Math Basics vs さんすうのべんきょう

MAKE MATH PRACTICE A FUN DAILY HABIT FOR CHILDREN AGED 5 TO 12 From simple sums to full written methods, children can practice addition, subtraction, multiplication, and division step by step, explore fractions visually, and learn about factors, primes and geometry too. PRIVACY FIRST No ads. No tracking. No accounts. No internet required. All data stays on your device. START SIMPLE AND BUILD CONFIDENCE Practice everything from basic calculations to long addition, long subtraction, long multiplication, and long division. A step by step grid view shows carries, borrows, and partial products so children can understand the method, not just the answer. FACTORS, PRIMES AND MULTIPLES Learn the divisibility rules from 2 to 13, find the prime factors of a number, build numbers from prime tiles, and split them with factor trees and factor ladders. Then work out the greatest common factor and least common multiple of two numbers, with step-by-step help for the final multiplication. When an answer is wrong, the explanation uses the very number the child was working on. SHAPES, SOLIDS AND ANGLES Name flat shapes and solids, tell regular polygons from irregular ones, count sides, corners, faces and edges, and recognize acute, right and obtuse angles. A wrong answer is explained, not just marked: the parts are counted one at a time, a solid comes apart on screen to show the faces hidden at the back, and an incorrectly identified angle is compared with a right angle. UNDERSTAND FRACTIONS Introduce fractions in a hands on, visual way. Children shade parts of a whole and compare fractions side by side, building a real understanding of what fractions mean. TIMES TABLES AND FLASHCARDS Practice multiplication and division facts from 2 to 10. Flip card flashcards help children review what they know and focus on what still needs work. A color coded mastery view makes progress easy to see. DAILY GOALS AND STREAKS Set goals based on questions answered, correct answers, accuracy, or practice time. Progress bars and streaks encourage children to keep practicing every day. PARENT DASHBOARD A PIN protected parent area helps you follow each child’s progress. View accuracy, time spent, strengths, weaknesses, and streaks, then export PDF or CSV reports. DESIGNED FOR FAMILIES Choose from four visual themes. Parents can assign different themes to each child. Family Sharing is supported, so one purchase can be used by the whole family. TRY IT FREE FOR 7 DAYS, THEN KEEP PRACTICING EVERY DAY Unlock everything with a single one time purchase. No subscriptions. When the trial ends, every child still gets 15 minutes of free practice a day.
