This is an awesome activity to really surprise your students! They are asked if they want to make money by washing dishes/cleaning up kitchen each day for 5 years starting at $.01 a day and the amount will be doubled each day for one month, and after that first month they will work the rest of the 5 years for free! Seems crazy right? Well, have them do the math!! All you need is this printable activity with instructions and record sheet. They will be amazed while doing estimation, advanced computation, and understanding the power of doubling!
