Polygon Patrol SlidesUnit 4: Geometry POLYGON PATROL Identifying shapes by their attributes and tracking down the rules of geometry. Officer Training 4th Grade Math Mission Start: Prefixes Tri- Can you think of any words that start with "Tri"? Waiting for ideas... Quad- Can you think of any words that start with "Quad"? Waiting for ideas... Oct- Can you think of any words that start with "Oct"? Waiting for ideas... Training Film Watch closely. We will pause to practice. ACTIVE VIEWING Embedded media Checkpoint 1 (1:22) Prepare for the Counting Chant! Use your fingers and chant along. Checkpoint 2 (2:01) Interactive Quiz! Shout out the name of the shape before it's revealed. Checkpoint 3 (3:00) The Rules! Listen for the 2 conditions that make a shape a Polygon. The Polygon Code A shape is a polygon ONLY if it follows these 2 rules: 1 Straight Sides No curves allowed! Every side must be a straight line segment. YES NO 2 Closed Shape No gaps allowed! All sides must connect at the vertices. YES NO Polygon or Imposter? Poll the Class A B C D Think: Does it have straight sides AND is it closed? Unlock the Count Penta- ? Hexa- ? Hepta- ? Octa- ? Nona- ? Deca- ? Mission Complete You've identified the suspects. You've learned the code. Now, prove your skills on the Rule Breaker Exit Ticket! Next Step Exit Ticket Extension Police Badges
Polygon Patrol Teacher GuideOfficial Teaching Brief Polygon Patrol Grade 4 • Geometry • Attributes & Prefixes Duration 40 MIN Learning Objective Students will define polygons based on specific attributes (closed plane figures with straight sides) and utilize Greek prefixes to determine and name polygons based on their side count. Materials • Polygon Patrol Slides • Shape Sentry Anchor Chart • Prefix Power Worksheet • Rule Breaker Exit Ticket • Polygon Police Badges Mission Timeline 00:00 - 00:05 • Warm-Up: Prefix Hunt 5 MIN Write Tri-, Quad-, and Oct- on the board or use Slide 2. "Officers, we have some code words to crack. Can you find these prefixes in the real world?" Tri: Tricycle, tripod, triathlon. Quad: Quadrant, quad-bike, quadruple. Oct: Octopus, octagon, octave. 00:05 - 00:15 • Video Training 10 MIN Play the Polygons Song (Slide 3). Use the following pause points for active training: 1:22 - Counting Chant Have students stand up and use their fingers to chant along with the rhythmic count. 2:01 - Interactive Quiz Pause after "What shape is this?" before the reveal. Let the class shout the answer together. 3:00 - The Rules "Listen closely! There are two rules that every polygon MUST follow. What are they?" 1. Straight Sides • 2. Closed Shape 00:15 - 00:30 • Discussion & Sorting 15 MIN Task 1: Polygon or Not? Use Slide 5. Draw extra figures on the board: a circle, a letter 'C', a wiggly line, and a star. Have students vote by showing a "Thumbs Up" for Polygon or "Thumbs Down" for Not a Polygon. Task 2: Prefix Match Hand out the Prefix Power Worksheet. Students will match the Greek prefix to its numerical value and identifying shapes by attributes. 00:30 - 00:35 • Closure: Exit Ticket 5 MIN Distribute the Rule Breaker Exit Ticket. Students must intentionally create a "Criminal Shape" (non-polygon) and identify which geometric law it broke.

Shape Sentry Anchor ChartThe Geometry Code SHAPE SENTRY How to Identify a Polygon 1 Straight Sides No curves, arcs, or wiggles allowed. YES NO 2 Closed Shape No gaps or openings. The path must be continuous. YES NO The Prefix Decoder TRI- Prefix 3 Sides QUAD- Prefix 4 Sides PENTA- Prefix 5 Sides HEXA- Prefix 6 Sides HEPTA- Prefix 7 Sides OCTA- Prefix 8 Sides NONA- Prefix 9 Sides DECA- Prefix 10 Sides Remember: Vertices and sides can't have any breaks!
Prefix Power WorksheetPrefix Power Officer Training Worksheet Name: Date: Task 1: The Prefix Match Draw a line to match the Greek prefix to the number of sides it represents. Penta- Deca- Hexa- Hepta- Nona- 10 7 5 9 6 Task 2: Evidence Check Count the sides and write the correct Polygon Name using your prefix knowledge. Sides: ______ Name Sides: ______ Name Sides: ______ Name Sides: ______ Name "Tri is three, Quad is four, Penta five, and Hexa more!"
Rule Breaker Exit TicketCase #102 Rule Breaker Exit Ticket: Spotting the Imposter Detective Name Date 1. Draw a "Non-Polygon" (The Criminal Shape) 2. Why did you arrest this shape? Identify which polygon law was broken. Was it curved? Was it open? Explain your reasoning below. Remember: A true polygon must be CLOSED and have STRAIGHT SIDES. If either rule is broken, it's not a polygon!
