Introduction

Higher order thinking is a critical component of mathematics education, as it enables students to analyze and evaluate complex mathematical concepts. One of the fundamental concepts in mathematics is equivalent fractions, which are fractions that have the same value despite having different numerators and denominators. In this article, we will explore the concept of equivalent fractions and use area models to demonstrate whether Fred's statement that $\frac{1}{2}$ and $\frac{7}{8}$ are equivalent fractions is correct.

What are Equivalent Fractions?

Equivalent fractions are fractions that have the same value, but differ in their numerators and denominators. For example, $\frac{1}{2}$ and $\frac{2}{4}$ are equivalent fractions because they both represent the same value, which is half of a whole. Similarly, $\frac{3}{6}$ and $\frac{1}{2}$ are also equivalent fractions.

Area Models for Equivalent Fractions

Area models are a visual representation of fractions, where the numerator represents the number of equal parts and the denominator represents the total number of parts. By using area models, we can easily compare and contrast different fractions to determine if they are equivalent.

Area Model for $\frac{1}{2}$

To create an area model for $\frac{1}{2}$ , we can draw a rectangle with a total area of 1 unit. We can then divide the rectangle into two equal parts, with one part representing $\frac{1}{2}$ of the total area.

|  1/2          |

Area Model for $\frac{7}{8}$

To create an area model for $\frac{7}{8}$ , we can draw a rectangle with a total area of 1 unit. We can then divide the rectangle into 8 equal parts, with 7 parts representing $\frac{7}{8}$ of the total area.

+---------------+
|  7/8          |

Comparing the Area Models

By comparing the area models for $\frac{1}{2}$ and $\frac{7}{8}$ , we can see that they are not equivalent fractions. The area model for $\frac{1}{2}$ represents half of a whole, while the area model for $\frac{7}{8}$ represents $\frac{7}{8}$ of a whole. This means that Fred's statement that $\frac{1}{2}$ and $\frac{7}{8}$ are equivalent fractions is incorrect.

Two Equivalent Fractions

However, there are two fractions that are equivalent to $\frac{1}{2}$ , which are $\frac{2}{4}$ and $\frac{3}{6}$ . These fractions have the same value as $\frac{1}{2}$ , but differ in their numerators and denominators.

Conclusion

In conclusion, higher order thinking is a critical component of mathematics education, as it enables students to analyze and evaluate complex mathematical concepts. By using area models, we can easily compare and contrast different fractions to determine if they are equivalent. In this article, we explored the concept of equivalent fractions and used area models to demonstrate whether Fred's statement that $\frac{1}{2}$ and $\frac{7}{8}$ are equivalent fractions is correct. We found that the statement is incorrect, but identified two equivalent fractions to $\frac{1}{2}$ , which are $\frac{2}{4}$ and $\frac{3}{6}$ .

Real-World Applications

Equivalent fractions have numerous real-world applications, such as:

Cooking: When cooking, equivalent fractions can be used to measure ingredients. For example, if a recipe calls for $\frac{1}{2}$ cup of sugar, but you only have $\frac{3}{6}$ cup measuring cups, you can use the equivalent fraction $\frac{3}{6}$ to measure the correct amount of sugar.
Building: When building, equivalent fractions can be used to calculate the area of a room. For example, if a room has an area of $\frac{1}{2}$ square meters, but you want to calculate the area in square feet, you can use the equivalent fraction $\frac{2}{4}$ to convert the area.
Science: When conducting scientific experiments, equivalent fractions can be used to calculate the volume of a liquid. For example, if a beaker has a volume of $\frac{1}{2}$ liter, but you want to calculate the volume in milliliters, you can use the equivalent fraction $\frac{3}{6}$ to convert the volume.
