Thinking Like a Computer: Algorithms Before Syntax: Computer Science Unit 1, Grade 10 (Letters & Devotion)

Description

Thinking Like a Computer: Algorithms Before Syntax is Unit 1 of Computer Science Principles: Computation, Data, and Society (Part 1) (Grade 10), the Letters & Devotion Computer Science course, complete in one printable PDF: 9 lessons, the unit check-up and the answer key, 75 pages.

• The definitions of algorithm, sequence, selection, iteration, decomposition, and abstraction
• Sequential execution of a pseudocode algorithm and its effect on variable values
• Selection and iteration control structures and their effect on variable state across multiple steps
• Sequence, selection, and iteration as structural categories of algorithmic control flow
• Off-by-one logic errors in loop boundary conditions
• Decomposition of a problem into independently justifiable sub-steps
• Abstraction as deliberate concealment of implementation detail, and its tradeoffs for the user
• Robustness of a decomposition’s boundaries under changed problem constraints
• Correspondence between flowchart and pseudocode representations of the same algorithm

Every lesson is written for a parent with no teaching background: it opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet you may copy for your household. Scripture references are King James Version throughout. Black-and-white, 8.5 x 11 in. The whole year of this course is also in this store as a single book.
