. Addition

Addition is the process of adding things or numbers together.

Example:

• “If we have 2 apples and a friend gives us 3 more, how many apples do we have now?”

Answer: 2 + 3 = 5

How to teach children:

• Use real objects, such as ping pong balls, pencils, or toys, to help children understand the addition of numbers.

• Draw pictures or use tools, such as number blocks or number lines.

• Teach related vocabulary, such as “add”, “add”.

2. Subtraction

Subtraction is the process of removing one number from another.

Example:

• “We have 5 apples and we eat 2. How many apples do we have now?”

Answer: 5 - 2 = 3

How to teach children:

• Use real situations, such as dividing candy or fruit.

• Use illustrations or cards that show subtraction, such as crossing out the items that have been removed.

• Teach related vocabulary, such as “subtracted”, “left over”.

Fun and easy-to-understand teaching methods

1. Games and activities:

• Use games that have children match numbers or add numbers. For example, number bingo

• Creating a problem that connects to life, such as "If there are 10 pieces of candy in the bag and a friend asks for 3 pieces, how many pieces of candy are left?"

2. Learning media:

• Use cartoons, drawings or animations to help explain

• Use digital tools such as applications for practicing addition and subtraction

3. Connecting to daily life:

• Talk about things that children can easily understand, such as buying and selling candy at school

Tips:

• Get children involved, such as having them try to think of the answer themselves before explaining

• Encourage children when they do it right or give advice when they do it wrong

• Use repeated activities to help children remember better

Teachers can adjust it to suit children's understanding at each age as appropriate!
