WHAT ARE BLOCKS?
Blocks are just like pieces of the jigsaw puzzle available in different shapes. They connect to
each other vertically to create code in Scratch. Each block type has its own shape and its own
slot shape for it to be inserted into. You simply drag these blocks into the coding area to create
a script. Series of connected blocks are called scripts. There are nine main block categories
in Scratch 3.0. Let us discuss each of these categories one by one.
