2015 Excellence in Mathematics ContestThis is the Team Project from the 2015 Junior High Excellence in Mathematics Contest at ChandlerGilbert 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.

Nana's Lemonade  Dan Meyer Three Act TaskIn a brief video, students are confronted with the situation of a person squeezing a lemon slice into a small cup of water. Then a "big gulp" cup is placed next to the smaller, lemon filled cup. By asking the question, "How many lemon wedges do you need to add for the same lemony taste?" students will begin to experiment and mathematically determine the answer.

How Big or How Little?This activity is designed to have students think about what it means to “keep it in proportion” – a very common phrase, but what does it mean?

Sugar Packets  Dan Meyer Three Act TaskThe question is simple: How many sugar packets are in a soda bottle? The lesson hooks students immediately with the initial video clip of a man sitting in a restaurant downing packets of sugar oneafteranother! The mathematics involved is proportional reasoning.
