Halloween Mystery Solved

Our 4th grade math teachers got together and came up with a clever way to get kids excited about learning math, and threw in a little Halloween spine tingler for some added fun.

Mrs. Cook, Freeman, and Hertel not only came up with the math mystery, staged the “crime scene,” and called Officer Wilkey to come in and help the students solve the crime.

Because students are currently studying place values, they had to figure out which member of the “Petrifying Place Value Gang” created the big mess in the classroom. Students worked in detective teams to solve math problems to narrow down the suspects. Then they worked together as a whole class to narrow it down to one suspect to be arrested by Officer Wilkey.

The fun activity taught students place value and notation practice, helping students better understand number composition, value assignment by place, and converting between expanded and standard forms.
