Standards Addressed:
5.1
The student will
a) read, write, and identify the place values of decimals through thousandths;
b) round decimal numbers to the nearest tenth or hundredth; and
c) compare the values of two decimals through thousandths, using the symbols >, <, or =.
Pre-Assessment: www.thatquiz.org review assignment on decimals.
Defining the Learning Goals: What the student will:
Know (Facts/Vocabulary):
 A decimal point separates the whole number places from the places less than one. Place values extend infinitely in two directions
from a decimal point. A number containing a decimal point is called a decimal number or simply a decimal.
 To read decimals,
– read the whole number to the left of the decimal point, if there is one;
– read the decimal point as “and”;
– read the digits to the right of the decimal point just as you would read a whole number; and say the name of the place value
of the digit in the smallest place.
 Decimals can be rounded to the nearest tenth or hundredth in situations when exact numbers are not needed.
 A strategy for rounding decimal numbers to the nearest tenth and hundredth is as follows:
– Look one place to the right of the digit to which you wish to round.
– If the digit is less than 5, leave the digit in the rounding place as it is, and change the digits to the right of the rounding place
to zero.
– If the digit is 5 or greater, add 1 to the digit in the rounding place and change the digits to the right of the rounding place to
zero.
 A procedure for comparing two decimals by examining place value may include the following:
– Line up the decimal numbers at their decimal points.
– Beginning at the left, find the first place value where the digits are different.
– Compare the digits in this place value to determine which number is greater (or which is less).
– Use the appropriate symbol > or < or the words greater than or less than to compare the numbers in the order in which they
are presented.
– If both numbers are the same, use the symbol = or words equal to.
– Two numbers can be compared by examining place value and/or using a number line.
Understand (Big Ideas):
 Decimals are one way to represent parts of a whole and are used in our everyday lives with money and
fractions.
Do (Specific Skills student is able to do after the lesson):

Identify the place values for each digit in decimals through thousandths.

Read decimal numbers through thousandths from written words or place-value format.

Write decimal numbers through thousandths from written words or from decimal numbers presented orally.

Round decimal numbers to the nearest tenth or hundredth.

Identify the symbols for the terms greater than, less than, and equal to.
 Compare the value of two decimal numbers through thousandths, using the symbols >, <, or =.
Materials/Supplies: computers, website www.thatquiz.org, pencils, paper, place value chart, base ten
models of tenths, hundredths, thousandths
Procedures/Activities (Include Marazano's Strategies and Bloom's Taxonomy):
Day 1: Review place value chart and remind students that this is found both in the book and in their daily
planners.
Day 2: See menu below

interest X learning profile
Why (What prompted you to differentiate in this way)? As I have begun to review for the SOL test, I was
surprised to find that many students do not remember the place value chart. This tells me they truly did not
“learn” it. Therefore, I am doing something to make it more meaningful to them.

Choose one activity from below. Be sure to include the activity name on the back of your project.

Poster
Create poster of a place value chart with at least
10 numbers containing both whole and decimal
digits. The number of digits per number doesn’t
matter, but the positions millions through the
thousandths must be represented.
Underline 1 digit in each number.
Below the poster, copy each number in order from
least to greatest. Name the place value position of
the underlined digit, its value, and round the
number to the underlined position.
*Be sure to use a ruler and make your poster neat
so that your classmates will want to look at it as a
learning tool.

Lesson Plan
Prepare a lesson plan for teaching the place value
chart and rounding numbers in the chart to the
position of the underlined digit to students who
may not understand it. Your lesson must
represent the millions through the thousandths
place. You may use the index of your math book
to give page numbers to your students. You may
also tell them what page the chart is on in their
daily homework planners. Explain to them step
by step how to name the position of a number, its
value, how to compare them, and how to round
numbers. You may do this as part lecture, but
you probably want some type of graphics for this,
even if it’s just a place value chart.
Teach your lesson to a partner.
NT
Compare/Contrast
Compare and contrast whole numbers versus
decimal numbers. Be sure to include the positions
from the millions place to the thousandths place.
This could be done on a Venn Diagram, or in
paragraph form. (You will have a hard time
finding likenesses. That’s fine, but think hard
about the differences).
Beneath this diagram, list 5 numbers in order
from least to greatest, underline one digit in each
number, and tell its position, its value and round it
to the underlined position.

Kidspiration
Use Kidspiration to create a lesson on the place
value chart with at least 5 numbers with both
whole and decimal digits from the millions place
through the thousandths place. Underline 1 digit
in each number and have a comic character from
the program in your “lesson” who explains the
value of each underlined digit. Put your numbers
in order from least to greatest somewhere below
your chart. Also have the character explain the
process of rounding the number to the position of
the underlined digit.
*Print out your document.
