Frequently asked questions

▸When do kids learn regrouping in addition?

Typically during Grade 2, after two-digit addition without carrying is secure. Work through the Add Without Regrouping page first, then switch to the Add With Regrouping page when no-carry sums are consistently correct — they are two separate skills here, not two stops on one slider.

▸How many two-digit problems make a good Grade 2 sheet?

10–12 is a solid session, or 8 when regrouping is brand new — each problem takes more thinking than a simple fact. Adjust with the question-count stepper.

▸My child keeps forgetting the carried one — what helps?

Shorter sheets, bigger print, and saying the carry out loud. Print at a large size with the easy-read font, and check answers together against the key page immediately so the error never gets rehearsed.

▸Can I share a worksheet with another parent or my class?

Yes — send the link. It reproduces the exact same worksheet, problems in the same order, so everyone works from an identical sheet and one answer key fits all.

▸What paper sizes are supported?

A4 and US Letter. Pick yours in the controls and both the on-screen preview and the downloaded PDF reflow to that exact paper size.
