2. Develop problem-solving skills involving the calculation of areas of simple geometric figures.

3. Apply self-awareness and self-control techniques when dealing with challenges and frustrations during the learning process.

Contextualization

Have you ever thought about how to calculate the amount of paint needed to paint a wall or the size of a rug to cover the floor of a room? Knowing how to calculate the area of basic geometric figures like triangles, squares, and rectangles can be very useful for these and many other everyday situations! Let's discover together how to do this in a fun way while also learning to manage our emotions during the process. 邏✨

Important Topics

Definition of Area

 Area is a measure of the amount of space within the boundaries of a two-dimensional figure. It is expressed in square units, such as cm², m², etc. Understanding this is fundamental for solving mathematical problems and applying that knowledge in practical everyday situations.

• Area is the amount of space within a two-dimensional figure.

• It is measured in square units, such as cm², m².

• Understanding area helps solve practical problems in daily life, such as measuring space for a new rug or calculating the amount of paint needed to paint a wall. ️

Area of a Square

 The formula for calculating the area of a square is very simple: side x side. If a square has sides of 5 cm, its area will be 5 cm x 5 cm = 25 cm². This formula is essential for solving problems involving measuring square surfaces.

• The formula is side x side.

• If a square has 5 cm sides, its area will be 25 cm².

• Knowing how to calculate the area of a square is useful in situations like determining the size of a tile or the amount of grass to cover a square field. 

Area of a Rectangle

 The area of a rectangle is calculated using the formula base x height. For example, if the base of a rectangle is 6 cm and the height is 4 cm, its area will be 24 cm². This is especially useful in everyday situations such as measuring the area of a table or a rectangular room.

• The formula is base x height.

• If the base is 6 cm and the height is 4 cm, the area will be 24 cm².

• Practical applications include measuring rectangular surfaces like tables or floors. 

Area of a Triangle

 The formula for calculating the area of a triangle is base x height / 2. For example, if the base of a triangle is 8 cm and the height is 5 cm, its area will be 20 cm². This formula is crucial for solving problems involving triangular figures, such as constructing roofs or creating art.

• The formula is base x height / 2.

• If the base is 8 cm and the height is 5 cm, the area will be 20 cm².

• Practical applications include building roofs and art projects. 

Key Terms

• Area: Measure of the space within a two-dimensional figure, expressed in square units.

• Square: Geometric figure with four equal sides and right angles.

• Rectangle: Geometric figure with two pairs of equal sides and right angles.

• Triangle: Geometric figure with three sides and three angles.

• Base: One of the sides of a geometric figure that serves as a reference for calculating the area.

• Height: The perpendicular distance between the base and the highest point of the geometric figure.

To Reflect

•  How did you feel when working in a group to calculate the area of different geometric figures? What were the challenges and how did you deal with them?

• 樂 Think of a situation in your daily life where you could apply the area calculation. How could that help solve a practical problem?

• ✍️ Reflect on a situation where you had to deal with frustration or difficulties while learning something new. What strategies did you use to regulate your emotions and keep learning?

Important Conclusions

• We learned the basic concept of area and how to calculate the area of triangles, squares, and rectangles.

• We developed problem-solving skills involving the calculation of areas of simple geometric figures.

• We practiced self-awareness and self-control when facing challenges and frustrations during the learning process.

Impact on Society

In everyday life, calculating the area of geometric figures is a practical and important skill. Whether it's to paint a wall, lay down a rug, or plan the arrangement of furniture in a room, understanding how to measure and calculate areas can greatly facilitate these tasks. This can also be especially useful in various professions that require these mathematical skills, such as architecture, engineering, and interior design.

In addition to practical applications, learning to calculate areas also helps us develop socio-emotional skills. When we work in groups to solve math problems, we practice cooperation, communication, and patience. We learn to deal with frustrations and challenges positively, strengthening our self-awareness and our ability to regulate emotions. These skills are valuable not only in school but in all areas of our lives.

Dealing with Emotions

Now, I suggest that you use the RULER method to reflect on your learning. First, recognize how you felt during the areas calculation activities. Were you confident? Frustrated? Next, understand why you felt that way. Was it due to the difficulty of the problem or collaboration with peers? Accurately label your emotions: it’s important to know the difference between feeling 'irritated' or 'challenged'. Express these emotions by writing about them or talking to someone you trust. Finally, regulate your emotions: if you feel frustrated, use deep breathing techniques or take a break. If you are proud, celebrate your success!

Study Tips

• Review the concepts of area weekly and practice solving new problems. This reinforces knowledge and helps solidify learning.

• Form study groups with friends. Discussing and solving problems together can make learning more fun and effective.

• Apply area calculations in everyday situations, such as measuring a room or calculating how many units of an object would fit on a surface. This makes learning more meaningful and connected to reality.
