What you’ll learn

  1. The Decimal PointUnderstand the decimal point and how it separates whole numbers from smaller parts.A decimal point separates whole numbers from parts smaller than one. The digit just left of the point is the ones place; everything to the right shows fractions of a whole, like the cents in $2.50.
  2. Tenths and HundredthsIdentify the tenths and hundredths places and read the digits in a decimal.The first place right of the decimal point is tenths (0.1 = 1/10) and the second is hundredths (0.01 = 1/100). A place value chart shows each digit's place, so in 0.47 the 4 is tenths and the 7 is hundredths.
  3. Reading and Comparing DecimalsRead decimals in real measurements and compare two decimals by place value.To read a decimal, say the whole part then the decimal part. To compare, check the biggest place first: 0.5 beats 0.45 because it has more tenths. Watch out — 0.3 and 0.30 are equal, since a trailing zero adds no value.
