This worksheet challenges young mathematicians to hone their math skills by solving a set of problems on subtracting two 5-digit numbers without regrouping. 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 two 5-digit numbers without regrouping worksheet provides plenty of practice with this concept. This worksheet is about practicing the column method in which numbers are written one on top of another. In this method, students use their place value understanding to solve the problems.
