## Worksheet for Class One

Addition and subtraction are two of the operations in math. Addition refers to the process of adding numbers. It tells us how much in all a number is. On the other hand, subtraction is the process of subtracting. It tells us how much is left.

In addition, we will make use of our fingers to add one digit. Below are the steps for adding one-digit:

Step 1:

Determine the numbers you must add.

Step 2:

Step 3:

Count them all.

Example:

5 + 2 = ?

Step 1:

Determine the numbers you must add.

5 and 2

Step 2: Step 3:

Count them all. Therefore 5 + 2 is 7

Moving on with subtraction, we will make use of our fingers to subtract one digit. Below are the steps for subtracting one-digit:

Step 1:

Determine the numbers you must subtract.

Step 2:

Use your finger in representing the numbers you’ll subtract. Count in your finger the larger number then take down each finger with the smaller number.

Step 3:

Count what’s left.

Example:

7 – 3 = ?

Step 1:

Determine the numbers you must subtract.

7 and 3

Step 2:

Use your finger in representing the numbers you’ll subtract.

• Count in your finger the larger number. • Next, take down each finger with the smaller number. Step 3:

Count them all. Therefore 7 – 3 is 7

## Applying:

Solve the following

1. 5 + 3= ?
1. 2 + 2= ?

1. 3 + 6= ?
1. 1 + 8= ?

1. 2 + 4= ?

1. 5 – 4= ?
1. 6 – 2= ?
1. 9 – 4 = ?

1. 8 – 3= ?
1. 9 – 7= ?
