## Reflection: High Quality Task Arithmetic Series - Section 3: Find Someone Who

To really make "Find someone Who" work you need to have a good classroom environment established.  I found this out doing this activity earlier in my career.  Students may be reluctant to pair up with another student they don't know.  In order to enable them to feel comfortable I try doing various Kagan team and class building strategies.  Some are my favorites have nothing to do with math but just building those relationships.  I think it's important to remember that establishing a positive classroom environment is just as important. Here are a couple of examples of class building activities that I use throughout the year:

1) "Balloon - One random fact about me"

Have students write one random fact about themselves on a slip of paper.  It should just be something fun like "my favorite candy is grape Laffy Taffy".  Students put the slips into a balloon and blow up the balloon.  The students then throw the balloons around the room until I call stop.  Each person grabs a balloon.  One students starts (one at a time) to pop the balloon and read the paper inside.  As a class we decide who wrote the fact about themselves.  That student then pops the balloon they have and we keep going in this pattern until all balloons are popped and we all know something extra about each other!

2) Make me laugh

Split the class into 2 teams and have them line up on facing each other leaving a space in between them.  Students take turns walking down the middle of the line.  The opposing teams job is to try to make the person walking down the middle laugh.  If they laugh they join the opposing teams line.  If they don't they stay on their team and go to the back of the line.  The other team then sends the person in the front of the line down the middle and the process repeats until everyone is on one side of the room.
