T3
Use formulas to calculate the area of polygons *
G.1
Lesson 1
Direct Instruction
Notes
Area (A) is the amount of space inside a flat, two-dimensional shape
Work with your seat partner to find the area of each shape. Prove your thinking in your notebooks.
Direct Instruction
Notes
Most shapes that we want to find the area of aren't drawn on a coordinate grid. For that reason, we use formulas!
Neatly write each of the five area formulas in your notebook:
Let's use our formulas to find the area of a few shapes:
Summarize
Notes
To find the area of each of the 12 shapes we drew on the coordinate plane:
1. Identify the shape and write the correct area formula.
2. To get the numbers you need for the formula, calculate the distances between points.
My Responsibilities
Due 10/7
1. In your notebook, make meaningful notes for your forgetful selves
2. CYUqs → Click the link below to open. Do your work in your notebook. Write the correct area formula and substitute. Do all 12. If you need help, get help. If someone else needs help, give help.
#5 and #6 are LEVEL 4 questions. Do your best, but feel free to work on these after you find the area of the other shapes...
Check answers as you’re working. If you make a mistake, fix it.
3. Stuck? Choose to persevere: review your thinking, try different approaches, ask for help, search
Lesson 2
After completing the Check-your-understanding Questions, which were important for everyone to do?
Review your work and discuss: what does it mean to find the area?
When you take the test for this unit, you will have two tests: computer-based and paper. For the computer based-test, you will be able to use your graphic organizer. For the paper test, you must have the five formulas memorized.
Direct Instruction
Notes
When using a formula to find the area:
1. Identify the shape and write the correct area formula.
2. Below the formula, replace the letters with the correct numbers
3. Simplify (work your way down NOT SIDEWAYS)
CYUqs
Due 10/8
Do your work in your notebook. Write the correct area formula and substitute. If you need help, get help. If someone else needs help, give help.
* If needed, use a calculator for the multiplication and division
p667: 14, 15; p665: 2, 3; p664: 2, 3 (Volume 2 Ch9-1)
p679: 14, 15; p677: 6, p676: 2, 5 (Volume 2 Ch9-2)
p689: 1, 2; p691: 15, 17; p688: 1, 2 (Volume 2 Ch9-3)
Lesson 3
Lesson 4
On the top of the blank side, write: First name, last name, U3T3
What is the area of a triangle with a base of 11 units and a height of 7 units?
Be sure to write the formula, show your work and circle your answer.
In a trapezoid, the bases are always parallel
