Expressions and Equations
6.EE.3 Distributive Property
Looking at Area
Area of a rectangle can be written as an expression of the length x width or lw. One or more of the dimensions may even be represented with a variable.
Write the expressions for #1-7 on your worksheet.
Looking at length
The length of a segment that has two parts can be written as a sum….
Complete # 8-10 on your worksheet.
Putting it Together
The area of a rectangle made of two rectangles can be written two ways:
– As a product written as the expression w (l + l)
– As a sum of the two rectangles lw + lw
Complete #11-13 at your tables and compare answers.
The Distributive PropertyThe Distributive Property allows us to write equivalent expressions:
Practice and Apply
Try this: Use the distributive property to rewrite each as a sum.
#14 4(x + 7) = #15 7(x - 3) =
Now complete #16-21 on your own. Your teacher will tell you to change questions #16 and #20. Listen carefully!
