Durasi: 10 - 15 minutes

This phase aims to introduce learners to the concept of equivalent fractions, providing a solid grounding for understanding how different fractions can represent the same amount. It's crucial for learners to grasp that, despite differing denominators, some fractions can be equivalent and that each group of equivalent fractions has a simplified, or irreducible, form.

Tujuan Utama:

1. Identify equivalent fractions using whole numbers, even when they have different denominators.

2. Recognise that among all equivalent fractions, there is only one that is in its simplest form.

Pendahuluan

Durasi: 10 - 15 minutes

This phase aims to lay the groundwork for understanding equivalent fractions, highlighting that different fractions can represent the same quantity. It’s essential that learners understand that, despite having different denominators, some fractions are equivalent and that each group has a simplified, irreducible fraction.

Tahukah kamu?

Did you know that equivalent fractions pop up often in cooking? For example, half a cup of sugar (1/2) is identical to two quarters of a cup (2/4) or four eighths of a cup (4/8). This flexibility allows cooks to easily tweak ingredient amounts without altering the final dish. Equivalent fractions are also key in fields like building, engineering, and finance where precise calculations matter.

Kontekstualisasi

To kick off the lesson on equivalent fractions, it’s vital to link the topic to the learners’ daily experiences. Ask them if they’ve ever shared a pizza or cake with friends. Explain that when you cut the pizza into different numbers of slices, each slice represents a fraction of the whole. For instance, if a pizza is cut into 4 equal slices, each slice is 1/4 of the pizza. If the same pizza is cut into 8 slices, each slice represents 1/8 of the pizza. Even with different denominators, both fractions represent the same quantity of pizza when compared correctly.

This phase deepens learners' understanding of equivalent fractions through detailed explanations and hands-on examples. It's important for them to learn how to identify, simplify, and visualise equivalent fractions while grasping their applications in real life. This phase also includes guided practice, allowing learners to apply what they've learned in specific exercises.

Topik Relevan

1. Concept of Equivalent Fractions: Explain what equivalent fractions are. Use visual examples, like dividing a pizza into different numbers of slices, to illustrate that 1/2, 2/4, and 4/8 represent the same quantity.

2. Method of Simplifying Fractions: Teach how to simplify fractions. Show how to find the greatest common divisor (GCD) to simplify fractions into their irreducible form. For example, simplifying 4/8 to 1/2.

3. Identification of Equivalent Fractions: Instruct how to identify equivalent fractions by multiplying or dividing the numerator and denominator by the same number, using relevant examples.

4. Visualisation of Equivalent Fractions: Use charts and diagrams, like fraction bars or pie charts, to help learners visualise equivalent fractions.

5. Practical Applications: Share practical examples where equivalent fractions are utilised, like in cooking recipes and construction measurements, reinforcing the relevance of the concept in everyday life.

1. 📝 What is the equivalent fraction of 2/3 if you multiply the numerator and denominator by 2? 2. Explain that to find an equivalent fraction, you just multiply both the numerator and the denominator by the same number. So here, multiplying by 2 gives: (2 x 2)/(3 x 2) = 4/6. Hence, the equivalent fraction to 2/3 is 4/6. 3. 📝 Simplify the fraction 6/9 to its irreducible form. 4. To simplify a fraction, find the greatest common divisor (GCD) between the numerator and the denominator. The GCD of 6 and 9 is 3. Dividing both by the GCD gives: 6 ÷ 3 / 9 ÷ 3 = 2/3. Thus, the simplified fraction of 6/9 is 2/3. 5. 📝 List two fractions equivalent to 3/4. 6. To find equivalent fractions, simply multiply or divide the numerator and denominator by the same number. For instance, multiplying by 2: (3 x 2)/(4 x 2) = 6/8. Multiplying by 3: (3 x 3)/(4 x 3) = 9/12. Therefore, two equivalent fractions to 3/4 are 6/8 and 9/12.
