Developing Algorithms

Learning Objective: Compare multiple algorithms to determine if they yield the same side effect or result

AAP-2.L.1

Algorithms can be written in different ways and

still accomplish the same tasks.

AAP-2.L.2

Algorithms that appear similar can yield

different side effects or results.

AAP-2.L.3

Some conditional statements can be written as

equivalent Boolean expressions.

AAP-2.L.4

Some Boolean expressions can be written as

equivalent conditional statements.

AAP-2.L.5

Different algorithms can be developed or used

to solve the same problem.

Learning Objective

For algorithms:

a. Create algorithms.

b. Combine and modify existing algorithms

Algorithms can be created from an idea, by

combining existing algorithms, or by modifying

existing algorithms.

AAP-2.M.2

Knowledge of existing algorithms can help

in constructing new ones. Some existing

algorithms include:

• determining the maximum or minimum value

of two or more numbers

• computing the sum or average of two or

more numbers

• identifying if an integer is or is not evenly

divisible by another integer

• determining a robot’s path through a maze

AAP-2.M.3

Using existing correct algorithms as building

blocks for constructing another algorithm

has benefits such as reducing development

time, reducing testing, and simplifying the

identification of errors.
