MathDrillFourthGrade vs Numina

This is a math drill for fourth graders with multiple reward animations for correct answers. The problem types are addition, subtraction, multiplication, division, decimals, fractions, coordinate grids, factoring, line graphs, order of operations, Venn diagrams, cube volume, word problems, statistics, and simple algebra. A worksheet page can be accessed when the problems are too difficult to solve in the child's head. The child can view the number of correct answers, shown with an emoji for each one. There is a simple math game that can be played after every 10 correct answers. If the child enters an incorrect answer, a hint image appears. There is no sound. On a settings page (for adults but with no restrictions) children may be added by name and assigned a level 1 - 3. The name, level and the number of correct answers are stored on your device for future sessions. The app is free, and there are no ads. No Wi-Fi or cell signal is required. The developer does not collect any data from this app.

Numina turns daily math practice into an adventure your child actually looks forward to, and it is built, from the very first tap, on the science of how children really learn. WHY NUMINA IS DIFFERENT Most math apps just drill. Numina teaches. Every new idea begins with a short, friendly concept moment before your child answers a single question, because understanding should come first. From there, an adaptive engine quietly tailors every question to your child's level, so they are always challenged but rarely frustrated. BUILT ON REAL LEARNING SCIENCE Numina is designed around principles that decades of education research support: • The number line: children build genuine "number sense" by placing and comparing magnitudes, not just memorising facts. • Teach, then practise: concepts are explained before they are tested. • Interleaving: skills are mixed rather than blocked, which builds flexible, lasting recall. • Spaced retrieval: Numina brings each skill back for review right as it is about to be forgotten. • Adaptive difficulty: the level adjusts continuously to keep every child in their "just-right" zone. • Misconception-aware: when a child slips, Numina spots the pattern and responds with the right nudge. ONE JOURNEY, SIX MATH WORLDS (AGES 8-11) Numina covers the heart of primary-school arithmetic, about grades 3 to 6: • Sparkfield: number sense & first sums • The Tens Foundry: place value & bigger numbers • Array Grove: times tables, multiplication & division • Fraction Peaks: fractions, equivalence & unlike denominators • Decimal Caverns: decimals & comparing • Ratio Reach: integers & percentages MADE TO BE LOVED, NOT ADDICTIVE A children's app should earn trust: • No ads. Ever. • No third-party tracking and no analytics. • No loot boxes, no pay-to-win, no pressure to spend. • Encouraging, mistake-friendly feedback, never punishing. • Private by design, and built to comply with children's-privacy laws like COPPA. THOUGHTFUL EXTRAS • Daily Spark: one fresh, bite-sized challenge to build a gentle daily habit. • A Collection of glowing "spark" friends to discover and grow. • Hand-crafted medals that celebrate real mastery, not just taps. • Daily missions tuned to your child's progress. • A Home-Screen widget, plus iCloud sync across iPhone and iPad. • Optional on-device intelligence adds fresh word-problem variety, processed privately on the device, and easy to switch off. • Works fully offline. FOR GROWN-UPS A parent area (behind a simple gate) lets you see exactly what your child is mastering, set their starting point, and manage settings. No account, no sign-up, no data harvesting. Just clear progress. Numina is for curious kids aged 8 to 11, and for the grown-ups who want screen time to genuinely count.
