1. Sharing on the implementation of Major concern Pre-lesson Tasks Mathematics Department

2. Purposes of pre-lesson tasks in Mathematics
1. Basic Knowledge Review
Brief notes or simple mathematical
questions aim at recalling students’ memories of the prerequisite knowledge, formulas or
mathematical terminology learnt in the junior form.
e.g. Secondary 5 Variation
Revision of rate, ratio & percentage

3. Secondary 5 S1

6. Purposes of pre-lesson tasks in Mathematics
2. Exploration (Arousing students 'interest)
Watching TWIG film or doing inspiring activities that can motivate students to explore mathematical concepts and experience the process of constructing new knowledge such as deriving new formula on their own.
e.g. Secondary 6
Summation formula of Arithmetic Sequence

7. Secondary 6

10. Purposes of pre-lesson tasks in Maths
3. Self-directed learning
Students are required to study the content in their textbook (new knowledge) on their own. Then, they will act as a teacher to teach their classmates during the lesson.
e.g. Secondary 3 Hexadecimal system

11. Secondary 3

15. Example (Junior level)
Level : Secondary 2
Topic: Solving simultaneous linear equations by the method of elimination
Implementation:
Before the lesson
1. Students are required to finish a worksheet.

16. Example (Junior level)
2. The questions in the worksheet guide students to acquire new techniques through step-by-step explorations.
Firstly, the question involve numbers only. It is easier for students to handle.
Then, the questions involve variables.
Finally, students have to draw a summary of what they have acquired.

17. Secondary 2

19. Example (Junior level)
Implementation:
During the lesson
1. Students are asked to display their answers and report what technique they have acquired.
2. During the oral presentation, other students are invited to give comments and suggestions. The teacher also give feedback to help students identify their weaknesses and mistakes.
3. Then, students use the new technique to solve simultaneous equations.

20. Example (Senior level)
Level : Secondary 4
Topic: Equations of straight lines
Implementation:
Before the lesson
1. Students were required to watch two videos (3 mins + 10 mins) and finished a pre-lesson worksheet before lesson.

21. Secondary 4 https://www.youtube.com/watch?v=3mHsCqU_wAU

24. Exemplar 2 Implementation: During the lesson
1. Students were asked to complete a pre-study quiz
2. Teachers check whether students can applied the formula learnt in the pres-lesson worksheets.
3. A Student were asked to present his answer to the whole class.

25. Evaluation Students are activated to learn the new knowledge.
Students attend the lesson with questions in mind.
Less-able students are better prepared for the lesson.
Having a brief understanding before the start of a new topic enables student to acquire new knowledge better and faster.

26. Difficulties Learner diversity
Some students do not do pre-lesson tasks
Lazy
Incapable
Manageable tasks
Should we teach students during lesson if they haven’t done the pre-lesson tasks?

27. Solutions
Classroom activities
- Oral presentation
- Quiz
