Introduction

In Grade 2, we are learning about addition and subtraction within 100. This means we will be adding numbers together and taking some away to solve problems.

Addition

• What is addition? Addition is putting numbers together to find the total.

  Example: If we have 20 apples and add 30 more apples, how many apples do we have in total? $20 + 30 = 50$ apples.

• Practical Example: Imagine you have 40 marbles and your friend gives you 25 more marbles. How many marbles do you have now?

Subtraction

• What is subtraction? Subtraction is taking away some numbers from a group.

  Example: If we have 50 candies and eat 20 of them, how many candies are left? $50 - 20 = 30$ candies left.

• Practical Example: You have 60 balloons, and 25 balloons popped. How many balloons are still okay?

Fun Activity

Let's play a game called "Add or Subtract":

• Grab some toys or objects around you.
• Ask a friend to give you a number to add or subtract.
• Use the toys to solve the problem and have fun!

Remember

• Always line up the numbers neatly when adding or subtracting.
• Double-check your work to avoid mistakes.
• Practice regularly to become a math pro!
