Standard:
Create programs with sequences of commands and simple loops, to express ideas or address a problem.
Descriptive Statement:
People create programs by composing sequences of commands that specify the precise order in which instructions should be executed. Loops enable programs to repeat a sequence of commands multiple times. For example, students could follow simple movements in response to oral instructions. Students could then create a simple sequence of movement commands in response to a given problem (e.g., In how many ways can you travel from point A to point B?) and represent it as a computer program, using loops to repeat commands. (VAPA Dance K.1.4, 1.2.3, 1.2.5, 1.2.8, 2.2.1, 2.2.2, 2.2.3) Alternatively, on a mat with many different CVC words, students could program robots to move to words with a similar vowel sound. Students could look for multiple ways to solve the problem and simplify their solution by incorporating loops. (CA CCSS for ELA/Literacy RF.K.2.D, RF.1.2.C)

Communicating About Computing (7.2)
Standard:
Explain the functions of common hardware and software components of computing systems.
Descriptive Statement:
A computing system is composed of hardware and software. Hardware includes the physical components of a computer system. Software provides instructions for the system. These instructions are represented in a form that a computer can understand and are designed for specific purposes. Students identify and describe the function of hardware, such as desktop computers, laptop computers, tablet devices, monitors, keyboards, mice, trackpads, microphones, and printers. Students also identify and describe common software applications such as web browsers, games, and word processors. For example, students could create drawings of a computing system and label its major components with appropriate terminology. Students could then explain the function of each component. (VAPA Visual Arts 2 5.0) (CA CCSS for ELA/Literacy SL.K.5, SL.K.6, SL.1.5, SL.1.6, SL.2.5, SL.2.6) Alternatively, students could each be assigned a component of a computing system and arrange their bodies to represent the system. Students could then describe how their assigned component functions within the system. (P.E.K.1, 1.1)

Practice(s):
Creating Computational Artifacts (5.2)
Standard:
Create programs that include events, loops, and conditionals.
Descriptive Statement:
Control structures specify the order (sequence) in which instructions are executed within a program and can be combined to support the creation of more complex programs. Events allow portions of a program to run based on a specific action. Conditionals allow for the execution of a portion of code in a program when a certain condition is true. Loops allow for the repetition of a sequence of code multiple times. For example, students could program an interactive map of the United States of America. They could use events to initiate a question when the user clicks on a state and conditionals to check whether the user input is correct. They could use loops to repeat the question until the user answers correctly or to control the length of a "congratulations" scenario that plays after a correct answer. (HSS.5.9) Alternatively, students could write a math fluency game that asks products of two one-digit numbers and then uses a conditional to check whether or not the answer that was entered is correct. They could use a loop to repeatedly ask another question. They could use events to allow the user to click on a green button to play again or a red button to end the game. (CA CCSS for Mathematics 3.OA.7) Additionally, students could create a program as a role-playing game based on a literary work. Loops could be used to animate a character's movement. When reaching a decision point in the story, an event could initiate the user to type a response. A conditional could change the setting or have the story play out differently based on the user input. (CA CCSS for ELA/Literacy RL.5.3)

Developing and Using Abstractions (4.4)
Standard:
Demonstrate how computer hardware and software work together as a system to accomplish tasks.
Descriptive Statement:
Hardware and software are both needed to accomplish tasks with a computing device. Students create a model to illustrate ways in which hardware and software work as a system. Students could draw a model on paper or in a drawing program, program an animation to demonstrate it, or demonstrate it by acting this out in some way. At this level, a model should only include the basic elements of a computer system, such as input, output, processor, sensors, and storage. For example, students could create a diagram or flow chart to indicate how a keyboard, desktop computer, monitor, and word processing software interact with each other. The keyboard (hardware) detects a key press, which the operating system and word processing application (software) displays as a new character that has been inserted into the document and is visible through the monitor (hardware). Students could also create a model by acting out the interactions of these different hardware and software components. Alternatively, when describing that animals and people receive different types of information through their senses, process the information in their brain, and respond to the information in different ways, students could compare this to the interaction of how the information traveling through a computer from mouse to processor are similar to signals sent through the nervous system telling our brain about the world around us to prompt responses.

