1. QDN Week #9
Ending Unit 8 Angle Relationships, Beginning Unit 9 Circles, Surface Area and Volume

2. IWBAT identify Angle Relationships with 80% accuracy BTEOC (measured by Kahoot).
Quiz 5/22 Classify the following Angle Relationships.
Do Now 5/22 Classify the following Angle Relationships.

3. IWBAT solve equations with variables on both sides BTEOC
IWBAT solve equations with variables on both sides BTEOC. (measured by Kahoot)
Quiz 5/23 Distribute, Isolate the x variable, add, then divide by the coefficient. 4(x − 5) = x x − 20 = x + 19 subtract x from both sides 4x – x = 3x and x – x = 0 3x − 20 = 19 3x − = Add 20 to both sides 3x 3 = 39 3 divide by a coefficient x = 13 variable is isolated
Do Now 5/23 Solve for x, and find the measure of the Supplementary Angles. (26 + 6x)° 22° 26 ° + 6x ° + 22° = 180 ° 6x + 48 = 180 subtract 46 from both sides 6x = 180 – 48 6x 6 = x = 21

4. IWBAT solve Complementary and Supplementary Angle relationships BTEOC (measured by Kahoot)
Quiz 5/24 Write an equation that represents each diagram and solve for x x = 90 3x + 36 – 36 = 90 – 36 3x 3 = 54 3 X = 18°
Do Now 5/24 Write an equation that represents each diagram and solve for x x = 43 2x + 23 – 23 = 43 – 23 2x 2 = 20 2 X = 10°

5. IWBAT calculate the Area and Circumference of a Circle BTEOC.
Quiz 5/25 Janet sells erasers at a price of 8 erasers for 60 cents.  She started this table to show the price for different numbers of erasers. Complete the table.
Quiz 5/25
𝐴=𝜋 ·𝑟 2 or 𝐴= 𝑟 2 ·𝜋
Calculate the area of a circle with a radius of 9 in. Use 3.14 for 𝜋.
A = 𝜋 x 92
A = 𝜋 x 81 or 3.14 x 81
A = in2
Rounded to the nearest hundredth place.

6. IWBAT figure out the Surface Area of a Rectangle Prism using 2 methods BTEOC.
Quiz 5/26 Find the total surface area of the rectangle prism. Top = 2(12 x 3) = 2(36) equals 72 Front = 2(12 x 4) = 2(48) equals 96 Side = 2(4 x 3) = 2(12) equals 24 Add up all the sub-areas to get = 192 cm2
Do Now 5/26 Find the total surface area of the rectangle prism. Method #2 Add the Base Perimeter is = 14 in. Perimeter x Height = 14 x 5equals 70 Add Base Area (top and bottom) 2(12) = 24 Total Surface Area = or 94 inches 2 Method #1 Top 2(4 x 3), Front 2(4 x 5) Side 2(5 x 3) = 94 inches 2
