Chapter 4 Divide by One Digit Numbers

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)
