92. We call these pieces TENTHS Next Home

93. When we write a decimal, we write the whole number before the decimal point and the tenths after the decimal point. For example: 0.30.4 3 is in the tenth column- 3 tenths 4 is in the tenth column- 4 tenths Next Home

95. 0.3 Next Home

96. 0.4 is 4 tenths, so we need 4 of the smaller tenth pieces Next Home
