I give your child a set of problems — not from one chapter, but spanning foundational areas: fractions, ratios, exponents, algebraic identities, factorisation, linear equations. I also include a few problems from their current Class 10 syllabus.
I don't ask them to rush. I tell them to work through each problem the way they normally would, write down what they try, and not worry about whether the answer is right.
While they work, I watch. I notice which problems they go to immediately and which ones make them pause. I look at what they write first — what they instinctively reach for. I notice where they cross out and start again, and what changes when they do.
These small things tell me more about a student's understanding than any report card.
