Short answer. K.CC.C.6 means comparing two groups to say which has more, fewer, or the same, using matching and counting. Snack-time games make this one easy to practice.
Quick answer
Show your child two groups of things, say 6 crackers on your plate and 4 on theirs, and they should be able to tell you which group has more, which has fewer, or whether the groups are equal. Kindergarteners get there two ways: matching items up one to one and seeing which group has leftovers, or counting both groups and comparing the counts. Both strategies count as meeting the standard.
Why parents see this skill
Comparing quantities is where number sense starts becoming judgment, the sense of 8 being more than 5 rather than just coming later in the song. It leads straight into comparing written numerals, then into greater-than and less-than work in first grade, and eventually into understanding what subtraction actually finds out.
For reference
Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies.Official Common Core source
See it, then try it
You do not need a lesson plan. Look for these signs in ordinary play, reading, and conversation, then choose one short activity.
Deal out snacks or toy cars into two piles, sometimes fair, sometimes deliberately lopsided, and appoint your child the inspector who must rule: more, fewer, or equal? Ask how they know. If they only eyeball it, nudge them to prove it by matching or counting. Kids adore catching a parent being unfair.
Grab a handful of socks from the laundry for each of you. Pair them up across the two piles, one of yours next to one of theirs, and see whose pile runs out first. The leftovers make "more" visible without any counting. Then count both piles to confirm. Laundry gets sorted either way, so nobody loses.
Each of you grabs a fistful of dry pasta or cereal and drops it on the table. Guess first who grabbed more, then check by lining the pieces up in two rows or counting. Best of 5 rounds. The guess-then-verify rhythm builds estimation on top of the comparing skill, for free.

Open resourceHow is “more” different from “greater than”?
More is the everyday word children usually learn first. Greater than is the math phrase they will see later with numbers and symbols. In kindergarten, it is fine to use both gently, as in “7 is more than 5, so 7 is greater than 5.”
What helps when my child mixes up more and less?
Use real objects and keep the groups small. Matching one object from each group is often clearer than counting alone. If one group has leftovers after matching, that group has more, and the other group has less.
Are “equal” and “same” the same thing?
They can mean the same amount, but children may hear “same” and think the objects must look identical. Try saying “equal means the same number.” Two groups can be equal even if one has red blocks and the other has blue blocks.
How does comparing quantities connect to addition?
Addition changes the size of a group, so comparing helps children notice what changed. If one group has 3 and you add 2 more, your child can see that the group is now larger. This builds a gentle bridge from counting objects to early addition thinking.
Which Whizki worksheets cover K.CC.C.6?
Start with kindergarten counting and number sense pages that ask children to count groups and compare amounts. Addition and subtraction pages can also help once your child is ready to see how adding or taking away changes a group. Choose pages with clear objects and small numbers first.
