Entry Behaviour: Students should have prior knowledge of counting numbers from 1 to 40 and be familiar with basic numbers like 41, 42, etc.

Behavioural Objectives: By the end of this lesson, students should be able to:

1. Count numbers from 41 to 50 accurately.
2. Compare numbers using the < (less than), > (greater than), and = (equal to) signs.
3. Order numbers from smallest to largest.

Instructional Procedure:

Hello, Primary 1 pupils! Today, we’re going to learn how to count and identify numbers or objects from 41 to 50. 📚🔢

Let’s start with 41. It’s made of 4️⃣0️⃣ and 1️⃣. When you add 1️⃣ to 4️⃣0️⃣, you get 4️⃣1️⃣.

Now, let’s count together: 41, 42, 43, 44, 45, 46, 47, 48, 49, 50! 🎉

These are our numbers from 41 to 50. You can also count objects like toys, candies, or pencils using these numbers. 🍭🚗✏️

Practice counting, and you’ll become super good at it! 😄👍

Content Presentation:

Let’s begin with 41. It’s like 4️⃣0️⃣ plus 1️⃣. So, 41 is four tens and one. 🤗

Now, we’ll count: 41, 42, 43, 44, 45, 46, 47, 48, 49, 50! 🎈🎉

These are the numbers from 41 to 50. You can use these to count toys, candies, or even your friends in a game! 🍭🧸👭

Keep practicing, and you’ll become great at counting! 👏😊

Let’s start with 41. It looks like this: 4️⃣1️⃣. It’s a 4 and a 1 together. ✍️

Now, here are all the numbers: 41, 42, 43, 44, 45, 46, 47, 48, 49, 50! 🎉

See? You can write them just like that. Keep practicing, and you’ll get even better! 🌟😃

Here are the numbers from 41 to 50 written in words:

41 – Forty-one

42 – Forty-two

43 – Forty-three

44 – Forty-four

45 – Forty-five

46 – Forty-six

47 – Forty-seven

48 – Forty-eight

49 – Forty-nine

50 – Fifty

Comparing Numbers Using less than, greater than and equal to 

Hello, Primary 1 students! Today, we’ll learn to compare numbers using signs like < (less than), > (greater than), and = (equal to). 🧮🔍

Let’s see how it works:

1. < (Less Than) – It’s like a hungry alligator. It eats the bigger number. For example, 3 < 5 means 3 is smaller than 5. 🐊

2. (Greater Than) – It’s like a big arrow pointing to the bigger number. For example, 7 > 4 means 7 is bigger than 4. ➡️

3. = (Equal To) – It’s like a balance scale. Both sides are the same. For example, 2 + 3 = 5 means 2 plus 3 is equal to 5. ⚖️

Now, let’s practice:

• 6 < 8 (Yes, 6 is smaller than 8)
• 9 > 5 (Yes, 9 is bigger than 5)
• 4 + 1 = 3 + 2 (No, they are not equal)

Great job, little mathematicians! Keep practicing, and you’ll become experts at comparing numbers. 🌟👏

Counting in 2s

Here are the numbers counting by 2s from 1 to 20:

1, 3, 5, 7, 9, 11, 13, 15, 17, 19

Keep going, and you’ll see the pattern of skipping one number each time you count by 2s! 👍🔢

Step 1: Introduction (5 minutes)

• Greet the students and review counting from 1 to 40.
• Explain that today we’ll learn to count from 41 to 50.
• Show number cards from 41 to 50 to familiarize students with these numbers.

Step 2: Counting from 41 to 50 (10 minutes)

• Use flashcards to display numbers and have students repeat after you.
• Encourage students to count aloud as you go through the numbers multiple times.
• Use pictures of objects to relate numbers to real-life examples.

Step 3: Comparing Numbers (15 minutes)

• Introduce the < (less than), > (greater than), and = (equal to) signs.
• Explain that < means smaller, > means bigger, and = means equal.
• Use examples on the whiteboard like 6 < 8 and ask students if it’s true.
• Have students practice comparing numbers in pairs.

Summary / Conclusion (5 minutes)

• Summarize the lesson by recapping what they’ve learned: counting from 41 to 50 and comparing numbers.
• Ask students if they have any questions.
