Standards - Digital Literacy & Computer Science

Examples: Tying shoes, making a sandwich, brushing teeth.

Examples: Unplugged coding activities, sequence of instruction.

Examples: Unplugged coding activities, illustrate sequence of a process such as baking a cake.

Example: Multiple paths exist to get home from school; one may be a shorter distance while one may encounter less traffic.

Example: Trace the path of a set of directions to determine success or failure.

Examples: Program the movement of a character, robot, or person through a maze. Define a variable that can be changed or updated.

Examples: Using if/then/else (If it is raining then bring an umbrella else get wet).

Example: Flowcharts use shapes to indicate what to do at each step while pseudocode uses text.

Examples: Sequencing is doing steps in order (put on socks, put on shoes, tie laces); selection uses a Boolean condition to determine which of two parts of an algorithm are used (hair is dirty? True, wash hair; false, do not); iteration is the repetition of part of an algorithm until a condition is met (if you’re happy and you know it clap your hands, when you’re no longer happy you stop clapping).

Example: Automated vacuum pseudocode - drive forward until the unit encounters an obstacle; reverse 2 in.; rotate 30 degrees to the left, repeat.

Examples: Debit card transactions are approved until the account balance is insufficient to fund the transaction = iteration, do until.

Examples: Lunch line algorithm that contains parameters for bringing your lunch and multiple options available in the lunch line.

Example: Examine a set of block-based code and explain how abstraction was used.

Example: Use a block-based or script programming language

Step 1: Start

Step 2: Declare variables a, b and c.

Step 3: Read variables a, b and c.

Step 4: If a>b

        If a>c

            Display a is the largest number.

        Else

            Display c is the largest number.

  Else

        If b>c

            Display b is the largest number.

        Else

            Display c is the greatest number.

Step 5: Stop

Example: $3^8 = 3333333*3;$ =(Average) used in a spreadsheet to average a given list of grades.

Examples: Tradeoffs involving implementation, readability, and program performance.

Examples: All self-driving cars have a common goal of taking a passenger to a designation but may have different priorities such as safety, speed, or conservation; web search engines have their own algorithms for search with their own priorities.

Examples: Sorting, searching, shortest path, and data compression.
