Every year Americans spend lots of money on Halloween and Halloween costumes. Use our updated 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.
