I LOVE projects! I love that they are another way to assess students and gives those students who are weak test takers another option to show what they know. What I do not love is those students who choose to not complete any project and therefore hurt their grade even more....anyway.... We have switched our 9th graders in Fulton County to Common Core and the county has given us "blueprints" to walk us through each unit. Each blueprint comes with multiple resources that are appreciated! I came across this Mathemagic activity and turned it into a project for Unit 2. (I did not create this, I simply used it!) Students have to create a "math magic" trick where contestants are asked to choose a number and then operate certain steps on that number to get back to the original number or get to a certain number. A great way to introduce the project is be opening with... 1) Choose any nonnneagtive number... 2) Square your number 3) Multiply the result by 9 4) Take the square root of the result 5) Add 15 to the result 6) Divide the result by 3 7) Subtract 5. It's your original number! I wish I had a magians hat for the occasion...oh well... Students had to do the following with their trick: 1) Describe in words 2) Show an example # 3) Show why the trick worked with "x" 4) Justify each step (this showed students that whatever they did they had to undo!) The biggest weakness was showing why the trick worked with the general example "x." They enjoyed it and we had fun taking 510 minutes for a few days for the students to amaze their classmates with their tricks!
