Learning Objectives

Indicator: B9.4.2.1.2 - Translate a Flowchart algorithm to Pseudocode format and vice versa

By the end of the lesson, learners can:

Identify the key components of a flowchart (start/end, process, decision, input/output, arrows) and match them to their equivalent Pseudocode statements.
Translate a given flowchart algorithm into correct Pseudocode format, using keywords like START, INPUT, PROCESS, IF…THEN…ELSE, and STOP.
Convert a given Pseudocode algorithm into a flowchart format, arranging the correct shapes and arrows in the proper order.
Check that a translated algorithm (flowchart to Pseudocode or vice versa) preserves the same logic and produces the same outcome as the original.
Justify their choice of Pseudocode keywords or flowchart symbols when translating between the two formats.

Exemplars (from the NaCCA curriculum)

1. Write an algorithm using flowchart format. Convert or translate the same flowchart algorithm into a Pseudocode format. (do a vice versa translation example to reinforce critical thinking)
