During this operation, they form new
relationships and discover

- A way of putting things together

6. Subtraction concept
There are 3 types of subtraction
• Take away… “ I had 6 bananas and I ate 2. How

Each concepts can have different skills
associated with them. Some skills are:
• Maths language
• Rainbow numbers
• Place value charts
• Materials language

9. What are different strategies that
can be used?
These are different and efficient ways to
approach teaching operations in mathematcis.
• It is a way of processing information e.g
mental
• Algorithms
• Understanding relationships of numbers
• Practicing methods
These are without pencils, paper or calculators.
