Counting Skill:

1. Identifying Numbers:
   • Let’s learn to recognize numbers from 701 to 720. For example, 701, 702, 703…
   • 🎉 Example: What comes after 709?
2. Ordering Numbers:
   • Practice putting numbers in order from 1 to 720. This helps us understand the sequence.
   • 🧩 Example: Arrange these numbers in order: 715, 702, 720, 701.
3. Counting Numbers:
   • We’ll count from 1 to 720. Counting helps us understand the value of each number.
   • 🏰 Example: Count by tens up to 70. What comes after 50?
4. Writing Numbers:

Remember, practice makes perfect! 🌟 Let’s work together to become masters of numbers and addition. 🌈

Counting Skill:

1. Identifying Numbers:
   • Example: What comes after 709?
     • Explanation: After 709, we add 1 to get 710.
2. Ordering Numbers:
   • Example: Arrange these numbers in order: 715, 702, 720, 701.
     • Explanation: When we order them, it becomes 701, 702, 715, 720.
3. Counting Numbers:
   • Example: Count by tens up to 70. What comes after 50?
     • Explanation: Counting by tens: 50, 60, 70. The next number is 60.
4. Writing Numbers:
   • Example: Write the number 520 in words.
     • Explanation: 520 in words is “five hundred twenty.”

Addition Skill:

5. Adding Numbers:
   • Example: Add 345 + 278 using the partial sum method.
     • Explanation: Add the digits in each place value separately (5 + 8 = 13, carry over 1; 4 + 7 + 1 = 12; 3 + 2 = 5). So, 345 + 278 = 623.
6. Addition Story:
   • Example: Sarah had 356 candies. She got 243 more. How many candies does she have now?
     • Explanation: Sarah has 356 candies. She got 243 more, so we add: 356 + 243 = 599 candies.

Skip Counting:

7. By 6s:
   • Example: Skip count by 6 up to 54. What’s the next number?
     • Explanation: 6, 12, 18, 24, 30, 36, 42, 48, 54. The next number is 60.
8. By 7s:
   • Example: Skip count by 7 up to 35. What’s the next number?
     • Explanation: 7, 14, 21, 28, 35. The next number is 42.
9. By 9s:
   • Example: Skip count by 9 up to 45. What’s the next number?
     • Explanation: 9, 18, 27, 36, 45. The next number is 54.
10. By 10s:
    • Example: Skip count by 10 up to 70. What’s the next number?
      • Explanation: 10, 20, 30, 40, 50, 60, 70. The next number is 80.
