Fraction Plates

Fraction Plates lesson plan

Using knowledge of fractions, students will create a visual illustration of fractional parts with the aid of Crayola® Dry Erase Crayons.

  • 1.

    Prior to engaging students in this activity, they will have been exposed to basic fractions and how to draw fractional parts using a compass. Review how many degrees are found in a circle, half circle, and quarter circle. Students practice using a compass and protractor.

  • 2.

    To illustrate their understanding of fractional parts, students will create Fraction Plates. This activity begins with a plastic plate, a permanent marker, and a recycled CD to use as a circle template. Distribute each of these materials to students, as well as a compass, protractor, and ruler.

  • 3.

    Using the permanent marker and recycled CD, ask students to draw a circle on their plastic plates.

  • 4.

    Switching to Crayola® Dry Erase Crayons, students create representations for halves, fourths, sixths, and eighths. If there are sufficient plastic plates available, students may use one plate for each fractional type. If not, students create a requested fraction, review for accuracy, then erase for the next challenge using the E-Z Erase Mitt to wipe off Dry Erase crayon.

  • 5.

    Continue practicing. Challenge students with other-than unit fractions (such as 3/8, 6/5, etc.).

Standards

  • LA: Read with sufficient accuracy and fluency to support comprehension.
  • LA: Produce clear and coherent writing in which the development, organization, and style are appropriate to task, purpose, and audience.
  • LA: Engage effectively in a range of collaborative discussions with diverse partners on grade level topics, texts, and issues, building on others' ideas and expressing their own clearly.
  • LA: Report on a topic or text, tell a story, or recount an experience in an organized manner, using appropriate facts and relevant, descriptive details to support main ideas or themes; speak clearly at an understandable pace.
  • MATH: Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators.
  • VA: Intentionally take advantage of the qualities and characteristics of art media, techniques, and processes to enhance communication of experiences and ideas.
  • VA: Select and use the qualities of structures and functions of art to improve communication of ideas.

Adaptations

  • Possible classroom resources include: The Wishing Club: A Story About Fractions by Donna Jo Napoli; Full House: An Invitation to Fractions by Dalye Ann Dodds; The Lion's Share by Matthew McElliqott
  • Working in small groups, students create original word problems involving fractions. Groups share their original problems with classmates who use their fraction plates to assist with finding solutions.
  • Students work in teams of two. Use the Fraction Plate concept to each divide their circles into the same fractional parts, such as sixths. One student might fill in 5/6. The second team member might illustrate 3/6. Add and find the sum; simplify your answer. Subtract and find the difference. Express answers in simplest terms.
