Teaching-Learning Procedure
| Step | Teaching-Learning Strategy | Resources Used | Purpose |
|---|---|---|---|
| 1. EXPLAIN | Explain average using examples of marks and scores. Introduce the formula: Average = Sum of all quantities ÷ Number of quantities. Explain the direct unitary method by finding the value of one item first and then calculating the value of the required number of items. | Interactive board and SpeedUpScience blog | Build conceptual understanding. |
| 2. VISUALISE | Display worked examples, number sets, marks and price lists on the interactive board. Use relevant explanations and practice examples from the SpeedUpScience blog. | Interactive board and SpeedUpScience blog | Help students understand the steps visually. |
| 3. CONNECT | Connect average with marks and quiz scores, and the unitary method with shopping and prices. Ask 5W1H1U questions: What, Why, When, Where, Who, How, and How much/How many. Encourage students to explain their reasoning. | Interactive board, blog examples and oral questioning | Connect mathematics with everyday life. |
| 4. REVISE | Display formulas and solution steps on the interactive board. Students summarise the concepts through a simple mind map in their notebooks and explain the steps in their own words. | Interactive board and SpeedUpScience blog | Strengthen recall and understanding. |
| 5. PRACTISE | Students solve textbook questions and relevant practice questions or MCQs from the SpeedUpScience blog. Display selected questions on the interactive board and discuss common errors. | Interactive board, SpeedUpScience blog and notebooks | Improve accuracy and independent problem-solving. |
| 6. CONSTRUCT | Students create their own word problems based on average or the direct unitary method. In pairs, they exchange questions, solve them and explain their methods. | Interactive board for prompts and student notebooks | Develop creativity, collaboration and mathematical communication. |
| 7. APPLY | Conduct a mini shopping activity using a price list displayed on the interactive board. Students calculate the cost of different quantities. They also calculate the average of given scores and explain their answers using 5W1H1U questions. | Interactive board, SpeedUpScience blog and student notebooks | Apply mathematical concepts to practical situations. |
5W1H1U Questioning Approach
| Question Type | Average | Direct Unitary Method |
|---|---|---|
| What? | What is the average of 10, 20 and 30? | What is the cost of 5 pencils if one pencil costs ₹4? |
| Why? | Why do we divide the sum by the number of quantities? | Why do we find the value of one item first? |
| When? | When do we use average in daily life? | When can we use the direct unitary method? |
| Where? | Where can we find average scores or marks? | Where can we use this method while shopping? |
| Who? | Who can calculate the average score of a team? | Who might use this method to calculate the cost of several items? |
| How? | How do we calculate average? | How do we find the cost of 8 notebooks if 2 notebooks cost ₹30? |
| How much / How many? (U) | How much is the average of 12, 18 and 24? | How much will 6 items cost if one item costs ₹15? |
Short Classroom Activities
| Activity | Procedure | Learning Outcome |
|---|---|---|
| Average Detective | Display three or four numbers on the interactive board. Students calculate their average and explain the steps. | Understand and calculate average. |
| Score Challenge | Display sample quiz scores. Students calculate the average individually and compare their answers with a partner. | Develop accuracy and mental calculation skills. |
| Mini Shopping Activity | Display a price list. If one notebook costs ₹20, students calculate the cost of five notebooks using the direct unitary method. | Apply the unitary method to real-life situations. |
| Make Your Own Question | Students create a word problem on either topic, exchange it with a partner and solve it. | Develop creativity, reasoning and communication. |
