Reflection: Debate The Punk Prank Payback - Section 1: Intro & Rationale


Interestingly, the labeled floor plan that we use in this lesson helps my students figure out whether they should add or subtract the component side measurements to calculate the missing measurement. In more abstract shapes my students will still be confused about this, but today I didn't see them making a mistake with this calculation. I am not yet sure why that is. Maybe the familiarity helps them make sense of measurements and they know, for example, that the bathroom wall will likely be shorter than the kitchen wall.
