What contents should be contained in a five paragraph essay?

Yesterday our instructor/teacher introduced us to the five paragraph essay. It contains the following types of paragraphs:

Introduction & thesis:

In the introduction paragraph, you should have** a hook to catch the reader’s attention. And express the thesis statement combined with examples, in most conditions we restricted in 3 thesis [?? "we restrict this to 3 sentences."?]. Also through your thesis statement, the reader should find out your stance about this topic.

Body paragraph:

The body paragraph is where you explain your opinion in detail to help the reader to understand your statement. It should contain a topic sentence which is a statement for your thesis, and this sentence should be the first sentence of the paragraph. And at the end of the paragraph, you could restate your opinion again, but a better way to do this is to build a transition to the next paragraph.

Conclusion:

Basically you restate all your thesis ideas again in the conclusion which gives a summary to the readers to help them remember your thesis better. But you better arrange it different from the way you say it in the introduction paragraph to diversify your essay.

Note that commas and colons should not have spaces before them.]
