How to use the tool

  1. Pick a difficulty: easy, medium or hard.
  2. Choose how many problems you want (10, 20 or 30).
  3. Print or save as PDF. “Create new version” gives brand-new problems with the same settings.

About this generator

Second grade is where students add and subtract fluently within 100 and start regrouping. The easy level avoids regrouping, medium mixes it in and hard uses it on most problems, so you can differentiate one lesson three ways. Every sheet has a separate answer key calculated by the website, so answers always match the problems. Free, no sign-up, US Letter by default.

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.
