How do you represent addition in a strip diagram?

Back

In a strip diagram, addition is represented by combining two or more strips to show the total length or value.

Front

How do you represent subtraction in a strip diagram?

Back

In a strip diagram, subtraction is represented by removing a strip from a total length to show what remains.
