Unit Conversions Jeopardy!

• Rules– Everyone not at the board needs to work the

problems out on their own– You must show your work and include units– Team members may help, but you only get half

points– You may use your reference sheet, for half points– Until all 100-300 questions are gone, you cannot

pick 400 or 500 point questions
