Equal - We say that two or more things are equal if they have the same quantity or value.

Inequality - Inequality occurs when things are not equal. We use different symbols to show this.
Common misconception
The part changes size when the whole changes.
Use the bottles example in the slides to overcome this. Have a range of different sized containers for water and demonstrate the concept practically.
