OGM.3.NF.1Open Global Math Standards 2026™ · 2nd GradeUnderstand fractions as equal parts of a whole, region, length, set of objects, or quantity; partition shapes and sets into 2, 3, 4, 5, 6, 8, and 10 equal parts; recognize and write unit and non-unit fractions (1/2, 1/3, 1/4, 2/4, 3/4, 1/5, 1/6, 1/8, 1/10) using numerator and denominator terminology.
OGM.3.NF.2Open Global Math Standards 2026™ · 2nd GradeCompare fractions with like denominators and unit fractions (1/n); explain the inverse relationship between the number of equal parts and the size of each part; establish simple equivalences (e.g., 2/4 = 1/2, whole as 2/2, 3/3, 4/4); add and subtract fractions with common denominators concretely and pictorially.
