Hello, Grade 2 pupil! Today, we’re going to learn how to count from 320 to 350 in a fun way. 🎉

Let’s start with 320. Can you see it? It’s like saying “three hundred twenty.” 🤓

Now, let’s count together: 320, 321, 322, 323, 324, 325, 326, 327, 328, 329, 330, 331, 332, 333, 334, 335, 336, 337, 338, 339, 340, 341, 342, 343, 344, 345, 346, 347, 348, 349, 350! 🎈

Great job! We counted from 320 to 350, one number at a time. Remember, counting helps us know the order of numbers, just like counting your favorite candies! 🍬

Now, you can try counting from 320 to 350 on your own. Have fun practicing! 🌟

Introduction (5 minutes):

• Begin by reviewing counting skills from 1 to 300 to prepare students for the new range of numbers.
• Explain that today, they will learn to count from 320 to 350 and compare these numbers.

Counting Practice (10 minutes):

• Show the number cards from 320 to 350 in sequence on the board.
• Have the students count aloud together as you point to each number on the cards.
• Encourage individual students to come to the board and point to the numbers in sequence.

Comparison Symbols (5 minutes):

• Introduce the less than (<), greater than (>), and equal to (=) symbols using flashcards.
• Explain the meanings of these symbols:
  • “<” means “less than.”
  • “>” means “greater than.”
  • “=” means “equal to.”
• Provide simple examples to illustrate each symbol’s use.

1. Less Than (<): This symbol looks like a “crocodile mouth” that eats the smaller number. 🐊

Example: 3 < 5 It means 3 is smaller than 5. The crocodile eats the smaller number, which is 3.

2. Greater Than (>): This symbol is like a “big open mouth” that likes to gobble up the bigger number. 😮

Example: 7 > 4 It means 7 is bigger than 4. The big mouth wants to eat the bigger number, which is 7.

3. Equal To (=): This symbol shows that both numbers are the same, like twins! 👯‍♂️

Example: 6 = 6 It means 6 is equal to 6. They are the same, just like twins who look alike.

Now, let’s try some fun examples:

• 4 __ 6 (Fill in the blank with <, >, or =) What do you think? Is 4 smaller, bigger, or equal to 6?
• 9 __ 9 Are they the same or different?
• 5 __ 2 Which number is bigger this time?

You’re doing great! These symbols help us compare numbers easily. Keep practicing, and you’ll become a math pro! 🌟🧮

Ordering Numbers Activity (10 minutes):

• Display a set of number cards on the board (e.g., 325, 340, 335, 330).
• Ask students to arrange the numbers in ascending order (smallest to largest) and use the “<” symbol to compare them.
• Discuss the correct order and comparison symbols as a class.

Teacher’s Activities (5 minutes):

• Write several pairs of numbers on the board (e.g., 322 < 328, 345 > 341, 327 = 327).
• Explain each comparison and ask students if the statements are true or false.
• Discuss the correct answers with the class.

Learners’ Activities (5 minutes):

• Encourage students to participate by verifying if the comparison statements are true or false.
• Explain their reasoning for each statement.

Worksheets Practice (5 minutes):

• Distribute worksheets with number sequences and comparison symbols.
• Ask students to complete the worksheets by filling in the correct symbols (<, >, or =) to compare numbers.

Conclusion (5 minutes):

• Recap the lesson by reviewing the counting skills from 320 to 350 and the use of comparison symbols.
• Emphasize the importance of understanding these symbols for ordering numbers correctly.

Homework:

• Assign homework exercises involving counting and comparing numbers using the symbols <, >, and =.
