2nd Semester Review Jeopardy Game!!!!!!!!!!!!!

It's here........The 2nd Semester Review Jeopardy Game! Take some time to review the questions and try to answer them, then you can check your answers on the game. This will be a great tool to prepare for the semester exam next week.

11.3: Area of Sectors and Arc Length

In section 11.3 you will be find the area of a sector, or the area of a section of a circle, like a piece of pie. You will also be finding the arc length on a circle. To find the area of a sector in a circle or the arc length of a circle you will be setting up proportions.

As you read through the section below fill in the blanks on the handout that has been provided for you.

Area of Sector:

To find the area of a sector you will set up a proportion following the pattern part/whole = part/whole. On one side of the proportion the part will be the angle of the sector and the whole will be 360 degrees, because the total angle measure of every circle is 360 degrees. On the other side of the proportion will be the unknown area of the sector we are looking for and the total area of the circle. Once you have the proportion filled in you cross multiply and divide. Take a look at the examples on the following site to help illustrate this, don't worry about watching the videos, just take notes on the examples.

Arc Length:

Earlier in this chapter we discussed finding the angle measure of an arc on a circle, now you will be finding the length of an arc on a circle. This means it will be a distance that can be measured in units such as inches or centimeters, not degrees. To find the arc length you need to set up a proportion. You will start to set it up similar to the explanation above for finding area of a sector. On one side of the proportion you have the angle measure of the arc over 360 (the total angle measure of any circle). Next, this equals the unknown arc length (x), over the total circumference of the circle (use the equation for circumference of a circle). Cross multiply the two ratios and divide to find the arc length. Use this site to help describe this explanation, don't worry about watching the videos.

PACE: Study Techniques

Click the link below and read the section of study techniques that have been assigned to your group. Be prepared to give a short presentation about the main ideas in your reading. Make sure the information you tell the class will be helpful and relevant to high school students.

Preparing for the vocabulary test

There will be a vocabulary test over words from chapters 6 and 9. Here is the link to Quizlet that will have all the words on the test and their definitions:

The assessment will be on Friday and Monday, the 18th and the 21st.

Ch. 9 Area and Perimeter

Here are some videos that you might want to watch from the Khan Academy. There are three videos about area and perimeter of different shapes. Pick the ones that would be most beneficial to you.

Area and perimeter of rectangle and triangles:

Circles: Radius, Diameter, and Circumference:

http://www.khanacademy.org/video/circles--radius--diameter-and-circumference?playlist=Geometry

Area of Circles:

http://www.khanacademy.org/video/area-of-a-circle?playlist=Geometry



Take a look at one, two, or all three of these to see if they help you understand area and perimeter of shapes better.

Semester Average

Hello there everyone! I just wanted to remind my students to study-study-study for the semester exam next week. It counts for 25% of your overall grade, so use the semester review packets that you received during class.

If you want to calculate the grade you will need on the semester exam to pass for the semester just subtract your three grades that you earned from the past 3 6-weeks from 280. For example, 1st 6-weeks = 75, 2nd 6-weeks grade = 80, and 3rd 6-weeks grade = 83. Take your 3 grades: 75, 80, and 83 and subtract them from 280 (280-75-80-83). It equals 42. You need to get a 42 on the semester exam to pass the class for the semester with a 70.

Come to tutoring after school with your questions and I will help you find the answers.

After the Chapter 4 Assessment

After the chapter 4 assessment go to quizlet using the link provided and study the vocabulary words from chapter 7. You are also going to create a foldable of these words to be stapled into page 30 of your notebook. Fold your paper and design it using the example that is taped on the wall back by the notebooks. Copy the definitions on Quizlet into your foldable under the column labeled "definition."


Make sure to staple it into page 30 or your notebook, this will be your ticket out of here.

Finished with writing the definitions?
