### Day 1: Introduction to Measurement
**Objectives:**
- Understand different units of measurement for time, length, mass, and volume.
- Introduction to standard and metric system.
**Activities:**
1. **Warm-Up**: Start with a discussion about why measurement is important. Where do they see or use measurement in daily life? (e.g., baking, timekeeping, weighing fruits, buying fabric).
2. **Direct Instruction**:
- Discuss different units of measurement for time (second, minute, hour).
- Introduce length (millimeter, centimeter, meter, inch, foot, yard).
- Talk about mass (gram, kilogram, ounce, pound).
- Explain volume (milliliter, liter, cup, pint, quart, gallon).
3. **Guided Practice**:
- Show real examples/items and measure them.
- Use rulers to measure objects around the classroom in centimeters and inches.
4. **Independent Practice**:
- Pass out a worksheet with mixed problems on identifying units for different measurements and simple conversion problems.
5. **Closing**:
- Recap the day's learning and ask students to share one new thing they learned.
- Assign a home activity to record the time they spend on different activities (to be used Day 2).
### Day 2: Measuring Time
**Objectives:**
- Read and interpret analog and digital clocks.
- Understand units of time and convert between them.
**Activities:**
1. **Warm-Up**: Discuss home activity from Day 1. Share how much time was spent on different activities.
2. **Direct Instruction**:
- Review the concept of seconds, minutes, hours, days, weeks.
- Practice reading analog and digital clocks.
3. **Guided Practice**:
- Use interactive clock tools (physical clocks or apps) to set and read specific times.
- Solve problems involving elapsed time.
4. **Independent Practice**:
- Worksheet on reading clocks and calculating elapsed time.
5. **Closing**:
- Recap different units of time and conversions.
- Question and answer session to clarify doubts.
### Day 3: Measuring Length
**Objectives:**
- Measure lengths using both standard (inches, feet, yards) and metric units (millimeters, centimeters, meters).
- Convert between different units of length.
**Activities:**
1. **Warm-Up**: Quick review of units of length and their uses.
2. **Direct Instruction**:
- Demonstrate using rulers and tape measures.
- Discuss and demonstrate conversion (for example, how many centimeters in a meter).
3. **Guided Practice**:
- Measure objects around the classroom/school in different units.
- Practice converting measurements (e.g., converting inches to feet).
4. **Independent Practice**:
- Worksheet on measuring lengths and converting units.
5. **Closing**:
- Recap the importance of choosing the right unit.
- Discuss where they might need to convert measurements in real life.
### Day 4: Measuring Mass and Volume
**Objectives:**
- Measure mass using grams and kilograms.
- Measure volume using milliliters and liters.
- Convert between different units of mass and volume.
**Activities:**
1. **Warm-Up**: Discuss items they think are heavy vs. light and hold different quantities of liquids.
2. **Direct Instruction**:
- Use scales to measure different objects.
- Demonstrate measuring liquids with different-sized cups/spoons.
- Discuss conversions (e.g., grams to kilograms, milliliters to liters).
3. **Guided Practice**:
- Hands-on activity: students measure different items and record their weights/volumes.
- Practice converting between units.
4. **Independent Practice**:
- Worksheet on mass and volume measurements and conversions.
5. **Closing**:
- Recap the day’s learning and discuss practical applications.
- Assign a simple home practice like measuring ingredients for a recipe.
### Day 5: Applying Measurement in Real-World Problems
**Objectives:**
- Solve real-world problems involving measurements and conversions.
**Activities:**
1. **Warm-Up**: Review the week’s learning on time, length, mass, and volume.
2. **Direct Instruction**:
- Explain how all these measurements come together in real-world contexts (e.g., cooking, construction).
3. **Guided Practice**:
- Group activity: Kids create a project that involves multiple measurements (e.g., planning a small garden plot, designing a simple recipe).
4. **Independent Practice**:
- Each student solves a set of word problems that involve different kinds of measurements and conversions.
5. **Closing**:
- Recap the week’s learning, and each student shares one way they will use measurement skills in their lives.
### Assessment:
- Daily worksheets.
- Observations during guided and independent practice.
- Final project presentation.
- Participation in discussions and activities.
### Extension Activity:
- Create a class measuring book where each student contributes a page about something they've measured and how they did it. This can include drawings, photos, and descriptions.
