What is the free Divisibility Rules Quiz?

The Divisibility Rules Quiz is a free web app for practicing multiples and divisibility rules in a 4-choice quiz format.

The questions are original, automatically generated, and designed for upper elementary students through junior high school learners.

Practice rules from basics to challenge level

The app covers divisibility by 2, 3, 4, 5, 6, 8, 9, 10, 11, 12, 15, 18, 25, and 100.

Students can practice last-digit rules, digit-sum rules, last-two-digit and last-three-digit rules, combined rules, missing-digit questions, and short original word settings.

Dynamic hints with diagrams

Hints change according to the current question. They show digit sums, highlighted final digits, combined-rule checks, and the 11-rule alternating sum with simple original SVG diagrams.

My Page stores challenge history, best records, and often missed questions, so repeated practice is easy.

Build number sense step by step

Divisibility rules are useful when students simplify fractions, look for factors, check common multiples, and handle integer problems. This quiz helps learners notice patterns such as last digits, digit sums, and combined conditions instead of relying only on long division.

Each question is short, so it works well for a few minutes of daily review. The faster students recognize the rule, the more confidently they can move through later arithmetic and algebra topics.

For students, teachers, and families

Students can use the app for quick self-study, teachers can use it as a warm-up activity, and families can use it for light review at home. The ranking and My Page features make practice feel like a small challenge, while the hints keep the focus on understanding.

The goal is not just to memorize a list. The quiz encourages students to ask, “Which part of the number should I look at?” and “Why does this rule work here?”
