Ten Frames — math with smiles Educational math app for children aged 4–7, built around the Ten Frames method. Short, cheerful sessions a child can play independently — no reading required. About the method: Ten Frames is a foundational visual learning tool — a simple frame of 10 cells used to teach early number sense. The method itself is included in mathematics curricula around the world. Children learn to instantly recognize quantities through visual grouping: a filled row is always 5, a full frame is always 10. These benchmarks become anchors for all future mental math. The result: stronger number sense, faster mental arithmetic, less math anxiety. What it covers: • Counting to 10 • Addition and subtraction within 10 • Pairs that make 10 • Doubles • Fair sharing • Visual memory • 9 Adventure worlds, 82 levels Made for little learners: • A level is 5 problems and runs 2–4 minutes — a full session fits before dinner • Voice narration in English, Romanian and German, so children who cannot read yet play on their own • 10 visual themes children choose themselves (Space, Ocean, Forest, Farm, Candy, Unicorn, Pixel, Slime, K-Pop, Monsters) • 36 stickers and 14 achievements keep effort rewarded, never punished — a wrong answer costs nothing • A parent dashboard to follow stars, streaks and progress Made for parents: • No accounts and no sign-up — hand your child the iPad and they start • Nothing leaves the device. Progress is stored locally, and the app works fully offline • No analytics, no ads, no tracking, no links out of the app • Free to start: counting play is free forever, with free daily problems in every practice mode • One single purchase unlocks everything — every world, mode and theme. No subscription, ever Available in English, Romanian and German.

nonna is a calm math game for young children, where every number is a cat. Combine cats to make the target and clear your pile before the board fills. The free game is all of addition, from bonds to 5 up to 100: dots, ten-frames and numerals, a way to add by passing numbers from one cat to another, and a garden where every cat your child adopts comes to live. Five more worlds, each with its own way of playing: - Multiplication World: drag out a rectangle of cats and watch 3 × 4 become 12. - Subtraction World: sweep cats away and see what is left. - Division World: deal the cats out fairly until none are left. - Fractions World: cut a cushion into equal pieces and find that two quarters make a half. - Geometry World: stretch a band from peg to peg and name the shape it makes, from Kindergarten to Grade 5. Every world gives one free round. All Worlds opens them all: $4.99 a month after a free first week. It renews monthly until you cancel, and you can cancel any time in your Apple Account settings. One subscription covers your whole family (Family Sharing). Bought a world before? It stays yours, and every world is open to you with no subscription. - No ads, no accounts, no tracking; nothing leaves the device - Nothing to read before playing: a hand shows how, then lets go - Colouring pages where the colour you choose is the answer to the sum - A grown-ups area behind a parental gate, with sound, a round timer, the geometry grade and the store Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://clearvistaai.github.io/nonna-support/privacy-policy.html
