Number Set: Abacus & Counting

Number Set brings the classroom math kit to your tablet: a 100-bead abacus, counting sticks and counting beans. Children explore numbers by tapping, sliding and bundling. Designed for ages 4–8. Every instruction is spoken aloud, so children who can't read yet can play on their own.

THREE MATERIALS
• Abacus: 10 rows of 5 + 5 colored beads. Slide beads to show numbers, compare rows and make 10.
• Counting sticks: take sticks from the box, count them, sort them by color and tie 10 into a bundle with a rubber band.
• Counting beans: put beans on plates and in a ten frame, finish patterns and feed the hungry caterpillar.

WHAT CHILDREN PRACTICE
• Counting to 100, skip counting by 2s, 5s and 10s, and counting back
• Tens and ones: bundles and two-digit numbers
• Addition and subtraction to 20, making 10
• Comparing: more, fewer, equal
• Patterns, recognizing amounts at a glance and estimating

HOW IT WORKS
Every instruction is voiced in 8 languages (English, Turkish, German, French, Spanish, Portuguese, Italian and Japanese) by a warm, natural narrator. The recordings are built in, so no internet is needed. No timers and no penalties. After a wrong answer, children get encouragement first, then a hint, then "Let's do it together." A counter shows the number as beads or sticks are added. Each material has a free play mode. Stars unlock bead colors and hats for the caterpillar; there is no virtual currency.
