a) using sequencing;

b) using loops;

c) using variables;

d) using mathematical operations (addition, subtraction, multiplication and division) variable to manipulate a variable; and [Related SOL: Math 5.19]

e) using conditionals (if-statements).

Terminology

• block based programming -- coding within a programming language where instructions are mainly represented as blocks. Scratch is a block-based programming language.
• unplugged activities --an activity that can be conducted without the use of computers or electronic equipment.
• sequencing--arranging in a particular order
• loop -- A programming structure that repeats a sequence of instructions as long as a specific condition is true.
• event -- Any identifiable occurrence that has significance for system hardware or software. User-generated events include keystrokes and mouse clicks; system-generated events include program loading and errors.
• variable -- A symbolic name that is used to keep track of a value that can change while a program is running. Variables are not just used for numbers; they can also hold text, including whole sentences (strings) or logical values (true or false). A variable has a data type and is associated with a data storage location; its value is normally changed during the course of program execution. Note: This definition differs from that used in math.
• conditional -- A feature of a programming language that performs different computations or actions depending on whether a condition evaluates to true or false. (eg if x =1, add 1)
