# Multiply 3 Digit by 1 Digit (Numbers up to 1000)

- Grade 4 Math

Multiply 3 digit numbers by 1 digit numbers. In 3 Digit x 1 Digit (Numbers up to 1,000) Worksheet, students make use of area models to multiply numbers. Area models are essentially visual representation of the distributive property of multiplication. For example, 789 x 6 can be multiplied as (700 x 6) + (80 x 6) + (9 x 6). Fluency with place value (expanded forms), distributive property of multiplication and multiplying multiples of 10 will be of great help here. The 3-digit numbers in this worksheet are restricted to those between 700 and 1000.
