Halloween tricks and treats – 13 activities

How many houses can you get toDevelopment - It’s Halloween. Time to trick or treat.  How long will it take you to get to all of these houses?  This is a very open-ended task, counting, trick or treating strategies, distance and more.

SheetGhostMake a ghost costume from a sheet - In this activity young students can reason about the potential of a sheet, cut in a very defined circular shape, becoming a Halloween ghost costume. Notions of head diameter, sheet length, less than and greater than will all come into their reasoning.


One of my favorite foods is a burrito.  One of my favorite places to get a burrito is Chipotle.  Their food is delicious and environmentally friendly.

For Halloween 2016, Chipotle is again running a promotion and charity drive.   Chipotle is offering $3 burritos to customer who come dressed in their Halloween costumes after 3 p.m. on October 31st.  Chipotle will donate up to one million dollars to the Chipotle Cultivate Foundation.

Teachers, give your students time to ponder and discuss these questions:

  • How realistic is it for Chipolte to sell one million dollars worth of $3 burritos in one night? 
  • What more information would you like to have to decide if this is even possible? 

The Cubs


Wow!  It's been a long time coming.  The Chicago Cubs are in the World Series! The last time they won the World Series was in 1908 (For some perspective, that is the same time the first car, the Model T, was produced.)

Since 1908, how long has that been? How many players have waited? How many games or innings have gone by? How many days, minutes, seconds?  In this activity students answer some of these or their own questions

Which is the best candy deal?

135 pieces for $14.9990 pieces for $6.9995 pieces for $9.9950 pieces for $6.99150 pieces for $14.24

Clicking on any of the above images will open the image larger in a new window.

We found big mixed bags of candy at really good prices ... we think.

Students are asked to decide which would be the best deal and the worst deal on candy.  They can also create their own mixed bags.  This activity has unit pricing, philosophy of candy collecting, and Excel if you would like to use technology.  

Is the Electoral College unfair?

Show your students this really cute segment comparing how the Electoral College functions in our elections to what students think is fair and just. From the New York Times, Electoral College 101.

After showing the video consider asking your students what the grouping of students must have been for "colored pencils" to win the class electoral college?  Is there more than one possibility?  What is the minimum number of students that could have voted for colored pencils for them to still win the Electoral College.  Students then consider scenarios where a candidate wins the popular vote, but loses the Electoral College.  

How much will you make when you are president?

You can't run for President now, but heck, 2036 is right around the corner.


Being President of the United States will be quite an accomplishment and a ton of work.   But, how is the pay?  Does the job pay millions per year like the pay of some athletes, actors and musicians?

So, how much should you expect to make as president in 2036?
