Explain your thinking and spot errors in someone else's worked example.
These questions have no single number to type. The child is shown a claim or a worked answer and asked whether it is right and why. Because they are self-assessed, they are the closest thing here to how a teacher would actually probe understanding.
Examples of what the practice generator produces. Answers are shown so parents and teachers can judge the level before starting.
1. Meera says 1/3 is bigger than 1/2 because 3 is bigger than 2. Is she right? Explain your thinking.
MediumAnswer: No - the more parts a whole is cut into, the smaller each part is, so 1/3 is less than 1/2
2. Is 6 x 8 the same as 8 x 6? Explain why.
MediumAnswer: Yes - multiplication can be done in either order, and both give 48
3. Arun works out 400 - 176 and gets 336. Without doing the full sum, explain how you can tell he is wrong.
HardAnswer: 400 - 176 must be less than 400 - 100 = 300, so 336 is too big. The correct answer is 224
Questions are generated fresh each time, so they never run out.
Printable worksheets
Generate a explain & reason worksheet of 5–20 questions with a separate teacher answer key, ready to print for a class or for homework.
Three difficulty levels
Easy, Medium and Hard run side by side, so a mixed-ability class can work on the same topic at the level that suits each child.
Instant feedback
Children get up to three attempts with step-by-step working revealed afterwards — no marking needed for practice sessions.
Nothing to set up
No accounts, no logins, no data collected from children. Open the page on any school device and start.
StudyZone is a fun practice tool, not an assessment platform.
Questions are randomly generated and are not a substitute for formal evaluation. A child's performance here does not reflect their academic ability or school readiness.
