Pdf version as well as the word document is included.
Print the worksheet on card stock and laminate for continued use. Or print a copy for each group to write their work on.
Students have to match up the bottle caps with the correct radius or diameter and place them with the correct area or circumference.
Write each solution (from the key) on a bottle cap. Great way to recycle!!
Perfect review activity or used to celebrate the upcoming pi day!
I use this as a timed game for friendly competition.
