A Game to Teach Kids Addition and Subtraction (Free, with Dots)

See numbers as groups, not one-by-one

Fast calculators don’t count "●●●●●" one dot at a time — they see "a group of five" at a glance. This ability to know a quantity without counting (number sense, or subitizing) largely determines the speed and accuracy of addition and subtraction.

That’s why showing dots alongside the numbers helps at first. Present "5 and 3" as clusters of dots and kids can see them combine into 8, or see that taking 3 from 8 leaves 5. Learning the make-up of numbers as pictures (5 is 2 and 3; 10 is 6 and 4…) is the groundwork for later mental math.

• Pair numerals with dots to grasp "number groups"
• Learn composition/decomposition as pictures (5 = 2 and 3, 10 = 6 and 4)
• Thinking in tens makes carrying much easier
• Value how they thought about it, not just the answer

Why hear the problem and pick from three

When kids have to read the equation, they can be so busy decoding digits and symbols that little attention is left for the actual math. Reading the problem aloud removes that reading load so they can put their energy into thinking. Hear it, check with dots, tap to choose — the more senses involved, the better it sticks.

Answering by three choices, rather than free typing, is deliberate too. Kids don’t get stuck on a keypad and can focus on "which one is it?" The ease of an instant retry after a miss keeps the "one more!" spirit alive.

How to play (Kids Math)

The free tool Kids Math reads a single-digit addition or subtraction problem aloud and you answer from three choices. It all runs on the device and no records are sent anywhere (speech uses your device’s built-in voice; the correct-answer chime is synthesized on the fly).

The steps:

• Open Kids Math and choose a difficulty (Addition only / Up to 10 / Carrying and borrowing)
• Listen to the read-aloud problem (tap the 🔊 button to hear it again)
• Check the number groups with the on-screen dots
• Pick your answer from the three choices
• 10 questions per round; your best per difficulty is saved on the device for repeat tries

From finger-counting to mental math — how to keep going

Counting on fingers is fine at first — it’s a natural way to link numbers to quantity. But counting from 1 every time is slow, so use the dots to highlight groups of five and ten, and gradually shift to counting on ("after 5 comes 6, 7") instead of starting over.

Move up difficulties one step at a time. Build confidence with "Addition only," widen the range with "Up to 10," then reach "Carrying and borrowing." For 9 + 4, look at the dots together and make a ten: "9 needs 1 to make 10, and 3 left over makes 13." Praise sound thinking over speed.
