Lesson objective: Apply the method of decomposing a figure.

This lesson provides an opportunity for students to apply their knowledge and understanding of decomposing figures into regions of known area to a real-life situation. Students are asked to create a pattern for a pool sidewalk and determine the area that will be covered by each color and the cost for their design.

Key Concept students will use:

  • Area is additive, meaning the area of a figure is the same as the sum of the area of non-overlapping regions of the figure.

Skills students will use:

  • finding the area of a rectangle (Grade 4, Unit 2).
  • decomposing a figure into rectangles.

Students engage in Mathematical Practice 2 (Reason Abstractly and Quantitatively) as they determine which color blocks will provide a pleasing design and keep the cost of the project down.

Key vocabulary:

  • area
  • decompose

Special materials needed:

  • Graph paper may be helpful for some students.
