  1. Day 4 Distributive Property

  2. Review number properties • https://www.youtube.com/watch?v=7HFRH_M1nAc

  3. 1-3 Algebra Lab – AccuracyGroups of 5 1.Elan has $13 that he wants to divide among his 6 nephews. When he types 13 ÷ 6 into his calculator, the nuber that appears is 2.16666667. Where should Elan round? 2. Dante’s mother brigs him a dozen cookies, but before she leaves she eats one and tells Dante he has to share with his two sisters. Dante types 11 ÷ 3 into his calculator and gets 3.666666667. Where should Dante round? 3. Eva measures the dimensions of a box as 8.7, 9.52, and 3.16 inches. She multiplies these three numbers to fine the measure of the volume. The result shown on her calculator is 261.72384. Where should Eva round?

  4. Distributive PropertyUse the distributive property to evaluate expressions Use the distributive property to simplify expressions John burns approximately 420 calories per hour by inline skating. The chart below shows the time he spent inline skating in one week. There are two methods you could use to calculate the number of Calories John burned inline skating.

  5. Distributive Property The D Property - A song about the Distributive Property http://www.youtube.com/watch?v=yZCO4t https://www.youtube.com/watch?v=ydc4lrWaDh4

  6. Use the property to perform mental math • Example • 7 · 49 = 7 (50-1) • Try these: a. 304 (15) c. 210(5) b. 44 (2 ½) d. 52(17)

  7. Real World Example #1A group of 7 adults and 6 children are going to a University of South Florida Bulls baseball game. Use the Distributive Property to write and evaluate an expression for total ticket sold.

  8. Try this: • A group of 3 adults, an 11 year old and 2 children under 10 years old are going to a baseball game. Write and evaluate an expression to determine the cost of tickets for the group.

  9. Algebraic expressions • 7(3w – 5) (6+ v – 3)4 • Try these: (8+4n)2 -6(r+3g –t) (2-5q)(-3) -4(-8 – 3m)

  10. Simplying algebraic expressions • Simplify 17u + 25 u Simplify 6+3t –t • Try these: • 6n – 4n + 13b + 13 • 4 + 2y – 8y + 5 7a + 4 - 6 - 2a

  11. Write and simplify the expressions: • Twice the difference of 3x and y increased by five times the sum of x and 2y. Try this: 5 times the difference of q squared and r plus 8 times the sum of 3q and 2r

  12. Review of propertiesFill in the chart
