Act II - What information would be helpful to figure out how many 1/4 teaspoons you need?  How many 1/4 teaspoons are equivalent to a whole teaspoon?  How can you visualize this?  What math models this problem?  If helpful check out this online fraction bar tool.

The Iditarod race will be different this year

This "Last Great Race on Earth" will start on Sunday, March 7th at 2pm near Willow, Alaska.

The race route has been changed to be safer for all those involved.  Each checkpoint will be visited twice to reduce the number of volunteers and staff needed to serve the dogs and mushers.

If you were a musher, how would you rethink your plans?

John Urschel, retired Baltimore Raven and Black mathematician

John Urschel is a young man with several seemingly disparate characteristics and talents.  He is an athlete and a mathematician and he is a black man and a mathematician.  He loves what he does and he is good at it all.

In this activity, students can learn about this mathematician and retired pro football player as they read to create a timeline of his life and accomplishments.  They compare his milestone to  the milestones that are usually met in schools.

At least the days are getting longer

What's your guess?  How fast are the number of daylight hours changing each day?  Are the changes dramatic or subtle?

Students make guesses; compute how long, on average, the change in daylight hours should be; and finally understand the variability in our year of daylight hours.
