Sharing PencilsSarah and Michelle are working on a class project using colored pencils. Given some information about the number of pencils that Sarah and Michelle had when they started, and how some sharing of pencils has taken place, students must employ proportional reasoning skills to determine how many colored pencils the girls now possess.

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.

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?

Preheating the OvenStudents use rate of change ideas to predict how long it will take for an oven to preheat to 400 degrees. The youtube video may be used to bring drama to the lesson! A link to the video is here and also in the documents. https://www.youtube.com/watch?v=I2ooIWFAcII&list=UUiPlxONW80Z8rGpu3lSLwjg

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.

CaptureRecaptureImagine that a city employee is given the task of counting the number of fish in a city pond in a park. The “capturerecapture” method may be used to approximate the number of fish in the pond. The employee could capture a number of fish, say 20, and tag them and release them back into the pond. Waiting until the fish have a chance to become mixed with the other fish in the pond, the employee can capture more fish. If the number of fish captured is 25 and 4 of them are tagged, we can use proportional reasoning to estimate the number of fish in the pond.
