算数・計算ドリル

Easy Math Drills for Elementary School Students

"Arithmetic & Calculation Drills" is an app that allows elementary school students (grades 1-6) to practice addition, subtraction, multiplication, and division a little bit each day. The range and order of problems are based on the Ministry of Education, Culture, Sports, Science and Technology's curriculum guidelines, allowing students to develop their calculation skills at their own pace, matching the school curriculum.

No ads, no tracking, and completely offline. Designed with your child's safety as the top priority.

■ Problems are automatically generated = Challenge yourself with new problems as many times as you like

The app automatically generates problems. Instead of repeating the same problems, new problems are presented each time you work through them, so you'll never run out of questions. Practice thoroughly until you've mastered calculation skills.

■ Three modes for fun and continuous learning

● Practice (Curriculum)

Clear the units for each grade level in order. The "Mastery Gate" system ensures you thoroughly understand the previous unit before moving on to the next. Previously learned units are reviewed after a few days to reinforce their learning and prevent forgetting.

● Time Trial
Challenge how many problems can be solved in 60 seconds. Ideal for speed practice for children who have mastered the basics.

● 100-Square Calculation
Repeated single-digit addition and multiplication to improve calculation speed and accuracy. Challenge yourself to achieve a personal best by timing yourself.

■ Features to Improve Calculation Skills

● Correct range, order, and difficulty level, compliant with the Ministry of Education, Culture, Sports, Science and Technology's curriculum guidelines.
● Supports decimals and fractions (grades 3 and up).
● It's Okay to Make Mistakes. A gentle tone encourages "Let's try again," respecting the child's feelings.

■ Appropriate Characters for Each Grade Level

The app automatically converts kanji characters not yet learned in the child's grade into hiragana. Therefore, even young children who don't know many kanji can read and progress on their own. As long as they can read hiragana, even preschoolers (ages 3-6) can start. As they progress through the grades, they will be able to read using the kanji they have learned.
