Class 10 Maths · One-Day Revision

One-Day Revision for Real Numbers

A one-day Real Numbers revision should not become a rushed rereading of the chapter. The goal is to rebuild the scoring spine: Euclid's algorithm, prime factorisation, HCF-LCM relation, decimal expansion rules, and irrationality proofs.

What to finish before the day ends

Can the student solve HCF questions using both Euclid's algorithm and prime factorisation?
Can they reduce a fraction and decide whether the decimal expansion terminates?
Can they write the HCF-LCM product relation correctly and use it only where it applies?
Can they produce one clean contradiction proof for irrationality without copying a memorised paragraph?

One-day revision traps to avoid

Revising only solved examples

Solved examples feel comfortable because the method is already chosen. The exam asks students to identify the method from the question.

How to repair it with Eduro

Mix questions by concept and ask Eduro to make the student name the method before solving.

Skipping proof writing

Many students revise only numerical questions and then lose marks in irrationality proofs because the format is not fluent.

How to repair it with Eduro

Spend 20 minutes writing two full proofs with assumptions, lowest-term form, contradiction, and final statement.

Checking decimal expansion before simplification

A fraction may look non-terminating until it is reduced. The denominator test works only in lowest terms.

How to repair it with Eduro

Make 'reduce first' the first written step in every decimal expansion question.

A sharp one-day Eduro plan

"First 25 minutes: Euclid's algorithm and HCF-LCM relation with mixed numbers."
"Next 25 minutes: decimal expansion questions where every fraction must be simplified first."
"Next 30 minutes: two irrationality proofs written completely, then corrected line by line."
"Final 20 minutes: one mixed test where Eduro asks why each method was chosen."

Parent note

A good Real Numbers revision session should end with the child explaining methods aloud. If they only say 'I know this', ask Eduro to test them with one unfamiliar mixed question.
