Presentation transcript:

Jag Nation Pride When you enter this classroom, immediately do the following: 1.Take your seat. 2.Turn off all electronic devices and place in backpack. 3.Take out all necessary materials (planner, binder, pencil) and place back pack on floor under desk. 4.Read the Smart Board and follow all directions posted. Copy homework assignment into planner. 5.Use a white board to complete any bell work that is assigned.

BELLWORK Match the following equations with the correct property: 1) a(bc) = (ab)ca) Associative Prop of Addition 1)a + b = b + ab) Commutative Prop of Mult 1)(a + b) + c = a + (b + c)c) Commutative Prop of Addition 1)ab = bad) Associative Prop of Mult

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 = a 2 + b 2 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.
