Model Equivalent Fractions with Fraction Strips
Model Equivalent Fractions with Fraction Strips is a Grade 3 math skill from Eureka Math using visual fraction strip models to demonstrate that different fractions can name the same amount. Equivalent fractions have the same value even though they use different numerators and denominators—for example 1/2 = 2/4. By aligning fraction strips of the same total length, students see that the shaded regions are identical in size. The equal sign between two fractions confirms equal value. This visual approach builds conceptual understanding before students apply rules for finding equivalent fractions.
Key Concepts
Equivalent fractions are different fractions that name the same amount of a whole. We use an equal sign (=) to show they have the same value, such as $\frac{1}{2} = \frac{2}{4}$.
Common Questions
What are equivalent fractions?
Equivalent fractions are different fractions that name the same amount of a whole. For example, 1/2 and 2/4 are equivalent because they represent the same-sized portion.
How do fraction strips show equivalent fractions?
Fraction strips are divided bars of the same total length. When two different fractions show identical shaded lengths, the strips demonstrate those fractions are equivalent.
How can 1/2 equal 2/4 if the numbers are different?
The numerator and denominator both changed by the same factor (multiplied by 2), so the value stayed the same. Doubling both parts of a fraction does not change what portion it represents.
Why do we use an equal sign between equivalent fractions?
The equal sign indicates the two fractions have the same value. Even though they look different, they represent identical amounts of the same-sized whole.
