With our decimal multiplication today, I posed the Would You Rather question:
I posted this activity on Google Classroom along with a Google Doc for the 3 Act Math information.
Using the information given from the prompt, students soon discovered that the plans were of equal value, with the exception of Option E. It was a total savings of $.01! We even discussed the fact that trading in your phone early saves you no money, you are still expected to pay the entire amount!
During the process of multiplying, I wandered the room to ensure success. I found common multiplication errors, forgetting to bring down the zero, but I also saw misalignment errors. Students want to line up decimal points when multiplying!
