Finding the Unknown in a Division Equation Authentic Assessment #5 Scoring Rubric – 3.OA.4: Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = _ ÷ 3, 6 × 6 = ? Mathematical Practice: 1 and 2 SOLUTION: This solution shows that 12 split into groups of 6 will result in 2 groups. This solution shows that 12 split into 6 equal groups will result in 2 in each group.
