Set Induction:
Start by singing a fun song on counting, addition, and subtraction, incorporating shapes and ordinal numbers. This can get the pupils excited and engaged right from the start. You can also use a number chart showing numerals 1-500 for visual aid.
Entry Behaviour:
Pupils are expected to know how to count numbers up to 100 from the first term. They should also have an understanding of basic addition and subtraction within 20.
Learning Resources and Materials:
- Flashcards
- Shells
- Crayons
- Chart of fractions
- Audio-visual resources (e.g., a number chart showing numerals 1-500, flashcards)
Building Background/Connection to Prior Knowledge:
The pupils should recall their previous knowledge of counting and basic arithmetic (addition and subtraction) from the first term. They should also have learned about shapes and fractions, which will be linked to the new topic of numbers and ordering.

Content:
1. Counting Numbers (1-450):
- Counting numbers from 1 to 450 aloud and individually.
- Reverse counting: counting backward from 450 to 1.
2. Ordering Numbers from 1 to 450:
- Demonstrate how to arrange numbers in ascending and descending order.
3. Addition and Subtraction of 2-Digit Numbers:
- Add two 2-digit numbers without regrouping.
Example: 34 + 45 = 79 - Subtract a 1-digit number from a 2-digit number.
Example: 56 – 7 = 49
4. Fractions and Shapes:
- Identifying fractions like ½, ⅓, and ¼ using shapes divided into equal parts.
- Colour shapes according to the fractions given.
5. Ordinal Numbers:
- Use ordinal numbers (1st, 2nd, 3rd, etc.) to arrange items in order.
- Example: The first, second, and third positions in a race.

Class Activity Discussion (15 FAQs with answers):
- What is counting?
Counting is the process of saying numbers in order, starting from one. - How do we order numbers?
We arrange numbers from smallest to largest or largest to smallest. - What is the sum of two numbers?
The sum is the total you get when you add two numbers together. - How do we subtract?
Subtraction is taking away one number from another. - What are fractions?
Fractions show parts of a whole. - Can fractions be used with shapes?
Yes, fractions can be shown with shapes divided into equal parts. - What is the ordinal number for the 3rd position?
The ordinal number is 3rd. - How do we count in reverse?
We start from a number and count backward to 1. - What is the difference between addition and subtraction?
Addition is putting numbers together, and subtraction is taking numbers apart. - What do we mean by a 2-digit number?
A 2-digit number is any number from 10 to 99. - How can we use counting in real life?
We use counting for things like knowing how many objects we have or how many people are in a group. - What do ordinal numbers help us do?
They help us show the order or position of things, like 1st, 2nd, and 3rd. - What is place value?
Place value shows the value of a digit depending on its position in a number. - Can we add numbers that have more than two digits?
Yes, we can add numbers with more than two digits, but we start with simpler ones first. - Why do we learn about shapes and fractions?
Fractions and shapes help us understand how parts make up a whole.
Teacher’s Activities:
