Subtract 1 Digit from 3 Digit Numbers

- 2nd Grade Math

Practice subtracting 1 digit number from a 3 digit number. This is the same as reducing the number of ones in a number and should be simple for students with a clear understanding of place value concepts. Although the 3 Digit Minus 1 Digit Subtraction Worksheet starts off with problems that use models for numbers, students should target being mentally proficient. Building mental fluency in such special cases of subtraction helps to contribute towards overall proficiency in subtraction.
