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 count accurately. In this lesson, we will explore how to count objects, recognize patterns in numbers, and understand the relationship between numbers. We will use visual aids like number lines and counters to help us visualize these concepts.

Let's count the apples together! If we have 3 apples on the table and I add 2 more, how many apples do we have in total? We can count them one by one: 1, 2, 3 (the original apples), 4 (the first added apple), and 5 (the second added apple). So, 3 + 2 = 5. We can also use a number line to show this addition visually.

Now, let's practice counting using counters. I will give each of you 5 counters. Count them out loud. Next, I will add 3 more counters to your pile. How many do you have now? Let's count together: 1, 2, 3, 4, 5 (the original), 6, 7, 8. So, 5 + 3 = 8. Remember to always count carefully and check your work!

Now it's your turn to solve some problems on your own. I will give you a worksheet with different counting problems. For example, if you have 4 birds and 3 more come to visit, how many birds do you have now? Write down your answer and show your working. After you finish, we will review the answers together and discuss any mistakes.
