Various experiments have proven that students look forward to classes where the teacher involves them in different exercises.

The Fish TALE
Let’s Revise
The biggest fish is the whale shark. It is actually not a whale but a big fish.
Whales are different from fish. Whales breath like we do, through their noses.
Fish have no noses and they take in water, not air.
Whales give birth to babies, but fish lay eggs.
One whale shark is as long as 18 m.
