Standard: 5.NBT.B.7
Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and
strategies based on place value, properties of operations, and/or the relationship between addition and
subtraction; relate the strategy to a written method and explain the reasoning used.
Description
TASK: The purpose of this task is for students to
add, subtract, multiply, and divide decimal
numbers in a real-world context.
LESSON: Addition of decimals using a variety of
strategies and models. This lesson builds on the
students' understanding of whole number addition
and relates it to addition of decimals. In this
lesson, students will use a variety of strategies to
add decimals and whole numbers. Strategies may
include, but are not limited to: number line
diagrams, base ten models, decimal grids, and the
standard algorithm.
LESSON: Subtraction of decimals using a variety
of methods. This lesson will build on students
understanding of whole number subtraction and
apply it to decimal numbers. Students should be
able to apply the strategies they have for whole
number subtraction to the numbers in the task for
this lesson.
LESSON: Multiplication of decimals using an
area model.
LESSON: Multiplication of decimals using a
variety of strategies.
LESSON: Find fair share of decimals using
knowledge of division
LESSON: Students will explore how to apply
whole number division strategies to decimal
division.
LESSON: In this task students apply their
understanding of whole number operations to
decimals. They reason about the relationship
between whole numbers and decimals and
understand that the quotient is larger than the
dividend when dividing by a decimal.
ACTIVITY: In this activity, students will practice
their understanding of decimals.
TASK: Adding decimals using base 10 blocks
TASK: Subtracting decimals using base 10 blocks
TASK: Subtracting decimals using a variety of
strategies.
TASK CARDS: Word problems for decimal
multiplication.
TASK: Multiplying decimals using a number line.
TASK: Multiplying and dividing decimals to find
gallons of gas needed for a trip and cost of
gasoline for a trip
