Chapter 4: Divide by 1-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)

Chapter 4 Standards: Operations and Algebraic Thinking; Number and Operations in Base Ten

​

Use place value understanding and properties of operations to perform

multi-digit arithmetic;

CC.4.NBT.6 Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays and/or area models.

Use the four operations with whole numbers to solve problems;

CC.4.OA.3 Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
