Short answer. K.OA.A.2 asks kindergarteners to solve add and subtract story problems within 10 using objects or drawings. What it means and how to practice at dinner.
Quick answer
Story problems arrive in kindergarten, sized for kindergarteners: all the numbers stay within 10, and kids are expected to solve them with props, not in their heads. Someone tells your child a tiny story ("You have 6 grapes and eat 2, how many are left?") and they figure it out using objects, fingers, or a quick drawing. The heavy lift is not computation. It is listening to a story and deciding whether things are coming together or going away.
Why parents see this skill
Word problems are where math meets actual life, and they are also where many older kids struggle most. A kindergartener who learns to picture the story before touching numbers builds the habit that carries all the way through elementary school, where the problems get wordier but the approach stays the same.
For reference
Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.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.
Once a meal, tell one story problem starring your actual kid and actual food: "You had 8 peas. You fed 3 to your imaginary dragon. How many are left?" Let them solve it with the real peas. Silly beats sensible here; kids attend better to a dragon than to a generic "Sally." One problem a night is 365 problems a year.
Swap seats: your child makes up a story problem and YOU solve it with blocks, thinking out loud and occasionally making an error for them to catch. Inventing a problem takes more understanding than answering one, and correcting a grown-up is irresistible. Keep the numbers within 10 and keep rounds under two minutes.
During regular play, add math beats to the story line: 4 dinosaurs at the watering hole, 3 more stomp over, how many drinking now? The toys are already out and the play is already happening, so this costs you 30 seconds. Acting the story with figures is precisely the object-based solving the standard describes.

Open resourceDoes my kindergartener really need to solve word problems?
Yes, but they should be small, concrete, and within 10. At this age, a word problem can be as simple as 3 apples on a plate and 2 more added. Your child can use objects or drawings instead of solving it in their head.
My child knows numbers but freezes when the math is in a story. What should I try?
Start by acting out the story with objects. Read one sentence, move the objects, then read the next sentence. This helps your child connect the words to what is changing.
Why do drawings help with kindergarten word problems?
Drawings make the story visible. A child can circle groups, cross out what leaves, or match two groups to compare them. That picture often does the hard thinking before the equation comes.
When should I stop reading the problem aloud?
Keep reading aloud while the reading is getting in the way of the math. Slowly invite your child to read familiar words or numbers with you. The goal is math understanding, not independent reading speed.
