Mathematics - Term 3 - Week 9

Addition is the process of combining two or more numbers to find a total. For example, if you have 2 apples and you get 3 more, you can add them together to find out you have 5 apples in total. Subtraction, on the other hand, is taking away a number from another. If you have 5 apples and you give away 2, you subtract 2 from 5 to find out you have 3 apples left. We can use visual aids like counters or drawings to help us understand these concepts better.

Let's look at the problem: 4 + 3. We can use counters to visualize 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 write it down: 4 + 3 = 7.

Now, let's try a subtraction problem: 6 - 2. We can start with 6 counters. If we take away 2 counters, we count the remaining ones: 1, 2, 3, 4. So, 6 - 2 = 4. We can write this as: 6 - 2 = 4.

Let's practice together! What is 5 + 2? Use your fingers or counters to help you. Count 5 fingers, then add 2 more. How many do you have in total? Share your answer with a partner. Remember to write it down as 5 + 2 = __.

Now, let's try a subtraction problem together. What is 8 - 3? Start with 8 counters and take away 3. Count how many are left. Share your answer with your partner and write it down as 8 - 3 = __.

Now it's your turn! Solve the following problems on your own: 1) 3 + 4 = __ 2) 7 - 5 = __ 3) 2 + 6 = __ 4) 9 - 1 = __. Remember to show your working by drawing counters or using your fingers if needed.
