Chapter 2 Divide Whole Numbers

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

5.NF.B.3 - Interpret a fraction as division of the numerator by the denominator a/b. Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem.

Chapter Two Vocabulary

compatible numbers - numbers that are easy to compute with mentally
estimate - to finder an answer that is close to the exact amount
inverse operations - opposite operations or operations that undo each other, such as multiplication and division
remainder - the amount left over when a number cannot be divided equally
dividend - a number to be divided by another number
divisor -a number by which another number is to be divided.
factor - a number or quantity that when multiplied with another produces a given number or expression
partial quotients - refers to a method used in solving large division mathematical problems. The method uses simple logic by allowing the student to see the problem in a less abstract form.
product - the answer to a multiplication problem
quotient - the answer to a division problem

Lesson 2.1 - Multiply by Multi-Digit Numbers

Students will multiply by multi-digit numbers.

IXL Practice (click on the links below)

Multiply 2-digit numbers by 2-digit numbers

Multiply 2-digit numbers by 3-digit numbers

Multiply by 2-digit numbers by larger numbers

Multiply by 3-digit numbers

Lesson 2.3 - Investigate: Division with 2-Digit Divisors

Students will model division with 2-digit divisors using base-ten blocks

IXL Practice (click on the links below)

Divide by 2-digit numbers using models

Lesson 2.4 - Partial Quotients

Students will use partial quotients to divide by 2-digit divisors.

Practice will need to be done using simple division problems on paper and pencil, as there are no IXL modules that allow practice with this method of dividing.
