Standards Covered
- OGM.4.OA.1Open Global Math Standards 2026™ · Math · Level 4 / Grade 3 (Age 8) · Grade 3Interpret products of whole numbers as total objects in equal groups, arrays, jumps on a number line, repeated addition, and multiplicative comparisons (e.g., interpret 3 × 24 as 3 times as much as 24).
- OGM.4.OA.6Open Global Math Standards 2026™ · Math · Level 4 / Grade 3 (Age 8) · Grade 3Solve and formulate one-step and two-step contextual word problems involving the four operations (+, -, ×, ÷), additive structures (composition, transformation, comparison), multiplicative scaling, and correspondence (n to m objects); represent situations using strip diagrams, arrays, and equations.
- OGM.4.OA.2Open Global Math Standards 2026™ · Math · Level 4 / Grade 3 (Age 8) · Grade 3Interpret whole-number quotients as fair sharing (equal shares partition) and equal grouping (measurement partition); represent quotients using concrete manipulatives, diagrams, and number sentences.
- OGM.4.OA.5Open Global Math Standards 2026™ · Math · Level 4 / Grade 3 (Age 8) · Grade 3Determine the unknown whole number in addition, subtraction, multiplication, or division equations relating three or more numbers, representing unknowns using symbols, boxes, or letter variables.
