I created this pack of 4 worksheets to practice adding and subtracting 2-digit numbers, with a bonus worksheet for adding 3-digit numbers. I plan to use these sheets as a review and practice at the end of the school year. I will use them for morning work, or seatwork during math centers. They can also be used for homework or a quiz or test grade! I have hundreds of math resources available for anytime of year. Check them out!
