Curriculum reference — Ontario: Use regrouping/exchanging language without changing calculations; actual sums determine Ontario scope. Two-digit addition within100 supports Ontario Grade2; range must stay within the identified task. England Year2 adds two two-digit numbers. Selected skills only; reference stage is not an overall reading age, complete curriculum coverage, or an automatic recommendation for every learner.
