Multiplication and Division to Three Digits

Multi-digit multiplication in Grade 5 extends to three-digit numbers and two-digit multipliers. 234 x 6 = (200x6) + (30x6) + (4x6) = 1200+180+24 = 1404. Division with remainders introduces a new decision: when the quotient is not a whole number, what does the remainder mean in context? 17 students need to cross a river in canoes that hold 3 people. 17/3 = 5 remainder 2: you need 6 canoes, not 5. The context determines whether to round up or down.
