#### Topic: Measurement + Gymnastics + Coding
---
#### Objectives:
1. Understand basic units of measurement (length, weight, time, etc.).
2. Perform basic gymnastic activities to apply measurement in a physical context.
3. Learn introductory coding concepts related to measurement and physical activities.

### **Lesson Structure:**
#### **1. Introduction (10 minutes)**
- **Greeting and Attendance:** Take attendance and welcome students.
- **Review Previous Lessons:** Briefly review the last week's topics.
- **Introduction to Today's Lesson:**
- Explain how measurement, physical activity, and coding are interconnected.
- State today’s objectives clearly.
#### **2. Measurement Basics (20 minutes)**
- **Units of Measurement:**
- Discuss units of measure (centimeters, meters, seconds, grams, kilograms).
- Use real-life objects to illustrate e.g., rulers, weighing scales, stopwatches.
- **Interactive Activity:**
- Students measure the length of their desks, height of classmates, and weight of common classroom objects.
- Record measurements in their notebooks.
#### **3. Gymnastics and Applied Measurement (30 minutes)**
- **Warm-Up Exercises:**
- Simple stretching exercises (5 minutes).
- **Measurement in Gymnastics:**
- Demonstrate how to measure jumps (distance jumped), balance (time held), and weights lifted (using lightweight objects).
- Use tape measures, stopwatches, and balance scales.
- **Practical Activity:**
- In pairs, students perform the activities (jumps, balance, weight lifts) and measure the outcomes.
- Record results and discuss observations (e.g., longer strides lead to higher jump measurements).
#### **4. Coding Concepts (20 minutes)**
- **Introduction to Coding:**
- Explain what coding is—simple instructions for a computer.
- Use visual coding programs appropriate for age group (e.g., Scratch Jr.).
- **Connect Coding to Measurement:**
- Simple coding activity: create a program that "measures" distance or counts time.
- Example: A sprite that moves a certain number of steps based on the inputs they recorded during the gymnastics activities.
- **Guided Activity:**
- Students, in small groups, use tablets/computers to input data from gymnastics activities into the coding program.
- Observe and modify outputs.
#### **5. Conclusion (10 minutes)**
- **Review and Recap:**
- Go through the main points of measurement, gymnastics, and coding activities.
- **Q&A Session:**
- Provide time for students to ask questions and clarify doubts.
- **Homework:**
- Measure objects around home and record findings.
- Try a simple physical activity and measure outcomes.
- Optional: Spend 15 minutes on a coding activity related to measurement (provide a link or app recommendation).
---
#### **Materials Needed:**
- Rulers, tape measures, stopwatches, balance scales, lightweight objects for weights.
- Tablets/computers with a visual coding program (e.g., Scratch Jr.).
- Measuring charts and papers for recording measurements.
- Projector/whiteboard for demonstration.
---
#### **Assessment:**
- Participation in interactive activities.
- Accuracy and completeness of recorded measurements.
- Engagement and collaboration during coding activity.
- Homework submission and quality.
---
#### **Differentiation:**
- **For Advanced Students:** Provide more complex coding challenges or encourage measurement of more difficult physical tasks.
- **For Beginners:** Offer additional guidance during coding and physical measurement activities. Simplify tasks and provide more direct support.
---
### **Reflection:**
- At the end of the class, reflect as a teacher on what went well and what could be improved. Note students’ engagement and understanding levels, and adjust future lessons accordingly.
