Word of the Day: Thesis statement - A thesis statement is a strong statement that you can prove with evidence. It is not a simple statement of fact.

It can also be thought of as the angle or point of view from which you present your material.

Word of the Day: Variables - Sometimes, you want execute some statement multiple times, each time varying your behavior ever so slightly. We thus turn our attention to variables.
In programming, a variable is a placeholder for some value, much like x and y are popular variables in algebra. In Scratch, variables are represented with blocks shaped like elongated circles, uniquely labeled by you. Variables, generally speaking, can be local or global. In Scratch, a local variable can be used by just one sprite; a global variable can be used by all of your sprites.
Variables allow us, for instance, to instruct a sprite to count up from 1:
A variable that only takes on a value of true (i.e., 1) or false (i.e., 0), incidentally, is called a Boolean variable.
