The Four Operations

I am learning to identify the four operations, addition, subtraction, multiplication and division to solve problems.

I know I can do it when I can identify what operation to use to solve a problem.

Watch

Today we are looking at the four operations in mathematics:

• Addition
• Subtraction
• Multiplication
• Division

It is really important to look carefully at the question, when solving mathematical problems.

What is the question asking and what operation do I need to use.

Addition and Subtraction

Learning Intention: I am learning to use my understanding of addition and subtraction to solve problems and represent my thinking in different ways.

I am successful when i can solve an open ended equation in multiple ways.

2 Number Problem Solving Activity

I am thinking of two numbers.

When I subtract one from the other, the total is 16.

How many ways can you do this?

Here is an example below:

Now try another number.

Addition

Addition can be solved and represented in many ways. Choose a sum (below) and represent it by completing the tasks.

4 + 8 =12

17 +26 = 43

88 + 53 = 141

• Worded problem: Write a number story

• Visual: Draw a picture

• Number line: Show the problem on a number line

• Concrete: Use concrete materials (or draw them)

Here is an example below:
