What This Standard Means
What Students Need to Do
- Students compare words such as possibly, probably, and definitely. They tell which word shows more certainty and choose one that fits a situation.
What Mastery Looks Like
- A student can order those words from least to most sure. They can explain why probably fits a prediction better than definitely when the outcome is still uncertain.
Common Misconceptions
- Students may use probably and definitely as if they mean the same thing. They may think possibly means something is likely to happen, rather than that it could happen.
How to Assess It
- Exit ticket: Put possibly, probably, and definitely in order from least to most sure. Explain the difference between probably and definitely.

Ways to Teach It
Give pairs three word cards and have them place possibly, probably, and definitely on a taped line from least to most sure.
Ask, 'If Sam says the bus will probably arrive soon, how is that different from definitely?' Have students write one sentence.
Play certainty swap: read 'It will possibly snow,' and ask teams to replace possibly with a word that shows greater certainty.
Show weather forecasts with 20% and 80% chances of rain; have students choose possibly or probably for each.
