TEKS 8.6A, 8.7B
The Core: V = Bh
Find the Base Area (B) first, then multiply by the height of the shape.
1 Cylinder: πr2h
2 Cone: 1/3 πr2h
3 Sphere: 4/3 πr3

"Cones are 1/3 of a Cylinder!"
Pythagorean Theorem
TEKS 8.7C: Right Triangles Only
a2 + b2 = c2
Hypotenuse (c )
The longest side. Always opposite the 90° angle.
Legs (a, b )
The two shorter sides forming the right angle.
Equation Lab
TEKS 8.8A: Both Sides Balance
01
Cleanup
Distribute and combine like terms on each side.
02
Migrate
Move the smaller variable term using inverse operations.
03
Isolate
Solve the final 2-step equation to find x .
Example: 2(x + 5) = 4x - 2 x = 6

Dilations
The Mapping Rule:
(x, y) → (kx, ky)
k > 1 : ENLARGE
k < 1 : REDUCE
Reflections
x-axis: (x, -y)
y-axis: (-x, y)

Slide: (x + a, y + b)
Dilations change size. Others stay CONGRUENT!

Facilitation Tips
Ensure students calculate B (Base Area) before multiplying by height for all volume problems.
For equations, move the smaller variable first to avoid negative coefficients.
Key: Missions 1 & 2
01. Volume (8.7B)
Inputs
r = 10, h = 30
V = πr2h
V = 3.14 × 102 × 30
V = 314 × 30
Ans: 9,420 ft3
02. Geometry (8.7C)
Inputs
c = 13, a = 5
a2 + b2 = c2
52 + b2 = 132
25 + b2 = 169
b2 = 144 → b = 12
Ans: 12 ft
Key: Mission 3
03. Balancing (8.8A)
1. 2x + 10 = 4x - 2
2. 10 = 2x - 2
3. 12 = 2x
4. x = 6
Final Result
x = 6

Dilation Analysis
"If k=3 and k=1/3, how does this prove they are inverse dilations?"
Sphere Proof
"If a sphere and cone both have radius r and height r , prove the sphere is 4x the cone."
