Mathematics - Term 4 - Week 5

Number sense is the ability to understand and work with numbers. It involves recognizing numbers, understanding their value, and being able to manipulate them in various ways. Today, we will explore how to count objects, recognize patterns, and understand the relationships between numbers. We will use visual aids like number lines and counters to help us see these concepts clearly.

Let's count the number of apples in a basket. If there are 3 red apples and 2 green apples, how many apples do we have in total? We can use addition to find the answer: 3 + 2 = 5. We can also represent this with counters: place 3 red counters and 2 green counters together to see that we have 5 counters in total. This shows how counting objects helps us understand addition.

Now, let's have a number talk! I will show you a number line from 0 to 10. Can anyone tell me what number comes after 4? (Pause for responses.) That's right, it's 5! What about before 3? (Pause for responses.) Correct, it's 2! This exercise helps us think about numbers and their order, which is an important part of number sense.

Now it's your turn to solve some problems on your own. Here are a few questions: 1) If you have 4 candies and your friend gives you 3 more, how many candies do you have now? 2) Count the number of stars in the picture and write down the total. Remember to show your working clearly! After you finish, we will review your answers together.
