Mathematics - Term 2 - Week 1

Addition is the process of combining two or more numbers to find a total, while subtraction is the process of taking one number away from another. For example, if you have 3 apples and you get 2 more, you can add them together to find out you have 5 apples. Conversely, if you have 5 apples and give away 2, you subtract to find you have 3 apples left. Visual models like number lines or counters can help us see these operations clearly.

Let's solve the problem: 4 + 3. We can use counters to represent this. Start with 4 counters, then add 3 more. Count all the counters together: 1, 2, 3, 4, 5, 6, 7. So, 4 + 3 = 7. Now, let's look at a subtraction example: 7 - 2. Start with 7 counters and take away 2. Count the remaining counters: 1, 2, 3, 4, 5. So, 7 - 2 = 5.

Now, let's practice together. I will give you a problem: 5 + 4. Use your counters or draw dots to represent the numbers. Count how many you have in total. After that, let's try a subtraction problem: 9 - 3. Again, use your counters or draw to visualize the problem. Remember to show your working clearly so we can discuss your methods.

Now it's your turn! Solve the following problems on your own: 6 + 2, 10 - 5, 3 + 7, and 8 - 4. Make sure to show your working for each problem. Once you finish, check your answers with a partner and discuss any mistakes you might have made. Remember, it's okay to make mistakes as long as we learn from them!
