  1. Orienteering: Blazing Our Trail

  2. Session Goals • Develop a strategy to create open tasks related to proportional reasoning in order to differentiate instruction. • Develop strategies to create appropriate scaffolding questions.

  3. Before/Part 1/Minds On • Look around the room. Compare the number of people with glasses on right now to the total number of people in the room. • With your group, identify as many other ratios as you can using all of your fellow campers.

  4. Before/Part 1/Minds On • Get up and look at the glyphs around the room. What other ratios do you see? • Sketch a pictorial representation of one of the ratios you identified in your journal.

  5. During/Part 2/Action • Remember on Monday night, when we were scratching?

  6. During/Part 2/Action • On a typical May 24th weekend, Joyce noticed that both her arms were covered with black fly bites. Cathy said “I think I have twice as many as you do!” How many black fly bites might Cathy or Joyce have? • Review Marion’s fail-safe strategies for creating an open task. Does the problem that we introduced on Monday evening meet the criteria? • Think-pair-whole group share

  7. During/Part 2/Action Two ratios are “almost but not quite” equivalent. What might they be? • Identify the big ideas and the lesson goal for this open question.

  8. During/Part 2/Action • Solve this open question on chart paper in your glyph group. Show your thinking: Two ratios are “almost but not quite” equivalent. What might they be?

  9. After/Part 3/Consolidate Tweet About Open Questions! • With a partner, create a tweet to send to a friend (140 characters or less) to explain a strategy that you could use to create an open question.
