Different Ways to Compare Decimals Using Place Value
0.78 > 0.39 since 7 tenths > 3 tenths 
0.78 > 0.39 since 78 hundredths > 39 hundredths 
Comparing Using A Benchmark Number and/or Number Line 
0.15 < 0.7 since 0.15 <0.5 and 0.7 > 0.5
0 
0.1 
0.2 0.3 0.4 0.5 
0.6 
0.7 0.8 0.9 1.0

Using 0.5 as benchmark 
5N10.4 Order a given set 
of decimals by placing them 
on a number line (vertical or

General Outcome: Develop Number Sense
Performance
• 
Give students the following blank game board.
Roll a die. As the number is called, ask each student to write it 
in a blank square on his/her board. Roll the die 18 times. The 
student(s) who create(s) three true sentences wins the round. Repeat 
the process. Circulate during the play asking questions and noting 
students’ justification of position choice. Students could be asked to 
write any strategies they used on chart paper and a class discussion 
could follow.
(5N10.1, 5N10.2)
Math Focus 5
Lesson 10: Comparing and 
Ordering Decimals
TR: pp. 59-62
SB: pp. 70-72
Note
Using equivalent decimals to 
compare is not directly addressed 
in the text, however, the concept 
of equivalent decimals has been 
developed in Lessons 7 and 8.
• 
Give students eight index cards with a decimal number to tenths 
on each. Ask them to challenge a partner to order the number cards.
Repeat activity using decimal numbers to hundredths and to 
thousandths.
(5N10.1, 5N10.2, 5N10.3)
• 
Give students the number cards 0.99, 0.987, 0.9 and 1.001, and ask 
them which decimal number they think is closest to 1. Have them 
explain how they made their decision.
(5N10.4)
• 
Give students the number cards 9.023, 10.9, 9.05, 10.11 and 9.8, 
and ask them which decimal they think is closest to 10. Have them 
explain how they made their decisions. 
(5N10.4)
Paper and Pencil
• 
Provide examples of some of the best javelin throw distances that 
have occurred in past Olympics, e.g.,
1972: 90.48 m 1980: 91.20 m 1988: 84.28 m 1992: 89.66 m
Ask students to arrange the distances in order and determine whether 
records always improve.
(5N10.2)
