Objective (5 – 7 minutes)

• To familiarize students with natural numbers up to 100, enabling them to understand the concept of counting and the number sequence. The educator ensures that they are comfortable identifying the numbers.
• Teach the learners how to count numbers between 1-100 while observing the sanctity of the sequence. The instructor demonstrates ways to count the numbers such as counting in ones (1,2,3,…), twos (2,4,6,8,…), fives (5, 10,15…), among others. This fosters their understanding on number patterns.
• Introduce learners to the concept of odd and even number. The teacher should teach the learners how they can differentiate between the two and their position on the number series. This may be presented in form of fun games or activities that are engaging to them.

Sub-Objectives

• Develop team-working skills by encouraging group work while finding solutions for the numerical problems.
• Arouse the students interest in Mathematics by introducing the subject fun and interactive

Introduction (10 - 15 minutes)

1- To introduce the lesson the teacher can begin by reminding the learners what natural numbers( numbers that are applied in counting things like 1 2 3 4 etc )are all about and their usage in our day-to day lives for instance when counting the number of students present in class to determine their attendance, counting the number of apples in a basket, counting the birds in the sky e.t. c. This aids in establishing a link between mathematics to real world application making it relatable thus interesting.

2 - The teacher can pose a question such as; "How many fingers are in your hands? What of the legs? Let's count them together." This encourages active engagement in class from learners and readies them for a counting exercise that follows.

3- The educator then proceeds to introducing the concept of number sequence and why it is important . He/ She can explain by stating " Imagine if there was no sequence in numbers? It would become so tasking to count and even locate a certain number right? This makes it very necessary. It helps organize the numbers for proper understanding.

4. To heighten their curiosity, the teacher can introduce some mathematics trivia related to the topic. For example; they could be informed that the number 100 is a square number (10 x 10 =100) and that all even numbers have one thing in common; they end with either 0,2, 4,6, or 8.

5 -Finally the teacher should create awareness on why this topic is important . "Counting to 100 is such a big milestone in Mathematics. This helps in solving advanced problems like addition and subtractions of big numbers. Let us begin this journey and see how far we go!"

Elaboration (20 – 25 minutes)

Suggested activity 1: "Counting together"

• Divide learners into small groups of four to five and provide each set up with a big piece of paper and colour pens

• The educator then challenges each group to count from 1- 100 on their sheets with a twist; any number that falls on even numbers, they ought to draw a small circle while odd numbers are represented by a square

• The teacher should move around the classroom during the process giving guidance and support where necessary.

• At the end of the exercise , each group shares their findings with their counter parts The teacher can use this opportunity to drive home the concept of odd and even numbers as well as their positions in the sequence.

** Suggested activity 2; "Number Hunt" **

• The teacher hides pieces of cards in various areas of the room. These cards have numbers inscribed on them which are less than 100

• Learners in teams move around searching for these cards and when they get one, they place it on a number line in the correct order

• To increase the challenge, students can be instructed to specifically look out for either even or odd numbers and mark them with a certain color

• After the activity ,each group presents their number line arrangement and teacher uses this as reinforcement for number sequence , odd and even number.

After any of the above activities the educator reserves some time for reviewing the learnt concept reinforcement of key points as well as answering arising questions. This should be done to enlighten learners and boost their confidence before moving to the next stage

Recapitulation ( 10- 12minutes )

• Having covered the topic, the teacher brings the class to a round table discussion. Each group shares its findings and the thought process they applied. This encourages communication and cooperation among learners. During this discourse the teacher poses question intended to test their understanding. For instance; " How did you determine whether a particular number was odd or even ?" or " How did you arrive at the correct arrangement on the number line? " This helps gauge their understanding and note any challenges they might have encountered.

-Secondly, the educator leads the students into reflecting on the lesson. He/She initiates this by questioning ; " What was your biggest challenge during the counting activity? On the other hand , what was easiest for you ?" and " What have you learnt that you think can be applicable in other circumstances?" This allows learners to introspect on the knowledge gained and discover areas that need improvement.

• The teacher should connect the undergone activities to the theory learnt and its real world application by stating ; " You see the role of a number sequence makes it easy to organize and even identify patterns in numbers? This proves very helpful in the field of Mathematics in fact in other areas of study. To illustrate; If you were to play hide and seek , the number sequence will enable you in counting up to 100. Furthermore if you are sharing sweets with friends the same number sequence comes in handy to ensure fair distribution."

• To finalize the session the facilitator requests the students take a moment and reflect on what was covered. Two simple question are paused to direct their contemplation; “What was most interesting about counting numbers up to 100 that you have learnt today ?" and “In what circumstances do you suppose what you learnt today can be applied?" The responses are shared with the whole group if they wish

• The teacher should remind the learners that they are open to ask questions and seek further clarification in case of need . He /She should instill in them that knowledge acquisition is a continuous journey where each individual progresses at their pace

• Lastly the educator commends the students efforts for the commendable work they did and enthusiasm they exhibited throughout. He/she further encourages them in continuing their quest for knowledge and exploration in the vast field known as Mathematics

Conclusion(5 – 7 minutes)

• To conclude, the instructor summarizes key points learnt. He reminds the class on counting of natural numbers up to 100 , the significance of number sequence , and distinguishing odd numbers from even ones. He/ She can put it as ; " Today we have explored counting up to 100 not forgetting the importance of a number sequence . We have also learnt the difference that exists in odd and even number.

• Secondly the teacher reiterates how practical the learnt concept is. “ You can apply this knowledge any time you need to count up to 100 and beyond . The knowledge of odd and even numbers can also come in handy in solving puzzles or in a game situation. For example , if you are playing a game known as rock ,paper, scissors, you know that if both of you choose odd number of fingers the result is inevitably a tie"

• The teacher should explain how theory, practice and application interconnected in the topic handled . He / she can present it in manner such as; " We begun with a theoretical approach by learning about natural numbers and the number sequence . This theory was put into practice during the activities where we counted up to 100 and arranged numbers. Finally we joined theory and practice to real world application whereby we discovered the relevance of these concepts."

• The educator can suggest extra resources that learners can use to enhance their knowledge . This may range from numerical books geared towards children, online counting games or even activities that can be carried out at home such as counting stairs as they use them or counting the number of vehicles passing by as they play outside.

• To conclude the lesson, he / she emphasizes on the significance of the knowledge gained by saying; "You ought to always bear in mind that Mathematics is a subject that cuts across all facets of our daily lives. Right from when we wake up till we go to bed, we interact with numbers when counting , organizing, measuring and even problem solving . Therefore , every Mathematics lesson is a step closer in becoming confident and competent mathematicians.

• Finally he/ she appreciates the students for their active participation during the class session and urges them to keep up the zeal in seeking knowledge in the subject area of mathematics and even beyond.
