I received this file about 5 years ago at KCTM in Bowling Green. Kari from WKU shared it. I apologize I cannot remember her last name to give credit.
She actually used it to play a card game style activity. I copied sets onto different colored cardstock and laminated, I have enough sets we usually do groups of 3 people.
I do this activity along with Go Fish for simplifying radicals.
There are four different forms of each value. Students use calculators to match cards with same value. We create a poster as a whole class. Then notice and wonder.
I like how students develop their own understanding of rational exponents, negative exponents and radical forms. It’s a great intro activity.
