Predict the result
Chapter 1 connects decimals, fractions and percents.
How would you name these four decimals?
Look at the place of each last digit.

Set up the model
Read the whole-number part, then the decimal part.
Tenths, hundredths, and thousandths are different sizes.

Work the example
Four point three is four and three tenths.
Two point four five is two and forty-five hundredths.
Zero point zero zero nine is nine thousandths.
Negative fifteen point five seven one is negative fifteen and five hundred seventy-one thousandths.

Check the result
Now name six point seven, nineteen point five eight,
zero point zero one eight, and negative two point zero five three.
Take eight seconds to think before the answer appears.
[Eight-second silent pause to work; the answer remains hidden.]
The names are six and seven tenths, and nineteen and fifty-eight hundredths.
The last two are eighteen thousandths, and negative two and fifty-three thousandths.

Interpret the result
Naming place value prepares you to compare and round decimals.
Use the original task and check that your result fits its meaning.
