CCSS.MATH.CONTENT.3.MD.D.8 Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.
CCSS.MATH.CONTENT.4.MD.A.3 Apply the area and perimeter formulas for rectangles in real world and mathematical problems.
⏰ LESSON TIME
In this lesson, students will learn how to compute perimeter of different polygons using multiplication and apply those skills in game-based practice problems. They will then learn about different Indigenous traditional dwellings. The lesson ends with students contributing to and solving problems that integrate the reading on dwellings and perimeter in an online assessment.
📲 TECHNOLOGY REQUIRED
Device with web-browser (Chromebook, laptop or desktop computer); or iOS (iPhone/iPad) with Google Drive apps.
1. Play GAME: Making Camp Premium
For 15 minutes, have students play the game Making Camp Premium.
ALTERNATIVE: Perimeter is also covered in the second half of Spirit Lake: The Game, which is currently available for Windows and Mac computers.
2.READ: Home, Sweet Home: Tipis, Hogans, Wigwams and More
Read this short post about traditional dwellings of Native American tribes from different parts of the United States. It can be read aloud as a group or individually. (Estimated time: 7-10 minutes)
3. Discuss how to Compute Perimeter
This Google slides presentation reviews the definition of a polygon and perimeter and provides the formulas for finding the perimeter of a rectangle, square and triangle with examples for each. You can review it together in class or online, copy to Google classroom to assign to students or print out to send home for students without Internet access. (Estimated time: 5-10 minutes)
4. Testing understanding : Perimeter in Action
This activity draws from the “Home, Sweet Home” reading and lessons on perimeter to have students apply their understanding of how to compute the perimeter of rectangles, triangles and hexagons using multiplication. Get the Google slides presentation here. Students contribute numbers to create multiple problem options.
(Estimated time: 10 minutes)
