About this worksheet

Each sheet contains 20, 25 or 30 problems (your choice) and is generated at random. Press “New problems” as many times as you like; there is no limit and no account needed.

Worked example

58.72+6.20 
  1. Line up the decimal points so tenths sit under tenths and hundredths under hundredths.
  2. Work as with whole numbers: 5872 + 620 = 6492.
  3. Put the decimal point back, 2 places from the right: 64.92.

Answer: 64.92

Teaching tips

  • Insist on lining up the decimal points, not the last digits.
