Standards Covered
- OGM.6.NF.5Open Global Math Standards 2026™ · Math · Level 6 / Grade 5 (Age 10) · Grade 5Interpret multiplication as scaling (resizing), explaining without computing why multiplying by a fraction greater than 1 increases the quantity and multiplying by a fraction less than 1 decreases the quantity.
- OGM.6.NF.6Open Global Math Standards 2026™ · Math · Level 6 / Grade 5 (Age 10) · Grade 5Divide unit fractions by non-zero whole numbers and divide whole numbers by unit fractions using visual models, equations, and story contexts, and solve corresponding real-world problems.
