I created this practice worksheet for my students to practice using their strategies to subtract 2-digit numbers. This could also be used to teach the strategies initially, such as "breaking up the number". For example - 67 - 21, 67 - 40 = 80, 47 - 1 = 46!! I also have this worksheet available using different clipart for addition! These practice sheets could be good morning work, seatwork during math centers, homework or even a quiz! Enjoy!
