How to play
A bunch of balloons floats up the screen, each labelled with a subtraction problem. Tap the balloon whose answer matches the target shown at the top to pop it with a satisfying confetti burst. Wrong taps don't punish — the balloon simply drifts away — but they don't score either. Subtractions start within ten and grow to twenty across a five-minute session, with a streak meter that keeps the difficulty climbing as the child gets comfortable.
What your child will learn
- Build subtraction fluency
- Understand take-away concepts
- Recognize subtraction as inverse of addition
Skills practiced
- Number sense
- Mental math
- Problem solving
Why this age range
Built for grades 1–2 because subtraction within twenty (especially across the ten boundary, like 13 − 7) is one of the trickier skills of early elementary. Children at this age usually move from take-away thinking ("I had 13, gave away 7") toward counting-up ("7 to 13 is 6"). The game leaves room for both strategies.

Notes for parents
Watch how your child approaches each balloon. A child who's just memorised the answers will pop quickly; a child who genuinely understands subtraction will sometimes pause on a tricky one (like 13 − 5) and you'll see them counting backwards. Both are fine. The pause is the math happening — let it happen. Resist correcting before they answer; the wrong answers are how the right strategies eventually settle in.
