jOb ective Relate fractions and decimals.
1. Textbook Instructions 05 Collision of Two Different Worlds
In this unit, students will learn how to relate Ricky marked a 1 L beaker with decimals, and Jessica marked it with
fractions. Fill in the blanks.

at the ten lines marked on both sides of a
beaker and write fractions and decimals.
Have them learn how to relate decimals and
fractions, which have denominators of ten. 1 1

Find how much water is in the beaker using Ricky’s marks and Jessica’s
marks. Discuss the relationship between the two marks.
Have students look at the mark to which the There is 0.4 L or 4 L of water in the beaker.
10
water is filled inside the beaker and write the Corresponding marks, such as 0.1 and 1 , have the same value.
10
decimal or fraction to show how much water
is in the beaker. Have them relate the 38
fractions to the decimals.

The Relationship Between Fractions and Decimals
Look at how Ricky and Jessica expressed the amount of water in the beaker. Jessica wrote a fraction (140 )
and Ricky wrote a decimal (0.4). 0.4 is the same as 4 .
10
Have students look at other fractions and decimals apart from 0.4 and 4 . Then have them learn the
10
relationship between a fraction with a denominator of 10 and a decimal in the tenths place.
10 0. You can change a fraction with a denominator of 10 into a decimal in the tenths place.
