Lesson Content/Board Summary

Whole Numbers 1 – 300

1. Collecting, Sorting, and Classifying Objects

Collecting means gathering items together. Sorting means putting objects into different groups based on a rule. Classifying means naming these groups.

Examples:

• Group all red objects together.
• Group all pencils together.
• Group all round objects together.

2. Identifying Numbers 1 – 300

Identifying a number means knowing what it looks like and what it represents. We can use number charts or flashcards to identify numbers.

Example: Showing a flashcard with ‘150’ and pupils saying “one hundred and fifty.”

3. Reading and Writing Numbers 1 – 300

Reading numbers means saying them correctly. Writing numbers means forming the digits correctly.

Examples of Reading:

• 101 – One hundred and one
• 245 – Two hundred and forty-five
• 300 – Three hundred

Examples of Writing:

• Write the number “two hundred and three”: 203
• Write the number “one hundred and sixty-seven”: 167

4. Ordering Numbers 1 – 300

Ordering numbers means arranging them from smallest to largest (ascending order) or largest to smallest (descending order).

• Ascending Order: Arranging numbers from the smallest to the largest.

  Example: Arrange 5, 2, 8 in ascending order: 2, 5, 8

• Descending Order: Arranging numbers from the largest to the smallest.

  Example: Arrange 5, 2, 8 in descending order: 8, 5, 2

5. Writing Numbers in Words

Writing numbers in words means spelling out the number names.

• 1 – One
• 70 – Seventy

Instructional Procedures

Whole Numbers 1 – 300

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: The teacher greets the pupils and asks them to count from 1 to 50 orally. The teacher then tells them that today they will learn about numbers up to 300.
Pupils’ Activity: Pupils greet the teacher and count from 1 to 50.
Learning Point: Pupils recall previous knowledge of counting and are prepared for the new topic.

Step 2: Collecting, Sorting, and Classifying Objects

Time: 10 minutes
Teaching Skill: Demonstration/Activity
Teacher’s Activity: The teacher provides various objects (e.g., pencils, erasers, stones) and demonstrates how to collect, sort them by colour or type, and classify them (e.g., “These are pencils,” “These are red objects”). The teacher then asks pupils to do the same in small groups.
Pupils’ Activity: Pupils observe the teacher’s demonstration, then collect, sort, and classify objects in their groups.
Learning Point: Pupils learn to categorize objects, which builds foundational number sense.

Step 3: Identifying Numbers 1 – 300

Time: 7 minutes
Teaching Skill: Visual Aid/Identification
Teacher’s Activity: The teacher uses flashcards or a number chart to show numbers from 1 to 300 randomly. The teacher calls out a number and asks pupils to identify it on the chart or identify the number on a flashcard shown.
Pupils’ Activity: Pupils identify the numbers shown on flashcards or pointed out on the number chart.
Learning Point: Pupils become familiar with the visual representation of numbers up to 300.

Step 4: Reading and Writing Numbers 1 – 300

Time: 8 minutes
Teaching Skill: Guided Practice
Teacher’s Activity: The teacher writes some numbers (e.g., 105, 212, 299) on the board and guides pupils to read them aloud. Then, the teacher dictates numbers for pupils to write in their notebooks (e.g., “one hundred and twenty”, “two hundred and fifty-six”).
Pupils’ Activity: Pupils read numbers written on the board and write dictated numbers in their notebooks.
Learning Point: Pupils practice reading and correctly forming numbers up to 300.

Step 5: Ordering Numbers 1 – 300

Time: 7 minutes
Teaching Skill: Explanation/Demonstration
Teacher’s Activity: The teacher explains ascending and descending order using simple examples (e.g., 10, 5, 15). The teacher then gives sets of numbers within the 1-300 range (e.g., 120, 100, 150) and guides pupils to arrange them on the board.
Pupils’ Activity: Pupils listen to the explanation and participate in arranging numbers in order on the board.
Learning Point: Pupils understand how to arrange numbers in ascending and descending order.

Step 6: Writing Numbers in Words (1 and 70)

Time: 5 minutes
Teaching Skill: Direct Instruction
Teacher’s Activity: The teacher writes the numbers 1 and 70 on the board and then writes their word forms: “One” and “Seventy”. The teacher guides pupils to spell and write these words in their notebooks.
Pupils’ Activity: Pupils copy the numbers and their word forms into their notebooks and practice spelling.
Learning Point: Pupils learn to write specific numbers in words.

Step 7: Evaluation/Review

Time: 5 minutes
Teaching Skill: Questioning/Assessment
Teacher’s Activity: The teacher evaluates the learning by asking the following questions:

1. Classify these objects into two groups: (Teacher presents a mix of pencils and erasers).
2. Identify the number on this flashcard (Teacher shows a flashcard with ‘234’).
3. Read the number: 187.
4. Write the number “two hundred and sixteen”.
5. Arrange these numbers in ascending order: 250, 100, 200.
6. Write the number 70 in words.

Pupils’ Activity: Pupils answer orally and in writing.

Learning Point: Pupils demonstrate understanding of the lesson.

Step 8: Conclusion

Time: 3 minutes
Teaching Skill: Summarization
Teacher’s Activity: The teacher summarizes the lesson by reminding pupils that they have learned to collect, sort, classify, identify, read, write, and order numbers up to 300, and also to write numbers 1 and 70 in words. The teacher assigns homework: write numbers 1-30 in their notebooks.
Pupils’ Activity: Pupils listen to the summary and copy the homework.
Learning Point: Pupils consolidate their learning and receive further practice.

Home Task: Solve two new exercises on Whole Numbers 1 – 300. Show each step and check each answer.

Lesson Keywords

• Whole Numbers – Numbers without fractions or decimals (0, 1, 2, 3…).
• Collect – To gather things together.
• Sort – To arrange things into groups based on a common feature.
• Classify – To name the groups after sorting.
• Ascending Order – Arranging numbers from smallest to largest.
• Descending Order – Arranging numbers from largest to smallest.
• Identify – To recognize or know something.

Differentiation

For struggling learners, the teacher will provide more one-on-one support during sorting activities and use only numbers up to 100 on flashcards initially. Advanced learners will be challenged to write more numbers in words (e.g., 100, 250) and arrange longer sequences of numbers.

Note for teachers using this lesson plan

Ensure a variety of physical objects are available for the sorting and classifying activity. Use clear and large flashcards for number identification. Encourage pupils to count aloud frequently to reinforce number recognition and sequence. Emphasize neatness when writing numbers.
