It is important for students to understand the basic relationship among digits in the numbers they are subtracting. When students subtract multi-digit numbers, they subtract digits at the same places to get the difference. Subtract 1-digit numbers from 3-digit numbers without regrouping worksheet provides plenty of practice with this concept. As the worksheet uses the column method, it is helpful in getting students toward higher accuracy, especially with bigger numbers and in scenarios where regrouping is required.
