LeBron_James

Lebron recently left the Miami Heat to go back home to the Cleveland Cavaliers where he began his professional career.  Lebron is arguably the best player in the NBA and a tremendous addition to a team … a real difference maker.  In this activity students read graphs and use measures of central tendency as they compare the records of the Miami Heat and Cleveland Cavilers with and without Lebron.  How many wins per season can we expect from the Cavilers now that they have Lebron back and just how many wins is Lebron worth?

Cheesy Goldfish crackers

In this activity students do a little comparison shopping as they determine which size Goldfish product is the best deal.  Students are introduced to the ratio table as a tool for determining equivalent ratios and comparing different rates.  Students graph cost per ounce relationships and answer a few open questions, which should lead to some good thinking and discourse in this authentic math activity.
