A pyramid is like a giant triangle made from blocks. Imagine a big cake with layers, but instead of being round, it’s shaped like a triangle that points up to the sky. The bottom is wide and flat, and as you go up, it gets smaller and smaller until it reaches the top, which is a point.
Think of a pyramid like a mountain made by people. Long ago, people built these to be strong and last a long time. They used big stones and stacked them carefully. It’s like when you build with blocks, and you make sure each block fits just right so your tower doesn’t fall over.
A pyramid can also be like a sandcastle. When you build a sandcastle at the beach, you start with a big base and make it smaller as you go up. This way, it doesn’t fall down easily. Pyramids are special because they were used as places to keep important things safe, like treasures or even to honor special people a long time ago. They are very strong and have been around for a really, really long time.
