Show the Operation — Add & Subtract on a Ten Frame
Represent addition and subtraction on a ten-frame with counters. For "3 + 2", place 3 counters then 2 more in a second colour to see the two parts make 5; for "5 − 2", start with 5 and take 2 away. Aligned to Common Core K.OA.A.1 — represent addition and subtraction with objects, fingers, and drawings.

About this activity
For "3 + 2" the child places 3 counters and then 2 more in a second color so the two parts are easy to see; for "5 − 2" they start with 5 and tap to take 2 away. Showing the operation on the ten-frame — not typing a number — is the work. It's a free, interactive Kindergarten math activity that plays in the browser with no sign-up.
The big idea is that addition and subtraction are actions you can show, not just answers you write. The second counter color makes the two addends visible as separate groups, and removing counters makes "take away" literal. The child is modeling the operation rather than typing a number, so the meaning of putting together and taking apart comes before the arithmetic.
It is aligned to Common Core K.OA.A.1 — representing addition and subtraction with objects, fingers, drawings, and other tools. No timer, no score — just calm, playful practice.
What's inside this activity
- Designed for Grade K learners (ages about 5–6)
- Common Core strand: Operations & Algebraic Thinking
- Aligned to Common Core standard K.OA.A.1
How to play
Read the problem, like 3 + 2 or 5 − 2.
Place or remove counters on the ten-frame so it shows the operation, then press Check.
Not quite? Adjust the counters and try again — there is no timer and no score.
What your child practices
- Showing addition by placing two groups of counters in two colors
- Showing subtraction by taking counters away from a starting group
- Seeing the two parts that make a whole on the frame
- Modeling what an addition or subtraction sentence really means
Learning goals
Represent addition and subtraction with counters — the focus of Common Core K.OA.A.1
Understand addition as putting together and subtraction as taking apart
Build the modeling habit that word problems and number sentences depend on
