What should you review before the quiz?
Reread the key facts of the lesson and the worked example. If a question is hard, go back to the matching part of the lesson, then try the quiz again. Write your work on scrap paper: most mistakes come from skipping a step, not from the idea itself.
Remember:
- Add tens to tens and ones to ones, then combine the parts.
- Regroup when the ones make 10 or more: 10 ones become 1 ten.
- An open number line adds by jumping tens first and then ones.
- Numbers can be added in any order, so group the easy pairs first.
- Add three or four two-digit numbers two at a time.
