Divide 3-Digit Numbers with Number Bonds 4-48

Transition from area models to number bonds. Divide by breaking the total into smaller, known multiples that are easier to divide. What's 278÷2? Think of 278 as 200+60+18, or 2 hundreds, 6 tens, and 18 ones. 278÷2 = (200÷2) + (60÷2) + (18÷2) = 100+30+9 = 139. Find and add partial quotients to get the total quotient.
