This activity requires NO PREP, student and teacher documents included.
It is a riddle worksheet where students have an answer bank and they use that to solve a (slightly cheesy) joke. Kids like this activity because it makes the math meaningful and FUN. Teachers like it because the answer bank gives students a tool to self-assess.
Because of answer banks for students and answer sheets for adults, this activity is great for home, school and special education!
In this particular worksheet, students learn about summation notation and how it relates to arithmetic and geometric series.
