1. Perimeter & Area of Parallelograms, Trapezoids, Rhombi & Kites.
Compose and decompose two- and three-dimensional figures; use decomposition to determine the perimeter, area, surface area and volume of various figures

2. Guiding Question: How does perimeter/area change with different 2-d shapes?
Lesson Obj: IWBAT decompose a 2- d shape to find its perimeter and area.
What is the difference between a parallelogram, a trapezoid, a rhombus, and a kite?

3. Guiding Question: How does perimeter/area change with different 2-d shapes?
A parallelogram looks like someone tried to push over a rectangle. Finding the perimeter is exactly the same.
P = 2l + 2w
The height is no longer the side of the shape. Area is still base x height.

4. Trapezoid: 1 pair of parallel sides.
Guiding Question: How does perimeter/area change with different 2-d shapes
Trapezoid: 1 pair of parallel sides.
Perimeter: Find the sum of all sides
Area: add the bases(parallel sides), divide by 2, multiply by height.

5. Guiding Question: How does perimeter/area change with different 2-d shapes
Rhombus: 4 equal sides, diagonals are perpendicular, diagonals bisect
Kite: 2 sets of congruent sides, diagonals are perpendicular

6. Guiding Question: How does perimeter/area change with different 2-d shapes
How can we find the perimeter and area of this rhombus?
What is the area of this kite?

7. Guiding Question: How does perimeter/area change with different 2-d shapes
Calculate the perimeter and area of this rhombus.

8. Guiding Question: How does perimeter/area change with different 2-d shapes
A baseball diamond is a rhombus with each side being 90 feet (between the bases). What is the perimeter (distance around the bases) & the area inside of the diamond?
