The Multiplying 4 digits by 1 digit with visual models exercise appears under the 4th grade (U.S.) Math Mission. This exercise uses a visual measurement model to better understand the concepts of multiplication and place-value.
Types of Problems
There is one type of problem in this exercise:
- Multiply the numbers: This problem has a multiplication problem involving a 4-digit number and a 1-digit number. The student is supposed to break-down the values of the 1-digit number multiplied against every place value. After finding these, they can then add up these numbers to get the final product.
- Multiplying by the digit by the place values can be done easily and the model makes the product clear. The initial multiplication (the 4-digit by the 1-digit) can be done in the calculator to allow you to skip the adding step, but this ignores the spirit of practicing the distributive property.
