I notice:
Raul needs to be at the bus stop by 7:30.
He needs a total of 50 minutes to get ready.
He needs to be up at the latest by 6:40 if he wants to make the bus.
I wonder:
What time he gets up?
How often he misses the bus?
What happens when he misses the bus?
What kind of question will be asked for this problem?
How long the bus ride is.
What time school starts.

Please share your noticings and wonderings about this scenario:

Time to Get Up

Raul needs to be at the bus stop by 7:30 am to catch a ride to school. It takes him 15 minutes to get dressed, 20 minutes to  eat breakfast, 10 minutes to walk his dog, and 5 minutes to walk
to the bus stop.

On Monday, we will post examples of 5th grade students’ noticings and wonderings and the full problem.

Below is student work from the most recent time the Math Forum featured the “Filling Glasses” PoW. As PoW Planet teachers have their students submit to “Filling Glasses” they may choose to share some of that work with the world. We’ll link to it here. In the mean time, tell us what you notice and wonder about Max and Taylor’s work below.

Taylor, age 13

The answer to the problem is that graph 1 belongs to glass A, graph 4 belongs to glass B, and graph 3 belongs to glass C. We found this out by looking at the graphs and the glasses and seeing the pattern between the two. We did this by comparing the shape of the glass and the line in the graph. That is how we figured it out.

The solution is that glass A goes with graph 1, glass B goes with graph 4, and glass C goes with graph 2.

Glass A goes with graph 1 because it is narrow, then wide, then narrow.  Glass B goes with graph 4 because it is narrow then wide.  Glass C goes with graph 2 because it is wide, then narrow, then wide.
