In computer science, input refers to the information or instructions given to a computer. Output is what the computer shows us after it processes the input. Think of it like this: you tell ScratchJr to move a character (input), and the character moves on the screen (output). ScratchJr worksheets help Grade 2 students understand these concepts through fun, interactive exercises.
ScratchJr uses blocks to represent different actions. When you connect these blocks, you're creating a sequence of instructions. The project 'reads' these instructions and performs them. The input is the blocks you use and how you arrange them, and the output is what you see happening on the screen!

When we give a command to ScratchJr, that's called __________. When ScratchJr shows us the result, that's called __________. ScratchJr uses colorful __________ to make programs. A __________ is a set of instructions. We use ScratchJr to learn about __________ and __________.
