Goals
1. Apply multiplication and division correctly.
2. Recognise and understand the components of multiplication and division.
3. Develop a logical approach to solving mathematical problems.
4. Build confidence in using basic maths in everyday situations.
Contextualization
Multiplication and division are essential skills that we often use in our daily lives without even realising it. Whether it’s figuring out how much flour to buy for a batch of koeksisters, splitting the bill at a braai with mates, or comparing prices at the shops, these operations are part of our routine. Grasping how they work helps us make more informed choices. For instance, in construction, multiplication can help determine how many bricks are needed for a wall, while division can show how much of a material is needed per square metre.

To Remember!
Components of Multiplication
Multiplication involves two numbers, where one number is added to itself several times based on the value of another. The main elements of multiplication are the multiplicand, the multiplier, and the product.
-
Multiplicand: The number being multiplied.
-
Multiplier: The number by which the multiplicand is multiplied.
-
Product: The result of multiplying the two numbers.
Components of Division
Division is a mathematical operation where a number is split into equal parts. The main components include the dividend, the divisor, the quotient, and the remainder.
-
Dividend: The number being divided.
-
Divisor: The number by which the dividend is divided.
-
Quotient: The outcome of dividing the dividend by the divisor.
-
Remainder: The part of the dividend that isn't completely divisible by the divisor.
Practical Applications of Operations
Multiplication and division have numerous applications in everyday life and professional settings. Understanding how to apply these concepts is key to solving real-world problems effectively.
-
Engineering: Used to calculate necessary materials and to size structures.
-
Commerce: Important for working out discounts, managing stock, and calculating profits.
-
Finance: Used to estimate profits, calculate interest, and assess investments.
Practical Applications
-
Calculating how many bags of cement you need for a building project.

Practical Challenge: Planning a Party
To reinforce your understanding of multiplication and division, you will plan a party using these math skills.
Instructions
-
Imagine you're throwing a party for 20 people.
-
Calculate how much food and drink you'll need. For instance, if every guest eats 3 slices of pizza and drinks 2 cups of soda, how many slices and cups will be required altogether?
-
Use multiplication to work out the total cost of the food and drinks. Assume each slice of pizza costs R20 and each cup of soda costs R15.
-
Divide the total cost by the number of guests to figure out how much each person should chip in.
-
Present your calculations and explain how you arrived at your answers.
