Standard Identifier: K-2.IC.20

Grade Range: K–2
Concept: Impacts of Computing
Subconcept: Safety, Law, & Ethics
Practice(s): Recognizing and Defining Computational Problems (3.1)

Standard:
Describe approaches and rationales for keeping login information private, and for logging off of devices appropriately.

Descriptive Statement:
People use computing technology in ways that can help or hurt themselves and/or others. Harmful behaviors, such as sharing passwords or other private information and leaving public devices logged in should be recognized and avoided. Students keep login information private, log off of devices appropriately, and discuss the importance of these practices. For example, while learning about individual responsibility and citizenship, students could create a "privacy folder" to store login information, and keep this folder in a secure location that is not easily seen and accessed by classmates. Students could discuss the relative benefits and impacts of choosing to store passwords in a folder online versus on paper. They could also describe how using the same login and password across many systems and apps could lead to significant security issues and requires even more vigilance in maintaining security. (HSS K.1) Alternatively, students can write an informational piece regarding the importance of keeping login information private and logging off of public devices. (CA CCSS for ELA/Literacy W.K.2, W.1.2, W.2.2)

Standard Identifier: K-2.NI.5

Grade Range: K–2
Concept: Networks & the Internet
Subconcept: Cybersecurity
Practice(s): Communicating About Computing (7.2)

Standard:
Explain why people use passwords.

Descriptive Statement:
Passwords protect information from unwanted use by others. When creating passwords, people often use patterns of familiar numbers and text to more easily remember their passwords. However, this may make the passwords weaker. Knowledge about the importance of passwords is an essential first step in learning about cybersecurity. Students explain that strong passwords are needed to protect devices and information from unwanted use. For example, students could play a game of guessing a three-character code. In one version of the game, the characters are only numbers. In the second version, characters are numbers or letters. Students describe why it would take longer to guess the correct code in the second case. Alternatively, students could engage in a collaborative discussion regarding passwords and their importance. Students may follow-up the discussion by exploring strong password components (combination of letters, numbers, and characters), creating their own passwords, and writing opinion pieces indicating reasons their passwords are strong.

Standard Identifier: 3-5.AP.10

Grade Range: 3–5
Concept: Algorithms & Programming
Subconcept: Algorithms
Practice(s): Recognizing and Defining Computational Problems, Testing and Refining Computational Artifacts (3.3, 6.3)

Standard:
Compare and refine multiple algorithms for the same task and determine which is the most appropriate.

Descriptive Statement:
Different algorithms can achieve the same result, though sometimes one algorithm might be more appropriate for a specific solution. Students examine different ways to solve the same task and decide which would be the better solution for the specific scenario. For example, students could use a map and create multiple algorithms to model the early land and sea routes to and from European settlements in California. They could then compare and refine their algorithms to reflect faster travel times, shorter distances, or avoid specific characteristics, such as mountains, deserts, ocean currents, and wind patterns. (HSS.4.2.2) Alternatively, students could identify multiple algorithms for decomposing a fraction into a sum of fractions with the same denominator and record each decomposition with an equation (e.g., 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8). Students could then select the most efficient algorithm (e.g., fewest number of steps). (CA CCSS for Mathematics 4.NF.3b) Additionally, students could compare algorithms that describe how to get ready for school and modify them for supporting different goals including having time to care for a pet, being able to talk with a friend before classes start, or taking a longer route to school to accompany a younger sibling to their school first. Students could then write an opinion piece, justifying with reasons their selected algorithm is most appropriate. (CA CCSS for ELA/Literacy W.3.1, W.4.1, W.5.1)

Standard Identifier: 3-5.AP.13

Grade Range: 3–5
Concept: Algorithms & Programming
Subconcept: Modularity
Practice(s): Recognizing and Defining Computational Problems (3.2)

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 Identifier: 3-5.AP.16

Grade Range: 3–5
Concept: Algorithms & Programming
Subconcept: Program Development
Practice(s): Creating Computational Artifacts, Communicating About Computing (5.2, 7.3)

Standard:
Observe intellectual property rights and give appropriate attribution when creating, remixing, or combining programs.

