Today students took the Right Triangles Test today. If you were absent you will be taking this test when we return from Spring Break. I collected the practice test which is worth a homework grade.

I will be at a teacher training for the next two days and have left plans for my sub that cover the following topics:

• Thursday - Factoring Polynomials
• Friday - Solving and Writing Linear Equations

These are two very important prerequisite skills needed for Intermediate Algebra, which the course you will be taking next year.

Today we reviewed some problems from the "Additional Practice" Worksheet. I distributed the Right Triangle Practice Test. Below are the answers to this practice test:
1.c
2. b
3. b
4. c
5. d
6. d
7. d
8. b
9. c
10. a
11. b
12. b
13. c
14. d
15. a
16. a
17. d
18. d
19. b
20. a
21. 7,191.5 feet. You will not need to do a conversion on the test
22. b

There will be very few multiple choice answer options on the actually test so be sure you are able to clearly show all work for each answer on the practice test.

We will be having the Right Triangle Test this upcoming Wednesday 3/26. The following are the topics that will be on the test

• Know when and how to apply the Pythagorean Theorem
• Know when and how to apply trigonometry to find unknown sides and when to apply the inverse function to find unknown angles
• Know when and how to apply properties of Special Right Triangles
• Be able to apply all of the above mentioned skills to word problems
• Know how to multiple and divide radical numbers to keep answers in simplest radical form.

Today in class students worked in review groups in preparation for the test. The following are the assignments they worked on.

• Textbook p. 428 #17-22
• "Additional Practice" worksheet p. 166 (handout in class)

Homework Due 3/25: Complete Additional Practice Worksheet - skip #5 only. Show all work and answers will be reviewed in class tomorrow.

Today we had a guest speaker, Dr. Gorham epidemiologist from UCSD, share with us his research on vitamin D deficiency. Students learned how our bodies make vitamin D from the sun, what happens in the body when people do not get enough vitamin D, as well as the risks associated with over exposure to sun rays. He related this information to the trigonometry students are learning in geometry.

The next unit test will take place on Wednesday and students will receive a study guide on Monday.

Today students made sun shadow boxes and recorded the length of the gnomen at each hour and half hour of the school day. Students will be using this data tomorrow in class analyze and discuss their findings.

I am not assigning new homework tonight, but if you did not complete the assignment I gave yesterday related to questions about shadows be sure to complete those questions, even if they are for half credit.

If you were absent today because of the CAHSEE or for any other reason below is the agenda for what we did today in class.

 

Email me at mrsbrown.s@gmail.com to request a copy of tonight's homework assignment. I am unable to post a pic of it here. Or you can visit @keepinggeometry100 to see a picture of it.

Today students assembled into groups for quiz 5, then worked independently on the reflection problems found on the back of the quiz. I am using quiz 5 as a formative (learning in progress) assessment so that students can assess their own areas of need.

There will be a unit test next Wednesday March 26th. Many of the topics on quiz 5 will be on the upcoming test.

If you were absent today, it is important that you see me ASAP to make up quiz 5.
