What each level generates

Grade 2 adding in your head — the exact skill behind each difficulty setting, straight from the generator.

  1. Level 1Sums with no carrying
  2. Level 2Sums that carry
  3. Level 3Add three numbers

Grade levels follow the progression common to most English-language curricula — not one specific national curriculum. Every level shows exactly what it generates, so you can check the fit with your own program. See the full scope & sequence →

Frequently asked questions

▸What should a Grade 2 child know in mental maths?

Adding and subtracting within 100 in their head: two-digit plus one-digit across a ten, two-digit plus two-digit with a carry, and subtraction that needs an exchange. These sheets generate all three across their seven skills, plus three- and four-number chains on the Mixed Chains sheet.

▸What does "bridging ten" mean?

It means crossing a multiple of ten during the calculation, as in 38 + 7 or 43 − 8. It is harder than 32 + 5 because the tens digit changes, so the second level of Adding in Your Head and of Taking Away in Your Head is built to bridge every time rather than avoid it.

▸How many questions should a Grade 2 sheet have?

Twenty to thirty is a good session. Use the stepper to size it, and press Shuffle for a completely fresh set at the same skill and level tomorrow — the difficulty stays identical, so daily progress is easy to compare.

▸How do the levels differ at Grade 2?

The level changes how hard one skill is, not which skill you get. On Adding in Your Head, level 1 pairs two two-digit numbers with no carrying, level 2 makes the ones column carry every time, and level 3 adds three numbers. Everything stays within 100, and Mixed Chains is the skill that strings numbers together, such as 52 + 18 − 34.
