This document is intended to be used in a math interactive notebook for each student's personal use. Use these simple addition and subtraction signs for students to write words that are associated with addition and subtraction in word problems. Addition words might include "sum," "total," or "all together." Subtraction words might include "how many were left" or "difference." The students can write them all at once and use them as a reference or write them as they are exposed to the words while working through word problems. I attach these in the front cover of a "Problem of the Day" notebook where students solve one word problem a day.
