Fraction A Day - Day 34 Is it Half a Star?

Using a gridded playfield allows kids to see the area for different shapes. Using the Fractionator (and a playfield with gridding turned on) I was able to get the images below, which are 1/3, but are they 1/3 of the Star? Let the kids ponder this for a while, then ask "What's your unit/whole/one?"
