math wizard

My 7-year-old (who is whizzing through and about to finish his 4th grade math book), grasps most math concepts incredibly well, but we realized we need to readdress fractions tonight! He came in from feeding the chickens and informed his dad that they still had 1/3rd of 10/3rds of the container of water. Say what???

I think the statement would be totally age appropriate. I wouldn't have really even given it a second thought past the initial giggle, had I not seen him work out many much more complex fractions in the past!
