2. Weekly Agenda Monday: MobyMax – Math
Tuesday: Distributive Property and other Properties
Wednesday: Evaluate when…
Thursday: Factoring and a Quiz
Friday: MobyMax – Fact Fluency

3. Distributive Property
To multiply a number by a sum of two terms, you can multiply that number by each term and add the two products.
a(b + c) = ab + ac
3(7 + 5) = 3*7 + 3*5

4. Distributive Property
5 ( 6 + M ) 9) -2 ( -6 + S )
-5 ( 6 + M ) 10) -5 ( -5 + W )
3 ( 5 + T )
8 ( 4 – Y )
-8 (4 – B )
2 ( 3 + 2K)
2 ( R )
- 2( 6 + F )

5. Commutative Property
The sum of two numbers is the same no matter which order is used to add them.
a + b = b + a
3 + 7 = 7 + 3
Also applies to multiplication.
A * B = B * A

6. Associative Property
The sum of three numbers is the same whether you group the first two numbers or the second two numbers.
(a + b) + c = a + (b + c)
(3 + 7) + 5 = 3 + (7 + 5)
Also applies to multiplication.
(3 * 7) * 5 = 3 * (7 * 5)

7. Tuesday
Simplify and Combining Like Terms.

8. Let’s try to simplify: 6T – 3T 5A + 6 – A 8Y + 14 + 10Y – 2
6R + 8S – 4 – 4R +2S + 8
3W – 6X + 2 – 5W + 4X + 7
Find like terms, combine like terms, write the simplified expression.

9. Combine Like Terms (Simplify)
5R – 4R – 7R
8G + 9G – 4G
5R – 4R – 7R + 8G + 9G – 4G
9B + 5B – 6B
8H – 3H + 4H
9B + 5B – 6B +8H – 3H + 4H + 7

10. Wednesday
Evaluate when…

11. Combine Like Terms (Simplify)
5R – 4R – 7R
8G + 9G – 4G
5R – 4R – 7R + 8G + 9G – 4G
9B + 5B – 6B
8H – 3H + 4H
9B + 5B – 6B +8H – 3H + 4H + 7

12. Thursday

13. Factoring 5(2B + 4) 5(2B) + 5(4) 10B + 20
Find a common factor of 10 and 20 = 5 So
5(2B) + 5(4)
5(2B + 4)
