Includes 3 subtraction rules and title; each on its own page. Can be printed, cut and put onto a poster board as seen on the cover page. 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. Compliments the student page that can be found on my site.
