About this generator

This page collects everything pupils aged 12–14 (grades 6–8) typically practise: negative numbers, expressions, equations, scale, circles and probability. The default sheet mixes all six areas — numbers, fractions, percent, algebra, geometry and statistics — at a level suited to the age group, so it works well as a weekly review, a diagnostic before a new unit or homework. Switch to a single area to focus on one skill. The answer key is calculated by the website and includes units for every word problem. No sign-up and no personal data.

Plan a useful printable

Start with one clear learning goal and choose only the settings that support it. A short, focused sheet is often easier to explain, complete and review than a crowded page. The live preview makes it possible to check spacing, task count and difficulty before paper is used. Create another version when a class needs the same skill with different content.

Adapt it to the learner

Use fewer items, larger writing areas and familiar content for beginners. Increase the amount, range or complexity gradually for confident learners. Teachers can also combine the printable with oral instructions, pair work or a short follow-up discussion. Because every page is customizable, the same activity can support a warm-up, independent practice, homework or revision.

Print clearly and reuse

Choose A4 or US Letter to match the printer, then print at 100 percent whenever exact spacing matters. The PDF option uses the browser print dialog and creates a clean file for later use. Generated content is prepared in the browser, requires no pupil account and has no watermark. Review every sheet before sharing it, especially when you add your own words or text.
