What is the unofficial Sansu Kentei Level 10 Quiz?

This is an unofficial free web app for practicing arithmetic skills in a 4-choice quiz format.

The questions, choices, hints, explanations, and diagrams are original. They are not copied from official tests, official samples, textbooks, workbooks, mock exams, or other published materials.

Original practice for early elementary arithmetic

The quiz uses independently created problems based on common arithmetic facts and skills such as place value, addition, subtraction, multiplication facts, time, length, capacity, shapes, tables, graphs, and short word problems.

It is designed for daily review, home study, and warm-up practice before checking official exam information.

How children can use this quiz

This app is designed for quick arithmetic review. Children can answer one course in a short time, check hints when they get stuck, and return to missed questions on My Page.

Because every question is original, the quiz is useful as warm-up practice before using official information or purchased materials.

Skills practiced in Level 10-style review

The quiz helps students connect calculation with meaning: place value, carrying and borrowing, multiplication as equal groups, reading clocks, comparing units, recognizing shapes, and using tables or bar-style data.

Short word problems are included so learners can practice deciding whether to add, subtract, or multiply, instead of only memorizing answers.

For families and teachers

The 4-choice format makes it easy to use at home, in a classroom warm-up, or as a short homework review. Hints are written to show the first step, not just the answer.
