Frequently asked questions

▸What word problems should a Grade 8 student master?

Percent-change problems, steady-rate problems (kilometres, pages or parcels per hour, and words per minute), and simple-interest calculations. The Percent Increase & Decrease, Rates & Speed and Simple Interest sub-skills generate exactly those, with clean whole-number answers.

▸How do these help prepare for algebra?

They reward writing each story as an expression — say, 5000 × 120/100 for a 20% rise, or principal × rate × years for interest — before computing. Getting fluent at turning a situation into a symbolic step is precisely the move Grade 8 algebra formalises, so the practice transfers directly.

▸Are the answers always whole numbers?

Yes. Populations, distances, and interest are all built so the result is an exact whole number — a growing population comes out in whole people, a distance comes out in whole kilometres, and interest is a whole-dollar amount — so answers stay clean while the setup stays demanding.

▸Can I run the same test across a class and again weeks later?

Yes. The shareable link reproduces the identical problems and answer key every time it opens, so a class-wide test and a later re-test compare like for like. Press Shuffle whenever you want a fresh version instead.

▸Do these worksheets cover exponents, equations, or scientific notation?

Not on these sheets — they target percent change, rate, and simple-interest reasoning, the applied backbone of Grade 8. All three are on the site elsewhere, though, so it is worth knowing where. Exponents are covered under other names: Powers of Integers at Grade 8 does squares, cubes and two powers multiplied, Squares at Grade 6 drills the square numbers on their own, and Powers in Expressions at Grades 6 and 7 puts them inside a longer chain. Square and cube roots are on the Grade 8 geometry page. Equations are Pre-Algebra's whole subject. Scientific notation is the one genuinely not here yet.
