Junior Ninja Challenge #3

Here's the Junior Ninja challenge for this week. It is not required, but think of it as an opportunity to work with your child one on one to see if they can explain their thinking. The challenge is designed for them to find success, but it is multiple steps. They should solve one part at a time and check off each step as they complete it. They should check their work for accuracy and for completeness. All great mathematicians do.
