Fraction strips show the different ways fractions can be broken into equal parts.

• A. Bar diagram
• B. Base-10 blocks
• C. Fraction strips
• D. Attribute blocks

Answer: (C)

Fraction strips are designed to visualize how a whole can be divided into equal parts. A strip is drawn or laminated with the whole length divided into equal segments, so you can shade 1 of 2 parts, 2 of 3 parts, 3 of 4 parts, and so on. This makes it easy to see how fractions relate to each other, compare their sizes, and recognize equivalent fractions by using strips of the same total length with different numbers of parts. The continuous length of the strip keeps the parts neatly in line, which directly shows the idea of partitioning a whole into equal pieces. While a bar diagram can represent fractions, the strip format most closely and clearly demonstrates breaking a whole into equal parts, making it the best fit. Base-10 blocks model place value and decimals, and attribute blocks focus on attributes rather than fractional parts.
