What is the Grade 9 Square Roots Quiz?
The Grade 9 Square Roots Quiz is an unofficial free web app for practicing square roots and radicals in a fast 4-choice format.
Learners can review the meaning of square roots, the difference between square roots and the principal square root, simplifying radicals, comparing values, multiplication and division, addition and subtraction, rationalizing denominators, equations, and original application problems.
All questions, options, explanations, short scenarios, and diagrams are independently created for this app. They are not copied from textbooks, workbooks, entrance exams, mock exams, proficiency tests, or official PDFs.

Dynamic hints for each question
Hints change according to the current problem. They show the first point to check, the transformation to use, and the final confirmation step.
Original SVG diagrams are used for perfect squares, radical simplification, radical operations, rationalizing denominators, equations, and geometry applications.
Useful for short review
Each question is short, so the app works well for lesson review, quick test preparation, classroom warm-ups, and home study. Missed questions can be reviewed later on My Page.
The quiz is designed as a study support tool, not as a replacement for official curriculum materials or classroom instruction.
Use it for classroom warm-ups and home study
The quiz format is short and simple, so it can be used after a lesson, before a test, or as a quick home study check. Hints show what to look at first and how to confirm the answer.
Students can practice common trouble spots such as forgetting ±, adding inside radicals, simplifying radicals, and rationalizing denominators.
