About this app

Learn math with Stella and animal buddies!
For ages 4 to 12, from Pre-K to grade 6, one app follows Korea's national math curriculum unit by unit.

To the Stars: Math is a learning app where children write answers by hand and work problems out on a scratch pad instead of picking from choices. It covers 79 units and more than 2,000 problem types: counting and shapes for preschoolers, then arithmetic, times tables, fractions, decimals, geometry, measurement, graphs, and word problems. Study one unit in depth, or mix units for review.

■ Built on Korea's national curriculum
Lessons follow the national mathematics curriculum of Korea's Ministry of Education, in the unit order Korean schools use. Grades in the app are Korean school grades, so a topic may come a little earlier or later than in your country. Every problem, hint, and menu is available in English.

■ What each grade covers
· Preschool (ages 4–7): counting, comparing, patterns, shapes, sorting, making ten, first addition and subtraction
· Grades 1–2: numbers to 10,000, addition and subtraction with regrouping, times tables, length, time, tables and graphs
· Grades 3–4: multiplication and division, fractions and decimals, circles, angles, polygons, capacity and weight, bar and line graphs
· Grades 5–6: factors and multiples, operations with fractions and decimals, area and volume, ratios and proportions, averages and chance
· Times Tables: focused practice on the 2 to 9 tables

■ Handwritten answers and a scratch pad
Answers are written with a finger or a pen. The app reads each digit and lets your child fix it right away. The scratch pad beside each problem is for column sums and carrying marks, just like paper. On tablets, the problem and scratch pad sit side by side like an open notebook.

■ Basic, advanced, and olympiad problems
Each unit starts with basic problems and moves on to advanced ones. Grades 1–6 also include olympiad-style problems. Numbers and stories change every time, so problems do not repeat.

■ Concepts you can see and touch
Move stars to make 10, split fraction bars, measure angles, and draw picture graphs. The Help button gives up to three step-by-step hints instead of the answer.

■ Today's Lesson and a mistake notebook
Today's Lesson picks the day's work from progress, weak spots, and review. Missed problems return a few days later as recall problems, and the learning record shows which types are missed most.

■ Animal buddies that grow with Stella
Food earned by studying feeds an animal buddy and decorates its room. Sixteen buddies each have their own story, and 25 mini-games offer a break. At the end of the day, the buddies your child studied with come out to say goodbye.

■ Growth records for parents
See days studied, time, problems solved, and accuracy by day, week, and month. Set a daily goal and a screen-time limit, and share a learning report at parent–teacher meetings.

■ No ads, and no purchases on the child's screen
The app shows no ads. The child's screens never show payment prompts; plans and settings live only in the parent area. With a guardian's consent the app can be used without an account, and linking an account carries progress across devices.

Two new lessons a day are included in every grade, and reviewing missed problems does not count against that. The paid plan adds unlimited new lessons, advanced and olympiad problems, extra family profiles, and printable worksheets. Prices are shown in the Google Play purchase screen, and subscriptions can be cancelled anytime in Google Play.

Core lessons work offline. Sign-in, sync, online read-aloud, and plan checks need an internet connection.
