Exploring Numbers and Operations 📊

Writing Numbers in Words and Figures 📝

Example:

• “106” in words is “One hundred and six.”

• “58” has 5 Tens and 8 Units.

Basic Addition and Subtraction 🧮

Example:

• Subtracting: 18 – 3 = 15
• Adding: TU + 21 = 39 (Tens and Units)
• On a number line: Start at 8, move 3 back to get 5.

Counting Patterns and Fractions 🔄

Example:

• Counting by 2’s: 50, 52, 54, 56, 58…
• Fraction: Shaded part in a figure is 1/3.
• Number line subtraction: Start at 8, move 3 back to get 5.

Place Value and Number Identification 🔢

Example:

• Identify Tens and Units: 46 has 4 Tens and 6 Units.

Primary 1 students:

1. Write the following numbers in words:
   • 106: One hundred and six
   • 232: Two hundred and thirty-two
2. Subtract the following numbers:
   • 18 – 3 = 15
   • 20 – 6 = 14
3. Add the following numbers together:
   • TU
     • 21

     ---

     = 39

   • TU
     • 14

     ---

     = 36

4. Add the following together using a number line:
   • Start at 6, move 3 steps forward, reach 9.
5. Write the following numbers in figures:
   • Five hundred and thirty: 530
   • Three hundred and four: 304
   • Two hundred and twenty-one: 221
6. Count the following numbers in 2’s:
   • 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84
7. Subtract the following using a number line:
   • Start at 8, move 3 steps back, reach 5.
8. Write out the shaded fraction:
   • 1/3
9. Identify the following Tens and Units:
   • 46 = 4 Tens and 6 Units
   • 58 = 5 Tens and 8 Units

Remember, when subtracting using a number line, we start at a number and move backward for subtraction. When counting by 2’s, we skip count: 2, 4, 6, 8, and so on. Tens and Units help us understand the place value of numbers, where Tens are groups of ten and Units are single digits. Keep practicing and learning! 📚✏️
