What This Standard Means
What Students Need to Do
- Students put two groups together and find totals up to 5. They say or write sums for problems such as 2 + 3 and 4 + 0.
What Mastery Looks Like
- A student answers additions with totals up to 5 quickly and correctly, including sums with zero. They can show 3 + 2 with fingers or counters and explain why the total is 5.
Common Misconceptions
- Some students count only the second group instead of both groups. Others start counting on at 2 for 2 + 3 and stop at 4 instead of 5.
How to Assess It
- On an exit slip, give 1 + 3, 2 + 3, 4 + 0, and 2 + 2. Ask students to write each sum, then explain one with a quick drawing.

Ways to Teach It
Give pairs five counters and a five-frame, then have them show 2 + 3 and 1 + 4 and say each total.
Ask partners to explain how they know 3 + 2 is 5 without counting every object, using fingers or a five-frame.
Match addition cards with sums up to 5 to numeral cards, then swap cards and play again.
Place two crayons on a table, add three more, and ask students how many crayons are there now.
