Lesson Content/Board Summary

OǸKÀ (Numbers)

Ka Oǹkà Láti Òkànlélógórùn-ún Dé Àádójọ (Counting Numbers from 101 to 150)

Yoruba numbers are often formed by adding or subtracting from base numbers. Counting from 101 to 150 follows specific patterns.

Examples of counting:

101 – Òkànlélógórùn-ún (one added to 100)
105 – Àrúnlélógórùn-ún (five added to 100)
110 – Èwàálélógórùn-ún (ten added to 100)
120 – Òjílélógórùn-ún (twenty added to 100)
130 – Ògójìlélógórùn-ún (thirty added to 100)
140 – Ògótàlélógórùn-ún (forty added to 100)
150 – Àádójọ (one hundred and fifty)

Àlàyé Nípa Oǹkà 110 (Explanation about Number 110)

The number 110 in Yoruba is Èwàálélógórùn-ún. This literally means “ten added to one hundred”. It is formed by combining ‘èwàá’ (ten) and ‘lélógórùn-ún’ (added to one hundred).

Other examples of this pattern:

102 – Èjílélógórùn-ún (two added to 100)
107 – Èjélélógórùn-ún (seven added to 100)

Àròpò Àti Àyọkúrò Oǹkà (Addition and Subtraction of Numbers)

Àròpò (Addition): This is the process of combining two or more numbers to find their total sum. The sign for addition is ‘+’.

Example:

Méjì + Méta = Àrún (2 + 3 = 5)
Èwàá + Ògójì = Aádóta (10 + 40 = 50)

Àyọkúrò (Subtraction): This is the process of taking one number away from another to find the difference. The sign for subtraction is ‘-‘.

Example:

Àrún – Méjì = Méta (5 – 2 = 3)
Aádóta – Èwàá = Ògójì (50 – 10 = 40)

Teaching Methods/Instructional Techniques

Discussion, Lecture, Demonstration, Question and Answer, Visual Aids

Instructional Procedures

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: The teacher greets the pupils and reviews the previous lesson on counting numbers up to 100. The teacher then introduces the new topic, “OǸKÀ”, and states that the lesson will focus on counting beyond 100, and performing simple addition and subtraction in Yoruba.
Pupils’ Activity: Pupils respond to greetings, recall the previous lesson, and listen attentively to the introduction of the new topic.
Learning Point: Pupils connect new learning with previous knowledge and understand the focus of the lesson.

Step 2: Presentation of Numbers 95-117

Time: 10 minutes
Teaching Skill: Explanation/Demonstration
Teacher’s Activity: The teacher uses the Yoruba number chart and number cards to demonstrate counting from 95 to 117. The teacher pronounces each number clearly and explains the formation of some key numbers like 101 (Òkànlélógórùn-ún) and 110 (Èwàálélógórùn-ún).
Pupils’ Activity: Pupils listen, observe the chart, and repeat the numbers after the teacher. They also ask questions for clarification.
Learning Point: Pupils learn to pronounce and identify Yoruba numbers from 95 to 117.

Step 3: Explanation of Number 110

Time: 5 minutes
Teaching Skill: Explanation
Teacher’s Activity: The teacher provides a detailed explanation of the formation and meaning of the number 110 (Èwàálélógórùn-ún), breaking down its components (èwàá + lé + ogórùn-ún). The teacher also provides other examples following this pattern.
Pupils’ Activity: Pupils listen and try to understand how the number is formed. They may offer other examples.
Learning Point: Pupils understand the structure and meaning of compound Yoruba numbers.

Step 4: Introduction to Addition (Àròpò)

Time: 5 minutes
Teaching Skill: Explanation/Illustration
Teacher’s Activity: The teacher explains the concept of addition (Àròpò) using simple real-life scenarios and numerical examples. The teacher writes simple addition problems on the board and guides pupils to solve them in Yoruba.
Pupils’ Activity: Pupils listen to the explanation, observe the examples, and attempt to solve the problems.
Learning Point: Pupils understand the concept of addition in Yoruba and can solve simple problems.

Step 5: Introduction to Subtraction (Àyọkúrò)

Time: 5 minutes
Teaching Skill: Explanation/Illustration
Teacher’s Activity: The teacher explains the concept of subtraction (Àyọkúrò) using simple real-life scenarios and numerical examples. The teacher writes simple subtraction problems on the board and guides pupils to solve them in Yoruba.
Pupils’ Activity: Pupils listen to the explanation, observe the examples, and attempt to solve the problems.
Learning Point: Pupils understand the concept of subtraction in Yoruba and can solve simple problems.

Step 6: Practice Addition and Subtraction

Time: 5 minutes

Pupils’ Activity: Pupils solve the given problems individually or in pairs, writing their answers in their exercise books.
Learning Point: Pupils practice and improve their skills in performing addition and subtraction using Yoruba numbers.

Step 7: Evaluation/Review

Time: 5 minutes

Teaching Skill: Questioning/Assessment

Teacher’s Activity: The teacher evaluates the learning by asking the following questions:

Ka oǹkà láti 100 dé 105 ní èdè Yoruba. (Count numbers from 100 to 105 in Yoruba.)
Kí ni itumo Èwàálélógórùn-ún? (What is the meaning of 110?)
Ṣe àròpò yìí: Méta + Méfa = ? (Perform this addition: 3 + 6 = ?)
Ṣe àyọkúrò yìí: Méjèèjè – Méjì = ? (Perform this subtraction: 7 – 2 = ?)

Pupils’ Activity: Pupils answer orally and in writing.

Learning Point: Pupils demonstrate understanding of the lesson.

Step 8: Conclusion

Time: 5 minutes
Teaching Skill: Summarization
Teacher’s Activity: The teacher summarizes the key points of the lesson, emphasizing the importance of counting, addition, and subtraction in Yoruba. The teacher assigns homework for pupils to practice counting from 101 to 150 and to solve two simple addition and two simple subtraction problems.
Pupils’ Activity: Pupils listen to the summary and copy down the homework assignment.
Learning Point: Pupils consolidate their learning and prepare for further practice.

Lesson Keywords

Oǹkà – Numbers
Àròpò – Addition
Àyọkúrò – Subtraction
Òkànlélógórùn-ún – 101
Èwàálélógórùn-ún – 110
Àádójọ – 150

Differentiation

For pupils who grasp concepts quickly, the teacher can provide more complex addition and subtraction problems or ask them to count higher numbers. For pupils needing more support, the teacher will provide one-on-one guidance, use more visual aids, and give simpler counting and calculation tasks.

Note for teachers using this lesson plan

Teachers should ensure active participation from all pupils, especially in counting and repeating numbers. Encourage pupils to use Yoruba terms throughout the lesson. Provide ample opportunities for practical application of addition and subtraction concepts.
