How many pies would this behemoth make?

giant-pumpkin2Let your students marvel at World Record winning giant pumpkins as they use proportions to calculate the quantities of pumpkin puree and the number of pumpkin pies that could be made from one of these giants.  To introduce the task you might show this cool time lapse video of a giant pumpkin from planting to harvest.

Use your student’s Halloween enthusiasm to do a study on volumes.  We’ve created an activity that asks students to calculate the volume of candy containers that are silly and intriguing.  Skip the cone and the sphere to make this activity more useful for 5th or 6th graders or include the whole activity to challenge with a little bit of percent work.

In 2001, J.K.Rowling (the author of the Harry Potter series) wrote Fantastic Beasts and Where to Find Them. The movie of this book will open on November 18th, 2016.  This will be the first in a series of three movies that are meant to take place 70 years before the Harry Potter series began.

To bring attention to this debut, iMax theaters will be presenting a solid week of the 8 previous Harry Potter movies starting on October 13th, 2016.

"Beasts" is produced by David Heyman, the same producer that created the other Potter movies.

In this activity students use the average cost of making a Harry Potter movie to estimate the cost of creating the "Beasts" movie. The task is open, in that it asks students to analyze central tendency, using either median, mode or mean.  Which is the best predictor of the cost of making this new movie?  

Columbus and navigation

nina-picThe Niña

Columbus Day is a bit of an enigma that used to be celebrated all through the Americas.  Columbus's mission and arrival are now thought to have not been a noble endeavor in the way that indigenous people were treated.  Now, many states no longer celebrate Columbus Day.

This post is about imagining sailing off into the West, into an empty looking ocean, to find what your captain believes is a good route to the Indian subcontinent?  Sailing West was a huge navigational feat.  Fortunately Columbus's ships experienced good weather but they landed in the Caribbean ... not southern Asia.

Use some of what we know now about navigation to examine this trek and do some reasoning and experimentation with the data.
