About this worksheet

Adding and subtracting decimals works like whole numbers once the decimal points are lined up, so tenths meet tenths and hundredths meet hundredths. This fifth grade sheet has twenty short problems, some sums and some differences, with one or two digits after the decimal point.

Because every problem looks the same, a child can build speed and watch for the usual slip of lining up the last digits instead of the points. Each version has different numbers, and the answer key shows every answer with the shortest correct decimal.

What your child will learn

  • Line up decimal points
  • Add tenths and hundredths
  • Subtract with decimals
  • Write the answer as a decimal

Common Core standard: 5.NBT.B.7

9.7 + 1.70 = 11.4, because 9.70 + 1.70 = 11.40.
