PERIOD 1 & 2

PRESENTATION

Step

Teacher’s Activity

Pupil’s Activity

Step 1 - Introduction

Explains what whole numbers are and gives examples from thousands to billions.

Pupils listen and respond to questions.

Step 2 - Explanation

Writes large numbers on the board and reads them aloud. Introduces counting in thousands, millions, billions.

Pupils repeat and practice reading large numbers.

Step 3 - Demonstration

Demonstrates how to use the abacus or place value chart to build large numbers.

Pupils use their abacus or charts to form and read numbers.

Step 4 - Note Taking

Pupils copy examples and notes from the board.

Pupils take notes.

NOTE (On the Board):

  • 1,000 = One thousand
  • 1,000,000 = One million
  • 1,000,000,000 = One billion
  • 345,678,910 → Three hundred and forty-five million, six hundred and seventy-eight thousand, nine hundred and ten

EVALUATION:

  • Pupils write and read out large numbers from flashcards.
  • Oral drills on counting in thousands, millions, and billions.

CLASSWORK:

  • Write these numbers in figures and words:
  1. 245,000,000
  2. 999,000,000
  3. 1,000,000

ASSIGNMENT:

  • Write 5 large numbers in both figures and words.

 

PERIOD 3 & 4

PRESENTATION

Step

Teacher’s Activity

Pupil’s Activity

Step 1 – Introduction

Reviews previous work, introduces place value and values of digits.

Pupils respond to review questions.

Step 2 – Explanation

Shows how to identify place value and value of digits in large numbers.

Pupils follow along and identify place value.

Step 3 – Demonstration

Uses place value chart to break down numbers.

Pupils do the same with guided examples.

Step 4 - Note Taking

Teacher summarizes. Pupils copy into their books.

Pupils take notes.

NOTE (On the Board):

  • Number: 932,456,718
  • Place value of 3: Hundred millions
  • Value of 3: 300,000,000

EVALUATION:

  • Pupils identify the value and place value of given digits in large numbers.

CLASSWORK:

  • Write the place value and value of underlined digits in:
  1. 534,000,000
  2. 21,764,000
  3. 9,103,456

ASSIGNMENT:

  • Write 5 large numbers and identify the place value of any two digits in each.
