Tricia Poulin makes some awesome moves in her #bottleflipping lesson, including this one:
Okay, so now the kicker: will this ratio be maintained no matter the size of the bottle?
Graham Fletcher offers us video of kindergarten students interacting in a 3-Act modeling task:
Itâ€™s always great to engage the younginsâ€™ in 3-Act Tasks. Iâ€™ve heard colleagues say, “I donâ€™t have time to do these types of lessons.” I hope this helps show that we donâ€™t have time to not have the time.
The students designed their own â€œMoney Animalsâ€, complete with a price, distribution, and an expected value.

Sarah Carter hosts the Mini-Metric Olympics, a series of data collection & analysis events with names like “Left-Handed Sponge Squeeze” and “Paper Plate Discus”:
After the measurements were all taken, we calculated our error for each event. One student insisted that she would do better if we calculated percent error instead, so we did that too to check and see if she was right. In the future, I think I would add a “percent error” column to the score tracking sheet.
