Type: Mini-lesson

Theme: Numbers

Grades: 5, 6, 7, 8, 9, 10

Learning Target: Students will construct rational fractions using a visual model.

  1. Warm-up. Show the following graphic. Ask what fraction of the whole does the blue, red, and/or purple represent?
  2. Explain that parts can be divided by the whole.
  3. Show the following graphic, which represents infinite squares.
  4. Provide a PowerPoint presentation for students to construct their rational fraction. Duplicate the page, so that groups of two can work on the puzzle. Older students will attempt to produce a rational fraction using an infinite pattern.
  5. Demonstrate using Desmos:
