Lesson

Objectives:

The students should be able to:

- Identify which geometry method is correct in solving each

problems

- Enter the correct entry of geometry symbols or sign on the

second step in the first problem.

- Solve the questions at least 2 out of 3 problems in this lesson

Lesson

Description

1. Students will take theirs seat after they enter the computer lab.

2. Instruct them to settle down while they start up their PCs.3. While waiting the PCs to be ready, ask the students about their

life and their health (just to make them to be attentive).

4. Introduce to students on the software to be used in this lesson and

then ask them to open the program on Right Triangle Solver.5. Give them a brief explanation on what they are going to do.

6. Show them one example (step-by-step procedures) as shown in

page 3.7. Give them chance to try another problem by their own.

8. Ask the students to let the teacher know if they have any

problems or do not understand on what to do and how to do.

9. Give them 15 minutes to try out several questions by themselves.

Evaluation 1. Go around and ask each of the students while they are trying to

solve the other problems.

In case of

Absence on

Internet

connection

1. Let the students enter the lab and have their seats quietly.

2. Do not allow them to switch ON their PCs.

3. Explain them on the connection problem.

4. Introduce them on the program.5. Give them notes (as in notes on next page) and explain to them.

6. Shows them another example.7. Ask them if they understand or have questions.

8. Then let them try on their own by giving them 3 questions (show

on the projector) and give them 30 minutes to answer the

questions in their exercise books (questions are in page 8)9. Then discuss their answers together and compare the real answers

with theirs.

10. Give them some questions (as h/w) and by using the program,they need to write down the answers in the h/w sheet (h/w

questions are on page 10).

Evaluation 1. This is done by marking their homework.

Notes:

The students need to know the unknown values in the diagram above and they

should now be able to choose which unknown side or angle need to be calculated. As forthe above diagram, the followings are the steps that the students need to answer.

For step 1 Solving for: (the unknown side or angle that asked in the question)

For step 2 Method: (what method is used to determine the unknown side or angle)

For step 3 Equation: (what equation is used by the method in step 2)

For step 4 Result: (solve the equation used in step 3 to the unknown side or angle).


4/15

After the students has figured out (side or angle) on which to be solved, I would

show them in step 2 Method, they will be given a lists of method to be used in solving

this problem. So they need to choose the right method and proceed to the step 3 in whichthey need to enter the letter or symbol where applicable (shown in the next page).


5/15

Now in step 3, they need to enter the correct symbols or signs in appropriate blank fields.

This is shown below.

In step 4, the students need to solve (calculate) the equation that they had

identified in the earlier step.


6/15

Click Check to find out whether our answer is correct or not. So when it is

correct, the screen will look like the following.

Step 4:

After the calculated answer has been entered, clickCheckbutton to see whether you arecorrect.

Now the students can try another problem.

(Absence of internet connection: Give the Classwork questions to the students)
