What This Standard Means
What Students Need to Do
- Students connect each operation sign to an action: putting quantities together or taking part away. They choose and write the correct sign in number sentences.
What Mastery Looks Like
- Students correctly name each sign and explain the action it represents. They place the correct sign in an equation after seeing a model, picture, or short story.
Common Misconceptions
- Students may confuse the two signs or treat them as decoration. They may choose a sign by guessing instead of noticing whether quantities join or separate.
How to Assess It
- Exit ticket: Fill in each blank with + or -: “6 cubes, get 3 more: 6 __ 3” and “9 cubes, give away 4: 9 __ 4.”

Ways to Teach It
Give pairs counters and operation cards; students model 6 + 3 and 9 - 4, then place the matching card.
Show 7 + 2 and 7 - 2; ask students to explain how the sign changes what they do.
Play Sign Sort: students draw an equation card and place it under a plus or minus heading.
Use a snack story: five crackers gain two or lose two, and students choose the sign for each event.
