For example a problem might have -6 2 and if students say it is 36 the final answer will equal what’s in the center. For the problem that doesn’t work, I tried to create a problem that if students make a common error, the expression still equals what’s in the middle. It was easier to make 7 problems that all evaluated or simplified to the same answer than I anticipated. I created similar versions for evaluating expressions and order of operations with integers that I used last week in two different classes. I don’t have to worry about remembering an answer key for students! I like it because students know that 7 of the answers will be the expression in the middle. All but one of the expressions simplifies to 5n + 3, and you need to find the expression that doesn’t and show that all the others do. I was introduced to this type of a worksheet this summer by Sara Van Der Werf.She had us do the one below at one of her PD sessions this summer. Last week in two of my classes, I assigned a worksheet like this: If anyone has a system that works for them, please share! I am also terrible at remembering to upload answer keys to Google Drive for students. I want them to be able to check their work to know if they’re doing it right, but I go back on forth with whether I should just give students answers or worked out solutions. I want homework to be useful to students. One of the things that’s a constant struggle for me every year is giving students access to answer keys for homework problems.
