Which tool is specifically used to show base-10 place value values?

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

Answer: (C)

Base-10 place value is shown most clearly with base-10 blocks, which come in units, rods, and flats. Ten of the ones form a ten, and ten of the tens form a hundred, so each piece represents a different power of 10. This setup makes it easy to see how digits in different positions contribute different amounts and how regrouping (like carrying) works in the base-10 system. Other tools illustrate different ideas: attribute blocks focus on categories like color or shape, fraction strips show parts of a whole, and a bar diagram can represent quantities or relationships without specifically modeling base-10 place value.
