This is a great review for Algebra 1 students who have learned exponent properties (zero power, power to a power, adding powers, subtracting powers). There are a varying degree of difficulty. Some require multiple steps to simplify. I used this as a partner activity. There are thirteen different BINGO cards. I laminated these so students could use dry erase markers to cross off the answers.
The answers to the questions were on the BINGO cards. I solve the problems on the teacher answer key and then used this to ensure that students solved them correctly when they got a BINGO.
