Rewrite a fraction with a denominator of 10 as an equivalent fraction with a denominator of 100. Look at the base ten blocks. The ONE is cut into 10 pieces which are each cut into 10 pieces. That means there are 100 cubes in the WHOLE ONE flat X 10 = 100 ONE FLAT TEN RODS CUBES WHOLE TENTHS HUNDREDTHS

93 thirty-nine hundredths and can be written as 39/100
Students will translate the word form of a decimal into its equivalent fraction. 0.39 reads thirty-nine hundredths and can be written as 39/100 0.71 reads 0.28 reads 0.46 reads 0.05 reads 0.99 reads

95 0.94 reads 0.26 reads 0.82 reads 1.05 reads 0.60 reads 0.45 reads

96 you have an IMPROPER FRACTION
Students will translate fractions greater than ONE with denominators of 10 and into equivalent decimal form. When the NUMERATOR is larger than the DENOMINATOR you have an IMPROPER FRACTION resulting in a whole number on the LEFT and a decimal fraction on the RIGHT.

97 Let’s translate some improper fractions into decimals. 13/10 = 1.3
13/10 = 1.3 Because the numerator: 13 is larger than the denominator: 10, we have an improper fraction - meaning that we have a WHOLE number and a part. 11/10 26/10 32/10 18/10

98 29/10 45/10 10/10 100/10 82/10 55/10 90/10 64/10 71/10 33/10 15/10 84/10

100 Students will represent a decimal value on a number line.
What decimal does each dot represent? 0.2

101 What decimal and fraction does each dot represent?

102 Complete each fraction on the number line. Several are done for you.

103 P = _____ Q = _____ R = _____
Label the value of each dot on the number line. P = _____ Q = _____ R = _____

104 Label each decimal value on the number line. 0.32 0.59 0.11 0.75

105 Label each decimal value on the number line. 0.02 0.93 0.67 0.24

106 Label each decimal value on the number line. 0.46 0.88 0.23 0.67

107 Label each fractional value on the number line

108 Label each fractional value on the number line

109 Label each fractional value on the number line

110 Students will explain their thinking when labeling a decimal fraction on a number line. “I think that 32/100 is more than 30/100 (3/10) and that it is less than 40/100 (4/10). So I think it will be closer to 30/100. I would place it on the number line near that value.”

114 Students will explain that decimals can only be compared when they refer to the same whole.
Students will compare decimals with and without models and record the comparison numerically using symbols < = > Students will justify the comparison by reasoning about the size of the decimal or by using a visual model. MAFS.4.NF.3.7

115 This is a candy bar. It is divided into 10 equal pieces
This is a candy bar. It is divided into 10 equal pieces. This is a candy bar. It is divided into 10 equal pieces, too. We CAN NOT compare them because they are NOT THE SAME! Each model shows 10/10 but the whole Hershey’s is much bigger than the other candy bar so these decimals can not be compared.
