Algorithms and Programming

4.1

The student will construct sets of step-by-step instructions (algorithms) both independently and collaboratively

a) using sequencing;

b) using loops;

c) using variables to store and process data; and

d) performing number calculations on variables (e.g., addition, subtraction, multiplication and division). [Related SOL: Math 4.4, 4.5, 4.6]

algorithms-- sets of step-by-step directions to complete tasks
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.
