Counting, Reading and Writing Numbers 6–9 for Primary 1

Whole numbers 6-9

Performance Objectives

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

1. sort and classify numbers of objects in a group or collection;
2. identify number of objects in a group or collection;
3. count and read correctly from 1-9;
4. write correctly number 6- 9;
5. arrange the numbers 6-9 in order of their magnitudes (quantities).

Understanding Numbers 6 to 9

Numbers help people count things around them. They are used to know “how many” of something there is. This unit focuses on understanding, counting, reading, and writing the numbers 6, 7, 8, and 9.

Sorting and Classifying Objects

Sorting means putting things that are alike together. Classifying means arranging objects into different groups based on a rule, such as their type, colour, or size. For numbers, objects can be classified by how many there are in a group.

To understand numbers 6 to 9, objects can be sorted and grouped into collections of six, seven, eight, and nine items. This helps to see the quantity each number represents.

Imagine a collection of different items like balls, pebbles, buttons, and leaves. These items can be sorted into separate piles. Then, each pile can be classified by counting how many items are in it.

Identifying Numbers 6 to 9

After sorting and classifying objects, the next step is to identify the number that represents the quantity in each group. Each number has a special symbol, called a numeral, that stands for its quantity.

Number 6

When there are six objects in a group, the number is 6. For example, six oranges or six bottle tops.

Number 7

When there are seven objects in a group, the number is 7. For example, seven pebbles or seven buttons.

Number 8

When there are eight objects in a group, the number is 8. For example, eight leaves or eight balls.

Number 9

When there are nine objects in a group, the number is 9. For example, nine bottle tops or nine buttons.

Counting and Reading Numbers 1 to 9

Counting is saying numbers in order while pointing to each object. Reading numbers means saying the name of the numeral when it is seen.

To count from 1 to 9, start from one and continue in order, touching each object as its number is said. For example, when counting bottle tops, touch the first one and say “one”, touch the second and say “two”, and so on, until all nine bottle tops are counted.

The numbers from 1 to 9 are:

1. 1 (one)
2. 2 (two)
3. 3 (three)
4. 4 (four)
5. 5 (five)
6. 6 (six)
7. 7 (seven)
8. 8 (eight)
9. 9 (nine)

Practise counting different groups of objects up to nine. Also, practise reading the numerals 1 to 9 from flash cards or written on a board.

Writing Numbers 6 to 9

Writing numbers correctly helps others understand the quantity being represented. Each number has a specific way it is formed.

How to Write Number 6

Start from the top, curve down and to the left, then bring the line around to meet itself, forming a loop at the bottom.

$$
\text{Start at the top, curve down and around to close the loop.}
$$

How to Write Number 7

Start with a straight line across the top from left to right. Then, draw a slanted line downwards from the right end of the top line to the bottom left.

$$
\text{Draw a line across, then a slanted line down.}
$$

How to Write Number 8

Start from the top, make an ‘S’ shape, then curve back up to meet the starting point, forming two loops, one on top of the other.

$$
\text{Make an ‘S’ shape and close it at the top.}
$$

How to Write Number 9

Start by drawing a circle or a loop at the top. Then, draw a straight line downwards from the right side of the loop.

$$
\text{Draw a circle at the top, then a straight line down.}
$$

Ordering Numbers 6 to 9

Ordering numbers means arranging them from the smallest quantity to the largest quantity, or from the largest quantity to the smallest quantity. This is also called arranging them by their magnitude.

To arrange numbers 6, 7, 8, and 9 in order of their magnitudes, think about the quantity of objects each number represents. A group of 6 objects is smaller than a group of 7 objects, and so on.

Arranging numbers from smallest to largest:

1. 6
2. 7
3. 8
4. 9

Arranging numbers from largest to smallest:

1. 9
2. 8
3. 7
4. 6

A number line can help to see the order of numbers clearly. Numbers on the left are smaller, and numbers on the right are larger.
