Definition and Explanation:

  1. Counting Numbers: Counting means identifying numbers in sequential order.
  2. Writing Numbers: Writing numerals helps represent quantities.
  3. Order of Magnitude: Arranging numbers in ascending order (small to large) and descending order (large to small).
  4. Skip Counting: Counting forward or backward by skipping a set number of steps, e.g., 2s, 10s.

Examples:

  1. Count numbers from 51 to 100 aloud.
  2. Write numbers 51-60 on the board.
  3. Arrange 55, 63, 72, 81, 90 in ascending order: 55, 63, 72, 81, 90.
  4. Skip count in 2s: 52, 54, 56, 58, 60…
  5. Backward counting from 100: 100, 99, 98…
