This is the Team Project from the 2015 Junior High Excellence in Mathematics Contest at Chandler-Gilbert Community College. It involves lots of open ended problems from many mathematical areas: Find the weight of a snowman (geometry, proportional reasoning) Find how long it takes ice to form on a lake (rate of change, awkward units) Questions about the amount of mining done in Northern Minnesota (proportional reasoning, conversions) You can use just one part or all parts depending on the audience and the purpose.
