Definition and Explanation

  1. Counting Numbers 1-70:
    Counting means naming numbers in sequence from 1 to 70.
  2. Writing Numbers 1-70:
    Writing involves forming the correct digits for each number.
  3. Ordering Numbers (21-50):
    Arranging numbers in ascending or descending order, e.g., 21, 22, 23.
  4. Addition of Two 1-Digit Numbers:
    Adding two numbers gives a total sum, e.g., 2 + 3 = 5.
  5. Value of Zero in Addition:
    Zero added to any number leaves the number unchanged, e.g., 6 + 0 = 6.

Examples

  1. Count numbers from 1 to 70 aloud.
  2. Write numbers 21 to 50 in order.
  3. Arrange: 35, 33, 37, 34 (Answer: 33, 34, 35, 37).
  4. Solve: 3 + 5 = 8.
  5. Zero example: 7 + 0 = 7.
