Performance objectives

• Count forwards and backwards between 0 and 20.
• Order numbers from smallest to largest and largest to smallest.
• Represent numbers using objects, drawings, and symbols.
• Find the number that is one more or one less.
• Compare two groups using 'more than', 'less than', or 'equal to'.

Lesson summary

This week, we are diving deeper into the world of numbers from 0 to 20! Learning to count, order, and represent these numbers is super important because numbers are everywhere around us in South Africa. Think about when you buy sweets at the spaza shop – you need to count how many you are buying and how much money to give the shop owner. If you're sharing toys with your friends, you need to count to make sure everyone gets a fair share. Even when playing games like Diketo, you need to keep score using numbers! This week, we'll build a strong foundation for understanding these essential numbers.

Lesson notes

Counting: Counting means saying the numbers in order. We can count forwards (1, 2, 3…) or backwards (20, 19, 18…). Use your fingers, toes, or anything else to help you! Let’s practice counting forwards:

Example: Count forwards from 5 to 12. 5, 6, 7, 8, 9, 10, 11, 12 Now let's count backwards:

Example: Count backwards from 18 to 9. 18, 17, 16, 15, 14, 13, 12, 11, 10, 9 Ordering: Ordering means putting numbers in the correct sequence, either from the smallest to the largest (ascending order) or from the largest to the smallest (descending order).

Example: Order the numbers 7, 15, 3, and 11 from smallest to largest.

Think: Which number is the smallest?

3. Which is the next smallest?

7. Then 11, and finally

5. Answer: 3, 7, 11, 15

Example: Order the numbers 20, 8, 12, and 5 from largest to smallest.

Think: Which number is the largest?

2

0. Next largest?

1

2. Then 8, and lastly

5. Answer: 20, 12, 8, 5 Representing: Representing numbers means showing what they mean using different things.

We can use: Concrete Objects: Beans, stones, counters, pencils, etc. If you have 13 beans, that's representing the number

1

3. Drawings: Drawing circles, squares, or any other pictures to represent the number. If you draw 9 stars, that's representing the number

9. Number Symbols: The actual written number (1, 2, 3, 4, etc.). Let’s look at some examples: Representing the number 6: Concrete Objects: 6 stones Drawings: Draw 6 circles (● ● ● ● ● ●)

Number Symbol: 6 Representing the number 14: Concrete Objects: 14 counters Drawings: Draw 14 squares (■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■)

Number Symbol: 14 One More Than/One Less Than: This means finding the number that comes right after or right before a given number. One more than 10 is 11 (because 11 comes right after 10 when counting). One less than 17 is 16 (because 16 comes right before 17 when counting). Comparing Quantities (More Than, Less Than, Equal To): This means looking at two groups of objects and deciding which group has more, which has less, or if they have the same amount.

Example: You have a group of 8 apples and a group of 5 oranges. 8 is more than 5. 5 is less than

8. Example: You have 12 marbles and your friend has 12 marbles. 12 is equal to

2. Guided Practice (With Solutions)

Question 1: Count forwards from 8 to

1

5. Write down the numbers you say.

Solution: 8, 9, 10, 11, 12, 13, 14,

1

5. We start at 8 and keep adding one until we reach

1

5. Question 2: Order these numbers from largest to smallest: 4, 16, 9,

1. Solution: 16, 9, 4,

1. We look for the biggest number first (16), then the next biggest (9), and so on.

Question 3: Represent the number 11 using drawings. Draw circles.

Solution: ● ● ● ● ● ● ● ● ● ● ● (11 circles). We draw the same number of circles as the number we are representing.

Question 4: What number is one more than 19?

Solution:

2

0. One more than 19 is the number that comes right after it when we count.

Question 5: You have a bag with 7 sweets and your friend has a bag with 13 sweets. Who has more sweets?

Solution: Your friend has more sweets. 13 is more than

7. Independent Practice (Questions Only) Count backwards from 16 to

7. Write down the numbers you say. Order these numbers from smallest to largest: 18, 2, 13,

6. Represent the number 9 using concrete objects. (List three different objects you could use). Draw a picture representing the number 15 (use any shapes you like). What number is one less than 12? What number is one more than 8? You have a plate with 10 biscuits and your brother eats

4. How many biscuits are left? (Hint: This requires subtracting, building on the concept of "less than"). Sipho has 5 toy cars. Thandi has 5 toy cars. Do they have the same number of toy cars? Which is greater, 14 or 6? Arrange the following numbers in descending order: 3, 11, 17, 5, 0.
