Add histogram activities from Joy

[flannery-denny]

Histograms activity I did before teaching shape. I would give students a set of histograms cut out (we could come up with better ones)and ask them to sort them into 3 groups and glue them onto poster paper. They would fill out this worksheet to explain why they grouped them the way they did. Then the groups shared out. It is a great way to start them identifying shape before talking about the actual vocabulary. I loved it.

Other Histograms Activity
It is a bit different from what got added to the lesson. The students create a histogram for one shape. Rotate. Write a scenario for the next. They already had a discussion about the first shape and probably had scenarios in mind, so by rotating and writing on the next, this catches them off guard, if you will, as I don't tell them they will be doing that. Then they have to really look at the next shape from ground up and write a scenario. 3rd section is saved for boxplot lesson - where they will rotate and draw boxplot on the 3rd shape to match that scenario and histogram. If teacher does not plan to do boxplots, they can rotate and have students write another scenario on the 3rd shape.

I think it forces more critical thinking to rotate before they brainstorm scenarios.

I also like the connection to boxplots.
