2. ACTIVATOR
Pick up a white board and marker Find the area of this triangle on the white board.
(-1, 9)
(7, 2)
(-1, 2)

3. OBJECTIVE(S): I will be able to:
Decompose shapes into triangles or other quadrilaterals
So that I can:
Find the area for a trapezoid by decomposing into two triangles.
Decompose rectangles to determine the area of other quadrilaterals.
I will demonstrate my understanding by solving at least 3 out of 5 real world problems independently or with a partner with at least 80% accuracy.
“break into pieces”
“a 4-side shape”
6.G.A.1

4. Language objective
By the end of the of the lesson, students will be able to use the language domains of reading and writing to communicate the academic math language of geometric shapes and sizes.
They will verbally communicate and break into pieces (decompose) shapes into triangles or other quadrilateral in order to solve the areas of trapezoids and quadrilaterals.
They will show their understanding by solving at least 3 out of 5 real world problems independently or with a partner with at least 80% accuracy.
Academic Math Language Vocabulary: triangle, quadrilateral, trapezoid, decompose

5. What do I mean…

7. Page 22 #2 I do… Total Polygon: 47.59 sq. cm 5.6 + 1.9 = ? 7.5= ? ?
decomposing…..
break apart

= ?
7.5= ? ?
Total Polygon:
47.59 sq. cm
Rectangle ABEF
7.5 * 4.8 = 36

5.6
10.9
4.8 + ? = 10.9 ?
Rectangle BCDE
1.9 * 6.1= 11.59
? = 6.1

9. Let’s look at it as a rectangle and taking away 2 triangles.
We do #4 pg. 23
Let’s look at it as a rectangle and taking away 2 triangles.
Rectangle:
A=bh
A= 18(12)
A= 216 meters2
Triangle:
A= ½ bh
h= b= (18-3)/ b= 7.5
A=1/2 (7.5)(12)
A=6(7.5)
A=45 meters2 but I have 2 triangles…
Trapezoid: A=
A=126 meters2
