If you are using the workbox system, I suggest you put the Student Copy of the Instant Challenge in the box upside down with a sticky note that says: "Instant Challenge - No Peaking" (The goal is for them to use their imagination while thinking and working quickly to find a solution). Then you will have the challenge materials at a "station" with the materials list as indicated in the challenge. You could also include the timer, since it will be used in each challenge. Keep the challenge materials hidden until the time of the challenge.
I will post our solution, give you an opportunity to link up your solutions next week and and post the next instant challenge. I hope you will join us!
Tip of the week: Teach your children that every item given to them in an Instant Challenge may have many uses. They should always be looking for alternative or unusual ways to use common items.
