Areas and Volumes - 2D Shapes

Curated and Reviewed by Lesson Planet
This Areas and Volumes - 2D Shapes lesson plan also includes:

Unfortunately for young mathematicians, the world isn't made entirely of parallelograms, triangles, and trapezoids. After first learning the area formulas for these common shapes, students apply this new knowledge to determine the area of irregular shapes.

Instructional Ideas
  • Integrate this lesson into an upper-elementary or middle school geometry lesson on the area of polygons 
  • Have students to work with a partner or in small groups completing part B of the included worksheet, allowing them to discuss different approaches to solving the problems
Classroom Considerations
  • This lesson seems to be designed for use in a bilingual English/Chinese math class, but it does not require knowledge of the Chinese language
  • Despite the title of this resource, the concept of volume is not addressed in this lesson
Pros
  • Teacher notes are provided to support the implementation of this lesson
  • Includes a student handout with both the English and Chinese words for different geometric terms
  • Worksheet offers a wide variety of geometry problems that thoroughly assess students' understanding of area
  • An answer key is provided for the practice worksheet
Cons
  • None
