Yesterday’s post reminded me of an activity we created for a recent department head meeting/pro-d workshop.
In pairs, DHs were asked to take a photo (with an iPad — sorry, Timon) of each of the following:
- a perfect square
- the use of a referent to determine the linear measure of an object
- a positive & negative slope
- a non-linear relation
- an irrational number
- similar 2-D shapes or 3-D objects
- angles formed by parallel lines and a transversal
- a contextual problem that involves the sine law or cosine law
- a z-score of ±2
- elements in the complement, the intersect, or the union of two sets
- a stranger engaged in math
A fun break from a wrapping our heads around a transformed competency-based curriculum.
In my classroom, I’d probably prefer a more narrow focus — a specific concept over a general math activity. For homework, have students take a photo of parallel lines and a transversal. In class, ask What do you notice?™ Christopher Danielson’s students — future elementary teachers — were asked to photograph a composed unit, which led to a lovely classroom discussion. Dan Meyer kicks the find a positive & negative slope challenge up a notch by holding a steepest stairs competition.
Any other ideas for challenges/activities?
