Whack A Number

 Students were given a mole number line.

 I rolled a die on the Mimio Board and had the students either hit 1 more or 1 less.
The had to yell out what number they were whacking.

The students made a head-band that read "Whack A Number"

The "Whackers" are made out of a pool noodle and a sharpened pencil.
