What This Standard Means
What Students Need to Do
- Students count each object in a small group once. They say how many there are altogether, even when the objects are moved around.
What Mastery Looks Like
- A student counts six counters in a row and says there are six altogether. When the counters are moved into a circle, the student still says six because none were added or taken away.
Common Misconceptions
- Some students think the final number they say names only the last object they touched. Others think a spread-out group has more, or count an object twice when the group is scattered.
How to Assess It
- Place six buttons in a row and ask, "How many buttons?" Spread them apart without adding any, then ask, "How many now? How do you know?"

Ways to Teach It
Give pairs seven counters to count in a line, then have them move the counters into a circle and name the total.
Show five dots in a row and five scattered dots; ask, "Which picture has more? How do you know?"
Play a partner game: roll a die, count that many blocks, scramble them, then have a partner name the total.
At snack, count five cups on a tray, place them at different seats, and ask how many cups are set out.
