This is a great review project for the end of the year or to review before state testing! Students choose their favorite number, then have to answer all kids of math questions using that number.
create a triangle that has an area of your number
write an inequality where your number could be an answer
write a list of numbers where your number is the mean/median/mode
Then, the students create a poster with all the math they created.
Directions sheet is completely editable. There is also a completely filled in sheet to serve as an example.
