Which example demonstrates a basic notation activity for young learners?

• A. Using letters to label vertices of a geometric figure.
• B. Counting numbers without symbols.
• C. Solving equations without any symbols.
• D. Describing shapes by color only.

Answer: (A)

Using letters to label vertices demonstrates how symbols can stand for parts of a figure, which is a basic notation activity for young learners. This helps children move from describing shapes with words to using symbols to reference specific parts, building foundational skills in symbolic reasoning that support later geometry work. The other options don’t focus on using symbols to represent mathematical objects or relationships—counting without symbols, solving equations without symbols, or describing shapes by color alone all emphasize description or purely numerical action rather than introducing symbolic notation.
