In this unit, students build on their understanding of multiplication and division from Grade 3. They interpret a multiplication equation as a comparison, e.g., that the equation 35 = 5 x 7 is stating that 35 is 5 times as many as 7 and 7 times as many as 5. They will represent multiplicative comparisons as multiplication equations.
