Standard:
Model the way programs store data.

Descriptive Statement:
Information in the real world can be represented in computer programs. Students model the digital storage of data by transforming real-world information into symbolic representations that include text, numbers, and images. For example, after identifying symbols on a map and explaining what they represent in the real world, students could create their own symbols and corresponding legend to represent items on a map of their classroom (HSS.K.4.3, 1.2.3, 2.2.2) Alternatively, students could invent symbols to represent beat and/or pitch. Students could then modify symbols within the notation and explain how the musical phrase changes. (VAPA Music K.1.1, 1.1.1, 2.1.1, 2.2.2)

Standard:
Decompose the steps needed to solve a problem into a sequence of instructions.

Descriptive Statement:
Decomposition is the act of breaking down tasks into simpler tasks. For example, students could break down the steps needed to make a peanut butter and jelly sandwich, to brush their teeth, to draw a shape, to move a character across the screen, or to solve a level of a coding app. In a visual programming environment, students could break down the steps needed to draw a shape. (CA CCSS for Mathematics K.G.5, 1.G.1, 2.G.1) Alternatively, students could decompose the planning of a birthday party into tasks such as: 1) Decide when and where it should be, 2) List friends and family to invite, 3) Send the invitations, 4) Bake a cake, 5) Decorate, etc.

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)

Standard:
Store, copy, search, retrieve, modify, and delete information using a computing device, and define the information stored as data.

Descriptive Statement:
Information from the real world can be stored and processed by a computing device. When stored on a computing device, it is referred to as data. Data can include images, text documents, audio files, and video files. Students store, copy, search, retrieve, modify, and delete information using a computing device and define the information stored as data. For example, students could produce a story using a computing device, storing it locally or remotely (e.g., in the cloud). They could then make a copy of the story for peer revision and editing. When the final copy of the story is complete, students delete any unnecessary files. They search for and retrieve data from a local or remote source, depending on where it was stored. (CA CCSS for ELA/Literacy W.K.6, W.K.5, W1.6, W.1.5, W.2.6, W.2.5) Alternatively, students could record their voices singing an age-appropriate song. They could store the data on a computing device, search for peers' audio files, retrieve their own files, and delete unnecesary takes. (VAPA Music K.2.2, 1.2.2, 2.2.2)

Standard:
Model and describe how people connect to other people, places, information and ideas through a network.

Descriptive Statement:
Information is passed between multiple points (nodes) on a network. The Internet is a network that enables people to connect with other people worldwide through many different points of connection. Students model ways that people communicate, find information, or acquire ideas through a network. Students use a network, such as the internet, to access information from multiple locations or devices. For example, students could utilize a cloud-based platform to access shared documents or note-taking applications for group research projects, and then create a model (e.g., flowchart) to illustrate how this network aids collaboration. (CA CCSS for ELA/Literacy W.K.7, W.1.7, W.2.7) Alternatively, students could design devices that use light or sound to aid communication across distances (e.g., light source to send signals, paper cup and string “telephones,” and a pattern of drum beats) and then describe how networks build connections. (CA NGSS: 1-PS4-4)

Standard:
Create programs that use variables to store and modify data.

Descriptive Statement:
Variables are used to store and modify data. Students use variables in programs they create. At this level, students may need guidance in identifying when to create variables (i.e., performing the abstraction). For example, students could create a game to represent predators and prey in an ecosystem. They could declare a "score" variable, assign it to 0 at the start of the game, and add 1 (increment) the score each time the predator captures its prey. They could also declare a second "numberOfLives" variable, assign it to 3 at the start of the game, and subtract 1 (decrement) each time a prey is captured. They could program the game to end when "numberOfLives" equals 0. (CA NGSS: 5-LS2-1) (CA CCSS for Mathematics 5.OA.3) Alternatively, when students create programs to draw regular polygons, they could use variables to store the line size, line color, and/or side length. Students can extend learning by creatively combining a variety of polygons to create digital artwork, comparing and contrasting this to another work of art made by the use of different art tools and media, such as watercolor or tempera paints. (CA CCSS for Mathematics 3.G.1) (VAPA Visual Arts 3.1.4)

Standard:
Decompose problems into smaller, manageable tasks which may themselves be decomposed.

Descriptive Statement:
Decomposition is the act of breaking down tasks into simpler tasks. This manages complexity in the problem solving and program development process. For example, students could create an animation to represent a story they have written. Students write a story and then break it down into different scenes. For each scene, they would select a background, place characters, and program actions in that scene. (CA CCSS for ELA/Literacy W.3.3, W.4.3, W.5.3) Alternatively, students could create a program to allow classmates to present data collected in an experiment. For example, if students collected rain gauge data once per week for 3 months, students could break down the program tasks: 1) ask the user to input 12 weeks' worth of data, 2) process the data (e.g., add the first four entries to calculate the rain amount for month 1, convert to metric system measurements), and 3) direct the creation or resizing of objects (e.g., one rectangular chart bar for each month) to represent the total number of rainfall for that month. (CA NGSS: 3-ETS-1-2) (CA CCSS for Mathematics 3.MD.2)

Standard:
Create programs by incorporating smaller portions of existing programs, to develop something new or add more advanced features.

Descriptive Statement:
Programs can be broken down into smaller parts, which can be incorporated into new or existing programs. Students incorporate predefined functions into their original designs. At this level, students do not need to understand all of the underlying implementation details of the abstractions that they use. For example, students could use code from a ping pong animation to make a ball bounce in a new basketball game. They could also incorporate code from a single-player basketball game to create a two-player game with slightly different rules. Alternatively, students could remix an animated story and add their own conclusion and/or additional dialogue. (CA CCSS for ELA/Literacy W.3.3.B, W.3.3.D, W.4.3.B, W.4.3.E, W.5.3.B, W.5.3.E) Additionally, when creating a game that occurs on the moon or planets, students could incorporate and modify code that simulates gravity on Earth. They could modify the strength of the gravitational force based on the mass of the planet or moon. (CA NGSS: 5-PS2-1)

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. (CA NGSS: 4-LS1-2)

Standard:
Explain that the amount of space required to store data differs based on the type of data and/or level of detail.

Descriptive Statement:
All saved data requires space to store it, whether locally or not (e.g., on the cloud). Music, images, video, and text require different amounts of storage. Video will often require more storage and different format than music or images alone because video combines both. The level of detail represented by that data also affects storage requirements. For instance, two pictures of the same object can require different amounts of storage based upon their resolution, and a high-resolution photo could require more storage than a low-resolution video. Students select appropriate storage for their data. For example, students could create an image using a standard drawing app. They could save the image in different formats (e.g., .png, .jpg, .pdf) and compare file sizes. They should also notice that different file sizes can result in differences in quality or resolution (e.g., some pictures could be more pixelated while some could be sharper). Alternatively, in an unplugged activity, students could represent images by coloring in squares within a large grid. They could model how a larger grid requires more storage but also represents a clearer image (i.e., higher resolution).
