NCSM: Equity, Mathematics, and Mindset
with Tim Hebert
- Pass out the Graphing Stories Worksheet.
- Play the beginning of a video from Graphing Stories.
- Pause at about 10 seconds to allow participants to set up their graphs.
- Tell participants they will have two times to sketch their graphs – once at full speed, and once at half speed. No one’s graph will be exactly correct – the point is to think about what the graph means, not to be perfect.
- Note that even the official answer is just a sketch and is only so accurate. Allow participants to view the answer and compare it to their graphs.
- Pause the video to ask questions about the “answer” graph – what parts, pieces, or intervals do you see? Where is the graph increasing, decreasing, maximum, minimum? What parts of the video do those parts of the graph correspond with? What parts of the graph are more like lines, and what parts are more like curves? What do those shapes tell you is happening? What does the slope of a part of the graph tell you? How would the graph be different if…?
