This is a grouping of 4 posters to be used when teaching regrouping with both addition and subtraction. Each colorful poster has a large diagram (sample problem) and a catchy poem to help students remember the steps. *I did not create these poems, but I know they have been used for many years by teachers and students alike. I remember using them when I was a student!
There is a poster for addition w/ regrouping, subtraction without regrouping, subtraction with regrouping and subtraction (with multiple zeros in the number) with regrouping.
Just laminate and post in the classroom! A great resource!
