| Step / Durations | Teaching and Learning Activity | Teaching Aid | |||
| Step 1: Induction Set (5 minutes) - Construct the activity to introduce the concept of addition of vector. | - Teacher marks three points on the floor of the classroom (points A, B and C) using masking tape and a marker pen. - Teacher picks two students to demonstrate the concept of vector. - Teacher asks student 1 to walk from point A to point B and then stop at the point B. - Teacher asks student 2 to walk from point B to point C and stop at point C -Teacher asks students what are the connection between the activity and the subtopic that they are going to be learn. Suggested Questions: 1. What can you say about the activity that the 2 of your friends did just now? 2. Based on the activity just now, student 1 and student 2, walked from where to where? 3. How many steps did student 1 make from point A to point B? 4. How many steps did student 2 make from point B to point C? 5. How many steps did the 2 of your friends make from point A to point C? | · Masking Tape · Marker Pen | |||
| Step 2: Instructional Development (15 minutes) - Explains the concept of vectors in detail which is involving the operation of addition of vectors. | -Teacher explains the actual connections between the activity and the concept of vectors addition -Teacher explains that, the activity just now reflects upon the vector concept of addition because; · Two vectors or more can be combined and represented by a single vector called as resultant vector. - Teacher uses the handout to explain about the addition of the vectors. ( Refer to Appendix 1) - Teacher also draw another examples of addition of vector using whiteboard involving the triangle and parallelogram laws. | · Appendix 1 | |||
| Step 3: Evaluation (17 minutes) -Worksheet contains questions about the addition of vectors. | - Teacher asks students to find their pairs. -Teacher gives worksheet to every pair of students in the class and asks them to answer the questions. (Refer to Appendix 2) - Teacher gives 10 minutes for students to answer the questions in the worksheet. -Teacher walks around the class and help students if they need explanation. - Teacher shows and discusses the real answers of the worksheet with the students after the time is up. | · Appendix 2 | |||
| Step 4: Closure (3 minutes) - Teacher highlights the main points for today‘s lesson -Teacher gives homework to students | -Teacher asks students to summarize on what they have learned and asks them to make a conclusion about the lesson. - Teacher concludes the lesson - Teacher highlights a few points: a) In order to find the resultant vector of two vectors, the vectors have to be in the same direction b) For resultant vector of two non-parallel vectors, the vectors can be done by using triangle law and the parallelogram law. - Teacher asks students if they have any questions to be asked | · Marker pen |
