Unlike is like when you have two toys: one is a shiny red car, and the other is a fluffy teddy bear. The car goes ‘vroom vroom’ and the teddy bear gives cuddles. They are different because they do not do the same things. The car is fast and the teddy bear is soft, so they are unlike each other.
Imagine you have two crayons: one is blue and the other is yellow. When you draw the sun, you use the yellow crayon, and when you draw the ocean, you use the blue one. They make different colors, so they are unlike each other.
Think about your favorite ice cream and your least favorite vegetable. Ice cream is sweet and makes you happy, while the vegetable might taste yucky to you. They don’t taste the same, so they are unlike.
In a group of animals, a cat and a fish are unlike. The cat has fur and says ‘meow’, while the fish swims and doesn’t make sounds like the cat. They live in different places, so they are unlike each other.
