# Multiply 4 Digit by 1 Digit (Numbers up to 7000)

- 4th Grade MathMultiply 4 digit numbers by 1 digit numbers. In **4 Digit x 1 Digit (Numbers up to 7,000) Worksheet** students make use of area models to multiply numbers. Area models are essentially visual representation of the distributive property of multiplication. For example, 6271 x 5 can be multiplied as (6000 x 5) + (200 x 5) + (70 x 5) + (1 x 5). Fluency with place value (expanded forms), distributive property of multiplication and multiplying multiples of 10 are of great help here. This method of multiplying should act as a precursor to the standard algorithm. It is important for the students to understand how a particular method works. The 3-digit numbers in this worksheet are restricted to those between 4000 and 7000.
