What are three major periods?

There are three major periods that help us understand how time works in big chunks, like chapters in a story or sections in a game.

Imagine you have a really long storybook, and it's divided into three parts: the beginning, the middle, and the end. These are kind of like the three major periods we're talking about.

• The first part is when everything starts, like when you sit down to play with your toys.
• The second part is in the middle, like when you’re having fun and things get a little more exciting.
• The third part is at the end, like when it's time to clean up and go to bed.

Think about your day. It has different parts too:

• Morning is like starting something new, like getting ready for school.
• Afternoon is in the middle, like playing with friends during recess.
• Evening is near the end, like when you're getting ready to go to bed.

These three big chunks of time help us organize what happens around us, just like how your day has different parts.
