Includes 3 subtraction rules and title. Can be copied and given to students to keep in their math notebook or at their desks. This complements the Subtraction Rules poster product in my TpT store. I was introduced to this “poem” years ago by a student teacher. She found it on Pinterest. I would love to give credit to the writer, but unfortunately the author is unknown to me. I revised the poem to include the mathematical terms subtract and add.
