frequency table.
*Students will be able to display their data using an appropriate graph of their choice.
Procedure:
DAY ONE:
1.) Students will be familiar with various polygon shapes including: triangle, square, rectangle, rhombus, trapezoid, pentagon, hexagon, and octagon.
2.) After a brief review (“Who can tell me a characteristic of a triangle?”), distribute the Polygon Characteristic worksheet.
3.) Using the worksheet, students will list the previously taught properties of each of the polygons. (Remedial students will be given a Polygon Characteristics Word Bank to use.)
4.) Teacher and students will review and discuss the worksheet. (ex: Think, Pair, Share activity)
5.) Distribute the Frequency Chart and Table and explain the procedures for the project using the overhead projector. After the project has been explained and discussed in detail, students will make predictions in their math journal. (Which shape do you think you will find the most in your home? Which shape do you think you will find the least in your home? Explain.
DAY TWO:
1.) The different types of graphs will be reviewed. For example: If a child suggests a pictograph, ask them to illustrate and explain it on the board.
2.) After a detailed discussion of graphs, pass out graph paper and rulers.
3.) Students will choose a type of graph to report their data. (Graphs will be made using the criteria previously learned.)
4.) When graphs are complete, students will orally share them and then hand them in to be displayed.
DAY THREE:
1.) Scavenger Hunt Object Discussion-
Ex: What are some of your examples of a triangle/square/rectangle?
2.) Facilitate discussion with prompts-
Ex: Are you sure? How do you know?
3.) Wrap-up
-Review properties of each shape
-Bonus questions (spheres, prisms)
-What are some other shapes in your house?
Instructional Strategies and Plan:
Question and Answer
Think Aloud
Higher Order Thinking
Real World Application
Activating Prior Knowledge
Visual-pattern blocks, posters, overhead visuals
Auditory-verbal instruction
Tactile-manipulatives
Materials: Polygon Scavenger Hunt Worksheets, math textbook, graph paper, pencil, crayons, colored pencils, pattern blocks, overhead worksheets and projector
Interdisciplinary Connections:
*Reading-vocabulary and making predictions
*Technology- overhead projector
Assessment Strategies:
*Formative Evaluation: teacher observation and Polygon Characteristic
Worksheet
*Summative Evaluation: Graph presentations and Polygon Characteristic
Worksheet
Correctives/Remediation:
*Preferential seating, small group instruction, Think, Pair, Share approach, provide a “characteristics word bank” for the Polygon Characteristic worksheet, SIOP vocabulary sheet (for any LEP/ESL)
Extensions/Enrichment:
*Add three-dimensional figures to scavenger hunt, design and create a
geometric picture (animal, monster, flower, building, etc.).
Special Accommodations:
*Description of the Special Needs student selected:
Learning Support- student has been identified as L.S. in
mathematics. Student has an average IQ, but is
working below
potential.
*Accommodation to use with this student:
Send home pattern blocks
Preferential seating.
Provide Polygon Characteristic Worksheet with given attributes.
