ELI5: Explain Like I'm 5

Pentomino

Imagine you have some blocks that all have a different shape, but they're all made up of 5 smaller squares put together. That's a pentomino!

There are 12 different shapes of pentomino blocks. Some look like a capital letter L, some look like a plus sign, and some look like a weird squiggly shape.

People like to play games and do puzzles with pentomino blocks. You might try to fit all 12 shapes into a bigger square, without any spaces left over. Or you might try to make a special pattern or design with the blocks.

Pentominoes can be fun to play with and they can help you learn about shapes and patterns. So give it a try and see what you can create!
