In Chapter 4 students will:
Learn how to model division, and use the division algorithm to divide up to 3-digit dividends by 1-digit divisors
Learn different methods to divide, including using models, repeated subtraction, and the standard division algorithm
Learn to divide with remainders
Vocabulary:
compatible numbers - when estimating, using numbers that are easy to compute mentally (ex. to divide 438 / 6, use 420 / 6)
multiple - a number that is the product of a given number and a counting number
partial quotient - a method of dividing in which multiples of the divisor are subtracted from the dividend and then the quotients are added together
remainder - the amount left over when a number cannot be divided equally
dividend - the number that is to be divided in a division problem (the number inside the division box)
divisor - the number that divides the dividend (think of the suffix -or meaning one who does; such as conductor is one who conducts; the divisor is one who divides)
