Compare two groups of objects up to 10 each to tell which has more, which has less, or if they are equal.
Look at two groups. Which one has more? You can count both groups and compare the numbers. Or you can match them up, one to one, like partners.
If every object in one group has a partner and some are left over, that group has more. If nothing is left over, the two groups are the same.
Mastery looks like: They compare two groups up to 10 and correctly say which has more, fewer, or if they are equal.
Common stumbles: Guessing by how spread out a pile looks instead of counting or matching; thinking a spread-out group always has more.
