Our engaging Polygons Lesson Plan explores all things polygon and prepares students to define polygons, identify the different types, and correctly name various-sized polygons. Leverage creativity as students create a pneumonic for various polygons. The hands-on activity demonstrates how a new shape is created by connecting the sides of polygons, as well as enables students to practice identifying the figures inside of the created shape. Generalize the concept in a fun, meaningful way as students design a floor plan using three different polygons.
Sample Classroom Procedure / Teacher Instruction
- Display a regular triangle and square. Ask students what the two figures have in common.
- List student’s responses. Next, display an irregular triangle and a rectangle. Ask students to contrast them with the regular figures.
- List their responses. Finally, draw a figure with a curve, but not a circle, and an open figure. Ask students to contrast them with all other figures.
- List all responses. Allow time for a discussion. Introduce polygons.
- Distribute Polygons content pages. Read and review the information with the students. Give students time to think of a pneumonic device for heptagon, and/or names of the other polygons. Save the final question for the lesson closing. Use the additional resources to enhance understanding.
- Distribute Activity page. Read and review the instructions. Distribute the necessary supplies. (Tape or another adhesive or device may be used to connect the sides of the polygons.) Allow a sufficient amount of time for students to complete the polygons.
- Once completed, the polygons can be hung on the Polygon Lines in the classroom.
- Distribute Practice page. Check and review the students’ responses. Distribute the Homework page. The next day, check and review the students’ responses. For the final section, display the figure and identify the figures inside the shape.
- In closing, ask: For the house of your future, what polygon would you use as part of the design and why?
- Allow for responses and discussion. Distribute a blank white piece of graph paper or plain white paper. Give students a set amount of time to design a floor plan for a future house using at least three different polygons in the drawing.
- Once complete, the students will share and compare their drawings with classmates.
