I gave my Algebra 1 students a “One Incorrect” activity from Greta Bergman to give them some extra practice with evaluating expressions.

Students had to evaluate expressions until they found the one that didn’t equal 36. Students are always eager to get their work checked when they get an answer that isn’t 36.

Usually, I find some error in their work, point it out to them, and send them back to re-work the problem. So, they end up getting LOTS of practice!
