CONTENT OF THE LESSON

COUNTING IN THOUSANDS

We count in thousands when there are more than 3 digits in a number.

For example

Study the sequence below:

1. 1 001   1 002   1 003   _______   _______    _______    1 010
2. 1 000   2 000   3 000   _______   _______    _______    9 000
3. 1 111   2 222   3 333   _______   _______    _______    4 444
4. 2 220  2 230   2 240    _______   _______    _______    2 300
5. 5 600   5 650   5 700   _______   _______    _______    5 950

WRITE IN THOUSANDS

Write the sequence below:

1. 1 001   1 002   1 003   _______   _______    _______    1 010
2. 1 000   2 000   3 000   _______   _______    _______    9 000
3. 1 111   2 222   3 333   _______   _______    _______    4 444
4. 2 220   2 230   2 240   _______   _______    _______    2 300
5. 5 600   5 650   5 700   _______   _______    _______    5 950

VALUE AND PLACE VALUE OF WHOLE NUMBERS

• Whole Numbers

A whole number is a number without a fraction or decimal.

Every digit in a number, for example, 7 840 has the value and place value of each digit as follows:

This can also be represent the place-value of the number as:

1. The place value of 0 is unit,
2. The place value of 4 is tens,
3. The place value of 8 is hundreds,
4. The place value of 7 is thousands.

Further illustrations

Find the value value and place value for:

1. 316
2. 1 631
3. 1528

PRESENTATION

• To deliver the lesson, the teacher adopts the following steps:
1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;
2. Guides the pupils in revising the previous work on place value and value of a digit;
3. Guides pupils to find the place value and value of numbers;
4. Pupil’s Activities – Give the value and place value of each of the digits in the given number.
