Which numbers describe position or order in a list?

• A. Cardinal numbers
• B. Ordinal numbers
• C. Base-10 blocks
• D. Fraction strips

Answer: (B)

Ordinal numbers express position or order in a sequence, using terms like first, second, and third to show where something stands in a list. Cardinal numbers describe how many items there are (one, two, three), which is about quantity rather than position. Base-10 blocks are a place-value tool for building numbers, not for indicating order. Fraction strips help visualize fractions and parts of a whole, not the order of items in a sequence. So the choice that best describes position or order in a list is ordinal numbers.
