1st Term Week 1 Lesson not for JSS 1: Whole Numbers (Place Value, Ordering & Properties)

Week 1: Whole Numbers (Place Value, Ordering & Properties)

💡 Teacher's Overview & Guide

• Subject: Mathematics
• Class: JSS 1 | Term: 1st Term (Week 1)
• Duration: 4 Days (4 Period Allocations)
• Instructional Materials: Standard JSS 1 Mathematics textbook, place value charts, abacus, inequality symbol flashcards (<, >, =).
• Textbook Integration Strategy: Use the school textbook's introductory chapter on Whole Numbers for guided class reading, worked examples, and assigning differentiated classwork/homework.

Behavioral Objectives

By the end of the week, students should be able to:

1. Identify and state the place value and value of digits in large whole numbers (up to millions and billions).
2. Read, write, and expand large whole numbers in figures and words as illustrated in the textbook.
3. Compare and order whole numbers using inequality symbols (<, >) and sort them into ascending/descending order.
4. Apply fundamental properties of whole numbers (Commutative, Associative, Distributive, and Identity) to solve exercises in the textbook.

Day-by-Day Instructional & Textbook Integration Plan

Day 1: Place Value and Value of Digits

Teacher's Action: Direct students to open the textbook chapter on Whole Numbers — Place Value. Explain the place value chart (Units, Tens, Hundreds, Thousands, Millions, Billions). Work through Example 1 from the textbook on the board, emphasizing the difference between place value (position) and digit value.

Textbook Activity: Assign selected questions from the textbook's introductory exercise for classwork to test place value recognition.

Day 2: Writing and Expanding Whole Numbers

Teacher's Action: Refer students to the section on Writing Numbers in Words and Expanded Form in their textbook. Demonstrate proper comma placement for grouping digits in thousands and millions. Solve sample expansion problems from the text step-by-step.

Textbook Activity: Have students complete the textbook exercise on converting numbers from words to figures and writing numbers in expanded form.

Day 3: Ordering and Comparing Whole Numbers

Teacher's Action: Guide students to the textbook section covering Ordering of Whole Numbers. Demonstrate left-to-right digit comparison. Explain how to use comparison symbols (<, >, =) and arrange set numbers into ascending (smallest to largest) and descending (largest to smallest) order.

Textbook Activity: Assign practice problems from the textbook where students compare pairs of large numbers and order multi-digit number sets.

Day 4: Properties of Whole Numbers

Teacher's Action: Refer to the textbook rules on Number Properties. Present and illustrate: Commutative Property ($a + b = b + a$), Associative Property ($a + (b + c) = (a + b) + c$), Distributive Property ($a \times (b + c) = ab + ac$), and Identity elements ($0$ for addition, $1$ for multiplication).

Textbook Activity: Direct students to complete the chapter review exercise in their textbook as an evaluation measure.

📝 Board Note for Students

1ST TERM - WEEK 1: WHOLE NUMBERS

1. Place Value Structure:

Billions (B) | Millions (M) | Thousands (Th) | Hundreds (H) | Tens (T) | Units (U)

Example: In the number 7,456,209:

• Place value of 4 = Hundred Thousands (Value = 400,000)
• Place value of 5 = Ten Thousands (Value = 50,000)

2. Expanded Form:

64,305 = (6 × 10,000) + (4 × 1,000) + (3 × 100) + (0 × 10) + (5 × 1)

3. Key Properties of Whole Numbers:

• Commutative: $a + b = b + a$ and $a \times b = b \times a$
• Associative: $(a + b) + c = a + (b + c)$
• Distributive: $a \times (b + c) = (a \times b) + (a \times c)$
• Identity Elements: $a + 0 = a$ (Additive) | $a \times 1 = a$ (Multiplicative)

Evaluation & Textbook Assignment

Note: Teacher should fill in specific page/exercise numbers according to the active school textbook.

1. Classwork: Complete Exercise 1A (Questions 1–5) in your Mathematics textbook.
2. Homework: Complete Exercise 1B (Questions 1–10) in your Mathematics textbook.
3. Self-Check Challenge: State the property shown: 8 \times (10 + 2) = (8 x10) + (8 x 2)