Creating Computational Artifacts (5.1, 5.2)
Standard:
Design and iteratively develop programs that combine control structures and use compound conditions.
Descriptive Statement:
Control structures can be combined in many ways. Nested loops are loops placed within loops, and nested conditionals allow the result of one conditional to lead to another. Compound conditions combine two or more conditions in a logical relationship (e.g., using AND, OR, and NOT). Students appropriately use control structures to perform repetitive and selection tasks. For example, when programming an interactive story, students could use a compound conditional within a loop to unlock a door only if a character has a key AND is touching the door. (CA CCSS for ELA/Literacy W.6.3, W.7.3, W.8.3) Alternatively, students could use compound conditionals when writing a program to test whether two points lie along the line defined by a particular linear function. (CA CCSS for Mathematics 8.EE.7) Additionally, students could use nested loops to program a character to do the "chicken dance" by opening and closing the beak, flapping the wings, shaking the hips, and clapping four times each; this dance "chorus" is then repeated several times in its entirety.

Creating Computational Artifacts (5.1)
Standard:
Design a project that combines hardware and software components to collect and exchange data.
Descriptive Statement:
Collecting and exchanging data involves input, output, storage, and processing. When possible, students select the components for their project designs by considering tradeoffs between factors such as functionality, cost, size, speed, accessibility, and aesthetics. Students do not need to implement their project design in order to meet this standard. For example, students could design a mobile tour app that displays information relevant to specific locations when the device is nearby or when the user selects a virtual stop on the tour. They select appropriate components, such as GPS or cellular-based geolocation tools, textual input, and speech recognition, to use in their project design. Alternatively, students could design a project that uses a sensor to collect the salinity, moisture, and temperature of soil. They may select a sensor that connects wirelessly through a Bluetooth connection because it supports greater mobility, or they could instead select a physical USB connection that does not require a separate power source. (CA NGSS: MS-ETS1-1, MS-ETS1-2)

Creating Computational Artifacts (5.2)
Standard:
Justify the selection of specific control structures by identifying tradeoffs associated with implementation, readability, and performance.
Descriptive Statement:
The selection of control structures in a given programming language impacts readability and performance. Readability refers to how clear the program is to other programmers and can be improved through documentation. Control structures at this level may include, for example, conditional statements, loops, event handlers, and recursion. Students justify control structure selection and tradeoffs in the process of creating their own computational artifacts. The discussion of performance is limited to a theoretical understanding of execution time and storage requirements; a quantitative analysis is not expected. For example, students could compare the readability and program performance of iterative and recursive implementations of procedures that calculate the Fibonacci sequence. Alternatively, students could compare the readability and performance tradeoffs of multiple if statements versus a nested if statement.

Creating Computational Artifacts (5.1, 5.2, 5.3)
Standard:
Iteratively design and develop computational artifacts for practical intent, personal expression, or to address a societal issue by using events to initiate instructions.
Descriptive Statement:
In this context, relevant computational artifacts can include programs, mobile apps, or web apps. Events can be user-initiated, such as a button press, or system-initiated, such as a timer firing. For example, students might create a tool for drawing on a canvas by first implementing a button to set the color of the pen. Alternatively, students might create a game where many events control instructions executed (e.g., when a score climbs above a threshold, a congratulatory sound is played; when a user clicks on an object, the object is loaded into a basket; when a user clicks on an arrow key, the player object is moved around the screen).

Developing and Using Abstractions (4.1)
Standard:
Compare levels of abstraction and interactions between application software, system software, and hardware.
Descriptive Statement:
At its most basic level, a computer is composed of physical hardware on which software runs. Multiple layers of software are built upon various layers of hardware. Layers manage interactions and complexity in the computing system. System software manages a computing device's resources so that software can interact with hardware. Application software communicates with the user and the system software to accomplish its purpose. Students compare and describe how application software, system software, and hardware interact. For example, students could compare how various levels of hardware and software interact when a picture is to be taken on a smartphone. Systems software provides low-level commands to operate the camera hardware, but the application software interacts with system software at a higher level by requesting a common image file format (e.g., .png) that the system software provides.

Recognizing and Defining Computational Problems, Communicating About Computing (3.2, 7.2)
Standard:
Demonstrate the flow of execution of a recursive algorithm.
Descriptive Statement:
Recursion is a powerful problem-solving approach where the problem solution is built on solutions of smaller instances of the same problem. A base case, which returns a result without referencing itself, must be defined, otherwise infinite recursion will occur. Students represent a sequence of calls to a recursive algorithm and show how the process resolves to a solution. For example, students could draw a diagram to illustrate flow of execution by keeping track of parameter and returned values for each recursive call. Alternatively, students could create a video showing the passing of arguments as the recursive algorithm runs.
