How well can you predict your candy haul? - Students consider how to determine their best predictions of their candy haul.  The math ideas of measurement error and percent error are introduced.  Students then predict their own Halloween candy collection numbers and compare their predictions to their actual haul using measurement and percent error.

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.

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.

Every year Americans spend a lot on Halloween and Halloween costumes. In this year of Covid restrictions, the numbers of people going to Halloween parties or trick-or-treating has gone down.  But people are still celebrating the holiday.

Use our current data on Halloween spending in America to engage your students in an analysis of the ratios and percents of population, participation, and money spent in honor of October 31st.  This activity takes kids through finding parts of wholes as well as ratio, percents and proportion problems.  Beware: the tasks in this activity involve some large numbers as well as some challenging fraction/ratio/proportion problems.
