This week, we begin our exciting journey into the world of numbers! The focus for Week 1 is building a strong foundation with numbers from 0 to
1
0. These numbers are the building blocks for all future mathematics. For Grade 1 learners in South Africa, understanding these basic numbers is essential for everyday life. We see numbers when we look at the price of sweets at the spaza shop, when we count our friends to play a game of 'bhathi' (cricket), or when we share slices of an orange. This week, we will move from just saying numbers to understanding what they represent, how to write them, and how to use them to solve simple, real-life problems.
A. Counting and Number Recognition (0-10) What is counting? Counting is how we find out 'how many' of something there are. When we count, we give one number to each object. This is called one-to-one correspondence. It's important not to skip any objects or count an object more than once.
Counting Forwards: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Counting Backwards: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 Writing Numbers: Each number has a symbol (how we write it) and a name (how we say it). | Symbol | Name | Example (with pictures of bottle tops) | |--------|-------|---------------------------------------| | 0 | Zero | (no bottle tops) | | 1 | One | 🔵 | | 2 | Two | 🔵 🔵 | | 3 | Three | 🔵 🔵 🔵 | | 4 | Four | 🔵 🔵 🔵 🔵 | | 5 | Five | 🔵 🔵 🔵 🔵 🔵 | | 6 | Six | 🔵 🔵 🔵 🔵 🔵 🔵 | | 7 | Seven | 🔵 🔵 🔵 🔵 🔵 🔵 🔵 | | 8 | Eight | 🔵 🔵 🔵 🔵 🔵 🔵 🔵 🔵 | | 9 | Nine | 🔵 🔵 🔵 🔵 🔵 🔵 🔵 🔵 🔵 | | 10 | Ten | 🔵 🔵 🔵 🔵 🔵 🔵 🔵 🔵 🔵 🔵 |
B. Ordering and Comparing Numbers Ordering Numbers: This means putting numbers in the right place, either from the smallest to the biggest or the biggest to the smallest. A number line helps us see the order.
Smallest to Greatest (Ascending): We start with the smallest number and go up. e.g., 2, 5,
8. Greatest to Smallest (Descending): We start with the biggest number and go down. e.g., 9, 6,
1. Comparing Numbers: We use special words to compare groups of objects: More than: The group with a bigger number of items. (e.g., 7 is more than 4)
Less than: The group with a smaller number of items. (e.g., 3 is less than 6)
Equal to: Both groups have the same number of items. (e.g., 5 is equal to 5)
Lindiwe has 4 sweets. Bongi has 6 sweets. Who has more?
Step 1: Count Lindiwe's sweets: 1, 2, 3,
4. Step 2: Count Bongi's sweets: 1, 2, 3, 4, 5,
6. Step 3: Compare the numbers. 6 is a bigger number than
4. So, Bongi has more sweets. Lindiwe has less sweets.
C. Simple Addition and Subtraction
Addition (+):
Addition means 'putting together' or 'joining' groups. The answer is called the sum or total. The '+' sign means we must add.
Worked
Example:
Sipho has 3 green marbles. His friend gives him 2 blue marbles. How many marbles does he have altogether?
Step 1 (Picture): Draw the two groups.
🟢🟢🟢 + 🔵🔵
Step 2 (Count): Count all the marbles together.
1, 2, 3, 4,
5. Step 3 (Number Sentence): Write it with numbers.
3 + 2 = 5
Answer: Sipho has 5 marbles altogether.
Subtraction (-):
Subtraction means 'taking away'. The answer tells us how many are left. The '-' sign means we must subtract.
