About this worksheet

Some sums go above 100, which also introduces carrying into the hundreds place.

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

49+97 
  1. Ones: 9 + 7 = 16. Write 6 and carry 1 to the tens.
  2. Tens: 4 + 9 + 1 = 14 (including the carried 1). Write 14.

Answer: 146

Teaching tips

  • Have students say the carried digit out loud ("7 plus 5 is 12, write 2, carry 1") until it becomes automatic.
  • Write the carried 1 small above the next column.
