About Differentiating Polynomials True/False

Differentiating Polynomials True/False gives ambitious upper-secondary learners a first taste of calculus through the power rule for differentiation. Each question presents a polynomial together with a claimed derivative, and the student decides whether the differentiation is correct. The power rule — that the derivative of x to a power is the power times x to one less than that power — is the foundation of differential calculus, an enrichment and early high-school topic across the US, UK, Canada and Australia, and the gateway to gradients, rates of change and optimisation. The true-or-false format is ideal for a first encounter because it asks students to verify a derivative rather than produce one from scratch, which means checking that each term has been differentiated correctly: that the powers and coefficients have been handled properly. Mixing correct derivatives with plausible wrong ones means every claim must be tested carefully, building accuracy and confidence. The polynomials vary each time so the worksheet stays fresh and reusable, and the five levels raise the powers and coefficients. Each page prints cleanly on a standard A4 sheet, and every level downloads with its own answer key marking each statement true or false. There is no advertising and no sign-up.

Common questions

What is the power rule?
The derivative of xⁿ is n·xⁿ⁻¹, the basic rule for differentiating polynomials.
What grade is this for?
Grade 8 to Grade 9 learners aged 13 to 14, as an enrichment topic.
Is an answer key included?
Yes, every level marks each statement true or false.

A hand for grown-ups

Before you start
Find a calm few minutes with no rush. Let your child know it is fine to find some of it tricky — that is what practice is for.
While they work
Sit nearby but let them lead. If they get stuck, ask "what could you try?" rather than giving the answer — the thinking is the point.
Afterwards
Ask them to show you one they found easy and one they found hard. Praise the effort on the hard one, not just the right answers.
Watch out for
Rushing. If answers come too fast and wrong, slow the pace down together rather than pushing for more.
Away from the screen
Look for the same maths in everyday life — counting stairs, sharing snacks, spotting shapes on a walk.
