# The Wave

Standard

The class that challenged me the most yesterday is the one that made me smile the most today.

A snippet from their class…Yes I asked quest I ns, but so did they!

We collected data doing “The Wave.”  We talked about what we noticed.  Then I asked, who would want data like this and how would they use it?

Student:  Maybe someone who wanted to know how long it would take all the people at a ballgame to do the wave.

So we guessed how long it would take 882 students.  And discussed different ways to make a prediction based on the data.

They decided to calculate each trial’s rate, then average them.

Another student asked, how much space would it take for everyone to line up?

I don’t know. How could we figure that out?

Student: Let’s see how much space we take up.

20 ft for 9 students. (Yes, that’s how small my class was today).

Group 2:  K got an answer of 24 feet.  A: K, I disagree because if 20 feet is for 9 people, 24 isn’t much larger and that’s way too small for 882 people.  So they reworked.

Group 3: J: I got 1960 ft.  I asked the others, how’d J get this?  And they explained it to me.

Group 1: 16 miles.  (Huh?)

And they shared their work. (20)(9)=180 (882)=79860 feet.
S: I don’t understand where 180 came from?

C: can you explain why you multiplied 20 and 9?

A: what if you tried dividing those numbers and see if that works?

I loved how A suggested to his team that they split 882 students into groups of 9 and each group gets 20 feet.

This may be too elementary for some folks reading.  But the fact that a class of students who despise math, who “can’t do math” did their math just fine.

They not only explained their reasoning but respectfully asked questions to critque the thinking of others.

I want them to experience success.  I want them to know I value their thinking.  I want them to learn. I want to challenge them. I want them to smile when they enter my classroom.

Yes, the class that challenged me most yesterday made me smile today.
