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 Property The 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!
