Numbers

Numbers is an engaging and educational Chrome extension designed to help preschool and primary school children improve their numerical skills through an exciting game format.

The game's objective is to teach the composition of numbers by representing them as the sum of two addends. Players solve puzzles featuring three shapes: two bottom shapes with numbers (one possibly missing) and a top shape showing their sum. Kids select the missing addend, fostering practical arithmetic skills.

With three difficulty levels — Easy (sums up to 10), Medium (up to 20), and Hard (up to 100) — the extension supports progressive learning. It includes a training mode for skill-building and is completely free, requiring no registration or internet access.

Ideal for young learners, Numbers makes math fun and accessible while encouraging mental calculation and numerical understanding.
