Mathematics - Term 3 - Week 7

Number sense is the ability to understand and work with numbers. It involves recognizing numbers, understanding their values, and being able to manipulate them in various ways. In this lesson, we will explore how numbers can be represented visually using objects, drawings, and number lines. This will help us see the relationships between numbers and improve our counting skills.

Let's look at the number 7. We can represent 7 using objects like blocks. If we have 7 blocks, we can group them in different ways, such as 5 blocks in one group and 2 blocks in another. This shows that 5 + 2 = 7. We can also draw 7 circles to visualize the number. This helps us understand that numbers can be broken down into smaller parts.

Now, let's have a number talk! I will show you the number 10 using a number line. Can anyone tell me how many numbers are before 10? (Pause for responses.) Great! There are 9 numbers before 10. Now, let’s think about how we can make 10 using addition. Who can give me two numbers that add up to 10? (Encourage students to share their ideas, such as 6 + 4 or 5 + 5.)

Now it's your turn to solve some problems on your own! Here are a few questions: 1. What is 3 + 4? 2. If you have 5 apples and you buy 2 more, how many do you have in total? Write down your answers and show your working. Remember to check your work and see if you can find any mistakes!
