These worksheets provide students with the opportunity to demonstrate their understanding of adding two- and three-digit numbers by requiring them to fill in the missing numbers in addition problems.
This gives students an opportunity to practice both addition and subtraction and reinforces the inverse relationship between these two basic operations.
Worksheet 1: This worksheet contains 16 two-digit by two-digit addition problems of increasing difficulty.
Worksheet 2: This worksheet contains 8 three-digit by three-digit addition problems of increasing difficulty and a challenge question with a 5-digit number added to a 4-digit number.
