Frequently asked questions
- Which grade is it for?
- Sums to 10 suit kindergarten and first grade, to 20 first and second grade, to 100 second and third grade.
- Are there negative answers?
- No — subtraction never goes below zero.
- Do all spaces with the same colour have the same sum?
- No — different sums with the same answer share a colour, so each space must really be worked out.
- Can I check the work quickly?
- Yes — the answer page shows the picture coloured in; compare it at a glance.
- Is anything uploaded?
- No. The pictures are made in your browser.
