Students will be able to illustrate products of a fraction times a fraction with an area model.

The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.

(5 minutes)
  • Show your students a T-chart with "area" for one column and "model" for the other. Ask your students to turn to a neighbor and tell them something they know about each word.
  • Have students share out their ideas with the whole class and note their ideas in the T-chart.
  • Draw a single column chart titled "Area Model" and repeat the previous inquiry and share process.
  • Explain that today's lesson is about a particular area model: a rectangular illustration often used to show products or sums of repeat addition. (Add this explanation to the area model chart.)
(10 minutes)
  • Hand out and preview the four-step procedure on the Area Models: Fraction Products 1 worksheet with your students.
(10 minutes)
  • Lead your students through exercises 1 ,3 ,5, and 7 of the Area Models: Fraction Products 1 worksheet.
(10 minutes)
  • Assign exercises 2, 4, 6, and 8 of the Area Models: Fraction Products 1 worksheet to your class.

Support:

  • When leading your class through guided practice, allow students to read the instructions aloud and hand off to other students to guide the class through each exercise.
  • As each exercise is a stage of the four-step process, pause to answer any clarifying questions along the way.

Enrichment:

  • As an extra challenge, have students exchange one of the factors in an exercise for an improper fraction.
  • It's convenient to snap pictures of student work at different stages. Using student samples can be helpful when assisting others or for explanation references.
  • Phone camera snapshots can be displayed quickly under document projectors, or downloaded into digital documents for later reference.
(5 minutes)
  • Show your class an area model for ¼ x ⅝.
  • Have students tell you the equation and explain its relationship to the area model.
  • Share with your students that they will be reviewing peer work and to think of a related compliment or question as they do so.
(15 minutes)
  • Share with your students that they will be reviewing peer work and to think of a related compliment or question as they do so.
  • Hand out two sticky notes per student. Perform a "silent gallery walk" review of student work by:
    • Having students place their work on their desks.
    • Stand quietly and walk around to view each other's work.
    • Offer a related question or compliment using the sticky notes (allow up to two notes per work displayed).
    • After the gallery walk, have students review their feedback and place their sticky notes on a poster chart or board labeled "feedback." (These notes can be reviewed later for a lesson of providing effective feedback!)
    • Collect student work to review later for student understanding.
    • Display some of the pictures you took of student work and allow students to discuss which stage in the problem solution each picture refers to.
