Scratch : if-then

Moving a sprite with the arrow keys : This makes the program that you are making interactive

Learning Objective / Knowledge Intention

Code, so that a sprite can move using the left, right, up and down keys.

Understand that changing the Y-axis makes an object move up and down

Changing the x-axis makes an object move left and right
