Open Learning Lab turns Grade 2 math into an adventure game for young learners ages 6-9. Instead of dressing up worksheets as games, we use 20 genuine action mini-games to teach every concept. The adaptive engine adjusts difficulty in real time and brings mastered skills back for review at 2, 7, and 21 days — real spaced repetition, not a points streak. ADVENTURE MAP Progress through 5 themed chapters: Place Value & Number Sense, Addition & Subtraction, Multiplication Foundations, Measurement & Data, and Geometry & Fractions. Each chapter unlocks after mastering its prerequisites. 20 ACTION MINI-GAMES • Coin Dash Addition — grab the right coins before time runs out • Place Value Builder — stack hundreds, tens and ones to build target numbers • Number Line Skate — land on the right spot to build number sense • Word Problem Adventure — read math stories and pick the right operation • Fact Family Tree — grow related addition and subtraction sentences • Piggy Bank Quest — count coins to hit savings goals • Array Garden — plant arrays to discover multiplication patterns • Times Table Hero — master 1×1 to 10×10 with timed streaks • Partition Puzzle — break numbers apart for flexible thinking • Time Keeper Race — set analog and digital clocks against the buzzer • Money Shopkeeper — count coins and bills to complete transactions • Length Adventure — measure and compare lengths in standard units • Graph Detective — read bar graphs and picture graphs • Volume Voyage — explore capacity and liquid measurement • Weight Wizard — solve balance puzzles by comparing weights • Odd Squad Sorter — sort numbers as odd or even • Rounding Rocket — round to the nearest ten or hundred • Shape Builder House — identify, build and sort 2D and 3D shapes • Fraction Finder — match fractions on visual models • Tile Garden — cover shapes with unit tiles to explore area ADAPTIVE INTELLIGENCE The engine tracks every answer, advances difficulty when ready, drops a level after 3 consecutive misses, and revisits mastered skills at 2, 7, and 21 days. 22 SKILLS ACROSS 5 CHAPTERS Covers the full Grade 2 Common Core curriculum (CCSSM) with extensions into Grade 3: place value, fluency within 20, addition and subtraction within 100 and 1,000, time and money, measurement and data, geometry and fractions. PET COMPANIONS & REWARDS Choose from 8 collectible pets (Kitty, Puppy, Bunny, Bear, Fox, Panda, Unicorn, Dragon). Earn coins and gems from correct answers and spend them on hats, outfits, wallpapers and furniture. Every reward is earned through learning — never purchased.

Make math part of play with Numberton. Explore counting, addition, subtraction, multiplication, division, fractions, decimals, shapes and more, from preschool through Grade 5. Telugu and Tamil learners can match 100 everyday words and 100 mathematical terms with English in separate Kindergarten activities. Bilingual word books support review, and Little Explorers includes guided native-letter tracing. Sail through Island Quest for Grades 4–5: load your boat, steer through the sea, grow a garden and restore the lighthouse. Get Numberton Festival ready in Grades 1–3: pack fruit, connect roads, share a picnic and finish the flags. Both adventures have four connected scenes and saved progress for each child and grade. At sea, use the captain’s number clue to choose matching buoys among decoys. Grade 4 practises repeated addition; Grade 5 introduces multiples of 7, 8, 9 and 11 with different gaps and ascending or descending patterns. Watch worked examples, try hands-on activities and practise through games. Meet friendly dinosaurs in Dino-Math Party, catch answers in Math Fishing and balance both sides in Equal Crossing. Younger children can explore counting, shapes, patterns and tracing in Little Explorers. Fraction addition and subtraction include a hint that shows both bottom numbers’ multiples and highlights their first shared number. Change either bottom number to explore a new example. Other adventures include Numberton Safari for whole-number and decimal rounding, Circuit Cruisers for geometry, and Fraction Forge for hands-on fraction puzzles. Challenges adapt to the selected grade. Families can create local player profiles, follow progress, choose a grade and make printable worksheets. The redesigned iPad home puts learning activities, featured games and topics within easy reach in portrait or landscape. Choose from 14 app languages: English, Spanish, Brazilian Portuguese, French, Telugu, Tamil, Hindi, Arabic, Malayalam, Bengali, Kannada, Russian, Japanese or Simplified Chinese.

English recorded lesson narration is included with the app. On iOS 26 and later, families can choose optional compressed Spanish, Telugu, Hindi, Tamil or French recordings for the selected grade.

Recording availability depends on the language, grade and supported iOS version. Kindergarten home cards use a consistent layout that adjusts to larger text. Math Buddy is optional and requires grown-up setup. Supported on-device AI options run locally on compatible devices; some require an initial model download. Online AI options require internet access and a provider configured by a grown-up. Core learning does not require AI. Support: https://numberton.app Privacy: https://numberton.app/privacy.html
