Making mathematical pizza

At the kids' school different learning activities are called "jobs."  There's a "map job" in geography, a "leaf job" in biology, a "carrot job" teaching them how to use a knife to cut up carrots, etc.  The one below is the "circle job" introducing fractions - or, as one of Xander's friends call it, the "pizza job."

Hard at work.  You can see the red pizza circle on the lower right. 

The first page of his packet: a full circle and a creatively-spelled name.  

Halves.  Bad shadow, sorry.

Thirds.

Quarters.  I don't know where he picked up the European four notation.  Or, as he calls it, "fancy fours."

And voila.  Fifths.  A nicely cut-up pizza pie.

And in another entry in the "where did this child COME from?!" files, Xander's teacher has now resorted to making deals with him: she'll only teach him more numbers if he reads a book or does sight words with her.  Otherwise he'd do math all day, every day, and ignore literacy completely!
