Area and perimeter of a triangle
Another way to possibly introduce, or reinforce, the area of a triangle and perimeter could be to show this gif:
Ask, "What do you notice? What do you wonder?". After some discussion pose, if not already asked, the following questions:
When is the area the least/greatest?
When is the perimeter the least/greatest?
After some discussion show this gif.
