Mathematics - Term 1 - Week 4

Multiplication can be thought of as repeated addition. For example, 4 multiplied by 3 (4 x 3) means adding 4 three times: 4 + 4 + 4 = 12. Division, on the other hand, is the process of splitting a number into equal parts. For instance, if we divide 12 by 4 (12 ÷ 4), we are asking how many groups of 4 can fit into 12, which equals 3. Understanding these concepts is crucial for solving more complex problems.

Let's solve 5 x 6. We can visualize this as 5 groups of 6. If we draw 5 circles and put 6 dots in each circle, we count all the dots: 6 + 6 + 6 + 6 + 6 = 30. Therefore, 5 x 6 = 30. Now, let's look at a division example: 30 ÷ 5. This asks how many groups of 5 are in 30. We can count: 5, 10, 15, 20, 25, 30, which gives us 6 groups. So, 30 ÷ 5 = 6.

Now, let's work on some problems together. First, calculate 7 x 4. Think of it as 7 groups of 4. How many do we have in total? (Students will respond.) Next, let's try 28 ÷ 4. How many groups of 4 fit into 28? (Students will respond.) After each problem, we will discuss the strategies used and any mistakes made.

Now it's your turn to solve some problems on your own. Complete the following: 8 x 3, 45 ÷ 5, 6 x 9, and 36 ÷ 6. Show your working clearly. After you finish, exchange your work with a partner and check each other's answers. Discuss any mistakes and how to correct them.
