There are 15 sets of 10 equations with answer choices. I have attached a key and key with work and steps shown. I use this in my Algebra 1 class to make sure students practice solving equations and know how to show the correct steps and not just get the answer. I assign one set a week. I post them on the board on Monday and they are due by Friday. I tell my students I am grading their "work" and not just if they get the correct answer. If I can not follow their steps or their steps do not match their answer I count it wrong. If students turn them into me before Friday I will grade them and return them the next day for them to try to correct and get the right steps. As long as they do this BEFORE the due date it is fine. I do this because I am looking for mastery.
This also helps in my class so that there is never "nothing" to do. I am maximizing time on task between activities. I have found a BIG increase in my students basic solving skills because I do this.
The equations are made to gradually get more difficult each week but students will feel more confident as the weeks progress.
