The distributive property is a great tool to help with mental math and simplifying larger multiplication problems. Use this scaffolded resource with your students as an introduction to the distributive property.
Multiplication is essentially repeated addition, or growing numbers by doubling, tripling, quadrupling, and so on. This unit presents mental models and strategies that help students learn and review the concept of multiplication. Students explore multiplication using arrays, partial products, doubling methods and the standard algorithm to solve numerical and word problems. Students will multiply whole numbers and simple decimals by base ten exponents (i.e. .3 x 103).

Multi-Digit Multiplication and the Standard Algorithm 2
Fifth graders are ready to learn how to multiply multi-digit numbers once they've mastered simpler problems and are looking for a challenge. Give students the practice they need to succeed with these exercises.
Multi digit multiplication is made simple with Education.com’s worksheets that clearly outline the proper order of operations, while setting the practice against the backdrop of amusing anecdotes. Stories involving slices of pizza or cake go a long way with students, and you’ll find that whether they are practicing addition, subtraction, division, or multiplication skills, adding more digits won’t prove a problem as long as students are entertained.
After learning one-digit multiplication and becoming comfortable with it, your students will be able to move on to multi-digit multiplication. While this concept may be daunting to early learners, they will soon understand that each multi-digit multiplication problem can break down into a series of single digit and addition problems.
One way to solve multi-digit multiplication problems is the area model. This helps students visualize the problem they are solving by breaking up each part of the problem clearly. The area model method involves drawing a grid, with one column for each of the digits in one of the factors, and rows for each of the digits in the other. For example, if your students are solving 16 x 27, they would have a grid with 4 cells divided between two rows and two columns.
On top of each column, they would write the number represented by each digit in the factor. In our example, they would write 20 over the first column, and 7 over the second. To the left of each row they write each number in the other factor, 10 and 6 in our example. Inside of each cell, have your students write the product of the two numbers that intersect at that cell. Adding all of the resulting products together will give them the final product of the original problem.
Practicing this method using the resources provided by Education.com may help your students enhance their understanding of solving multi-digit multiplication problems using the area model.
