This is a task that I recently completed with my grade nines.
Before starting the task we discussed the task as a class, students were invited to ask clarifying questions, and students were given the materials at stations to measure what they needed to so that they could complete the task.
See assignment sheet attached here.Measurement In Class Assignment
Things that went well: Student engagement was high, students were focused. Interested in the task. Students discussed problems that they were having with each other. Not as many students were looking for me to check if they “got it right”.
Things that need improvement: Timing – the whole class needed to be dedicated to the activity. I spent too much time discussing the problems. In hindsight, I needed to let the class spend more time discussing the problems and take myself out of the discussion. In future, I might even record myself to explain the task, then answer questions on a time limit to give myself a time limit and not become the spoiler of great math explorations!
Now that I have photos of the built models that students worked with at stations, I would swap my images in the assignment sheet so that the models are more accurately represented on the assignment itself.
