BELLWORK
Match the following equations with the correct property:
1) a(bc) = (ab)c
Prop of Addition
a) Associative
1) a + b = b + a
Commutative Prop of Mult
b)
1) (a + b) + c = a + (b + c)
Addition
c) Commutative Prop of
Four Properties of Arithmetic:
If a & b are real numbers then,
The Commutative Property of Addition:
a+b=b+a
The Associative Property of Addition:
(a + b) + c = a + (b + c)
The Commutative Property of Multiplication:
ab = ba
The Associative Property of Multiplication:
(ab)c = a(bc)
Lesson 6:
Distributive Property
DATE
STUDENT OUTCOME
The student will….
Students use the distributive property
to prove equivalency of expressions.
Homework:
Pgs. S.27-S.28
Problems: 1,4a,4b,5a,5b
Honors Problems: 1-6
CLASSWORK
Exercise 2
Using the numbers 1,2,3,and 4
only once and the operations +
or x as many times as you like,
write an expression that
evaluates to 16.
Distributive Property:
If a, b, & c are real numbers
then,
a(b + c) = ab + ac
CLASSWORK
Exercise 5
Leela is convinced that
(a + b)2 = a2 + b2
Do you think she is right? Use a
picture to illustrate your reasoning.
CLASSWORK
Example 6
Draw a picture to represent the
expression and use your picture to
multiply the two expressions.
(a + b + 1) x (b + 1)
CLASSWORK
Exercise 7: Draw a picture to represent
the expression.
(a + b) x (c + d) x (e + f + g)
CLOSING
We can see, geometrically, that the following are true for whole
numbers:
Do we also believe these statements to be true for all real
numbers: a, b, c, d, e, f, g?
Which of these statements are extensions of the Distributive
Property of arithmetic (stated in your student materials)?
EXIT TICKET
Consider the expression:
1)Draw a picture to represent the
expression.
2) Write an equivalent expression by
applying the distributive property.
