### Decimal Operations: Multiplication Would You Rather

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!
