This week, we are going to explore two very important things: time and money! Understanding time helps us know when to be ready for school, when it's time for lunch, and even when our favourite TV show is on. In South Africa, knowing about days and weeks helps us plan for weekends, holidays like Heritage Day, and even when we need to go to the clinic for our check-ups. Learning about money, specifically coins, is also super important because it helps us buy sweets at the corner shop, contribute to stokvels later in life, or even save up for a special toy. We will learn how to identify different coins and understand that money is used to buy things we need and want.
Days of the Week: There are seven days in a week.
They always come in the same order: Monday Tuesday Wednesday Thursday Friday Saturday Sunday Think of the saying: "Mighty Teachers Wade Through Foul Stinky Swamps." Each word starts with the first letter of each day of the week.
Weeks: A week is a group of seven days. After Sunday, we start a new week with Monday again! Understanding weeks helps us know how long until our birthday, or when school holidays start. 1 week = 7 days.
Example: If today is Monday, then in one week it will be Monday again!
South African Coins: In South Africa, we use coins to buy things.
Let's look at some important coins: 10c (Ten Cents): A small, bronze-colored coin. It has a picture of honeybees on it. 20c (Twenty Cents): A slightly larger, bronze-colored coin. It shows a protea flower. 50c (Fifty Cents): A silver-colored coin, bigger than the 20c coin. It has a picture of a Strelitzia flower.
R1 (One Rand): A larger, silver-colored coin. It features a springbok.
R2 (Two Rand): A gold-colored coin with a silver centre. It displays a kudu.
R5 (Five Rand): A larger, gold-colored coin with a silver centre. It showcases a wildebeest. Important
Note: When we write the amount of money, we use 'c' for cents and 'R' for Rand. So, 10 cents is written as 10c, and 1 Rand is written as R
1. Counting Coins of the Same Type: When you have a group of the same type of coins, you can count them to see how much money you have.
Example: If you have three 10c coins, you count 10c, 20c, 30c. You have 30c in total.
Simple Word Problems: We can use what we know about coins to solve problems about buying things.
Example: A sweet costs 50c. You have one 50c coin. Can you buy the sweet? Yes, because you have exactly enough money! Guided Practice (With Solutions)
Question 1: What day comes after Wednesday?
Solution: Thursday. Wednesday, Thursday, Friday are in order.
Question 2: How many days are there in one week?
Solution: 7 days.
Remember the days of the week: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday. There are seven of them.
Question 3: You have two 10c coins. How much money do you have in total?
Solution: 20c. 10c + 10c = 20c. We are adding the value of each coin to get the total amount.
Question 4: Lerato wants to buy a lollipop that costs R
1. She has a R1 coin. Can she buy the lollipop?
Solution: Yes. She has exactly the same amount of money as the lollipop costs.
Question 5: Name three South African coins.
Solution: R1, R2, 50c. Many other answers are possible - 10c, 20c, R5, for instance. Independent Practice (Questions Only) What day comes before Saturday? If today is Tuesday, what day will it be tomorrow? How many weeks are there in 14 days?
Identify each of these coins: [Insert Pictures of R5, 20c, R1, and 50c]. Write the amount next to each coin. You have four 10c coins. How much money do you have in total? David has one 50c coin and his friend gave him another 50c coin. How much money does David have now? A small packet of chips costs R
2. You have a R2 coin. Can you buy the chips? Sarah wants to buy an apple that costs R
5. She has a R2 coin and a R1 coin. Does she have enough money? Why or why not? List the days of the week in order, starting from Sunday. How many days are there in two weeks?
