Conduct a Lesson Study Cycle on Fractions

Step 4: Examine Video

Step 4 provides video to spark thinking about the design of your fractions unit.

  • To start, revisit the beginning of the 3B fractions unit (pages 57-64) and imagine how you might teach it.
  • Read over Akihiko Takahashi’s lesson plan for a series of three lessons based on this textbook segment.
  • Watch the video from Dr. T’s lessons (taught to grade 3-5 students in California). It will useful to print out the lesson plan and the table below, to have them as reference while watching.
  • Watch Lesson 1 (stopping at 8:11 and 9:42 to consider questions in the chart below)
  • Watch Lesson 2 (stopping at 4:40 and 8:40 to consider questions in the chart below)
  • Watch Lesson 3 (stopping at 13:35 to consider the questions in the chart below)If watching the video online, you can see the timecode by moving the cursor over the lower part of the video.
