The distributive property of multiplication for 3rd-grade math makes it easier for students to solve bigger multiplication problems they wouldn't normally be able to solve.
The property states that when a number is multiplied by the sum of two numbers, the first can be distributed to both of those and multiplied by each separately, then adding the two products together.
What is the Distributive Property of Multiplication?
The distributive property of multiplication states that when a number is multiplied by the sum of two numbers, the first can be distributed to both of those and multiplied by each separately, then adding the two products together.
First, we "break-up" one of the factors to make it easier for 3rd-graders to multiply. If a student is given the multiplication sentence 8 × 16, it is much easier for the student to "break up" the factor 16.
For example:
8 × (10 + 6)
Next, the student will distribute the 8 to the addends and write a new expression.
(8 × 10) + (8 × 6)
Last, solve the equation.
80 + 48 = 128
As you can see, "breaking-up" the factor 16 and distributing the 8 to each addend made the problem much easier to solve. A student does not necessarily have to break 16 up into 10 and 6, but it most cases it is the logical way.
Distributive Property of Multiplication Worksheets for 3rd-Grade
Truthfully, there aren't many distributive property worksheets out there that I like so I decided to make my own! If you are looking for worksheets that introduce the distributive property of multiplication for your 3rd-graders, the set below is great!
Distributive Property of Multiplication Activities for 3rd-Grade
These distributive property of multiplication activities for 3rd-grade are an engaging way for students to practice the property. The unit comes with a matching game and task cards. They are simple, but effective math centers that will make your life easier. The game and task cards teach the property, hit the standard, and they're fun!
"Breaking up" or "breaking apart" seems to be one of the harder steps. Students can can get ready for the "breaking up" step with this matching worksheet.
The sad truth is that their isn't many activities out there for the distributive property of multiplication. As a mathematics teacher-author I am trying to change that. Check out this unit I created for the distributive property.
As teachers it our chance to change the negative stigma on math. I remember, after 3rd-grade I hated math. It wasn't until a college class I took at a local community college that I learned to appreciate mathematics. My teacher brought in Dollar Store erasers to explain something. She changed my life with those little erasers... she probably doesn't even know.
