I've tried this: This is a GREAT origami tutorial for a fox. It gets a little bit confusing, so I don't recommend it to total beginners, but ultimately it makes a cute origami fox that can stand up on its own.
Cute idea for measurement common core- do a few times a year. Read Big Dog, Little dog, and then measure each child to see how tall they are. Make a chart for display, and leave out the measuring tape for a few days!