Descriptive Statement:
Intellectual property rights can vary by country, but copyright laws give the creator of a work a set of rights and prevents others from copying the work and using it in ways that they may not like. Students consider common licenses that place limitations or restrictions on the use of others' work, such as images and music downloaded from the Internet. When incorporating the work of others, students attribute the work. At this level, students could give attribution by including credits or links directly in their programs, code comments, or separate project pages. For example, when making a program to model the life cycle of a butterfly, students could modify and reuse an existing program that describes the life cycle of a frog. Based on their research, students could identify and use Creative Commons-licensed or public domain images and sounds of caterpillars and butterflies. Students give attribution by properly citing the source of the original piece as necessary. (CA NGSS: 3-LS-1-1) (CA CCSS for ELA/Literacy W.3.8, W.4.8, W.5.8) Alternatively, when creating a program explaining the structure of the United States goverment, students find Creative Commons-licensed or public domain images to represent the three branches of government and attribute ownership of the images appropriately. If students find and incorporate an audio file of a group playing part of the national anthem, they appropriately give attribution on the project page. (HSS.3.4.4)

Standard Identifier: 3-5.AP.17

Grade Range: 3–5
Concept: Algorithms & Programming
Subconcept: Program Development
Practice(s): Testing and Refining Computational Artifacts (6.2)

Standard:
Test and debug a program or algorithm to ensure it accomplishes the intended task.

Descriptive Statement:
Programs do not always run properly. Students need to understand how to test and make necessary corrections to their programs to ensure they run properly. Students successfully identify and fix errors in (debug) their programs and programs created by others. Debugging strategies at this level may include testing to determine the first place the solution is in error and fixing accordingly, leaving "breadcrumbs" in a program, and soliciting assistance from peers and online resources. For example, when students are developing a program to control the movement of a robot in a confined space, students test various inputs that control movement of the robot to make sure it behaves as intended (e.g., if an input would cause the robot to move past a wall of the confined space, it should not move at all). (CA NGSS: 3-5-ETS1-3) Additionally, students could test and debug an algorithm by tracing the inputs and outputs on a whiteboard. When noticing "bugs" (errors), students could identify what was supposed to happen and step through the algorithm to locate and then correct the error.

Standard Identifier: 3-5.AP.19

Grade Range: 3–5
Concept: Algorithms & Programming
Subconcept: Program Development
Practice(s): Communicating About Computing (7.2)

Standard:
Describe choices made during program development using code comments, presentations, and demonstrations.

Descriptive Statement:
People communicate about their code to help others understand and use their programs. Explaining one's design choices gives others a better understanding of one's work. Students may explain their step-by-step process of creating a program in a presentation or demonstration of their personal code journals. They describe how comments within code organize thought and process during the develpment of the program. For example, students could describe the decision to have the score in a game flash when it can be rounded to 100 by writing a comment in the code. (CA CCSS for Mathematics 3.NBT.1) Alternatively, students could present their overall program development experience and justify choices made by using storyboards, annotated images, videos, and/or journal entries. (CA CCSS for ELA/Literacy SL.3.4, SL.4.4, SL.5.4, SL.3.5, SL.4.5, SL.5.5) (CA NGSS: 3-5-ETS1-1, 3.5-ETS1-2, 3.5-ETS1-3)

Standard Identifier: 3-5.CS.1

Grade Range: 3–5
Concept: Computing Systems
Subconcept: Devices
Practice(s): Communicating About Computing (7.2)

Standard:
Describe how computing devices connect to other components to form a system.

Descriptive Statement:
Computing devices often depend on other devices or components. Students describe physical and wireless connections to other components, including both input devices (e.g., keyboards, sensors, remote controls, microphones) and output devices (e.g., 3D printers, monitors, speakers). For example, students could describe the relationship among the heart, lungs, muscles, blood, and oxygen during physical activity and then compare this to how a mouse, keyboard, printer, and desktop computer connect and interact to allow for input, processing, and output. (P.E.3.4.7) Alternatively, when describing how light reflected from objects enters the eye and is then transferred to the brain to construct a visual image, students could compare this to a computing system that uses programming to construct a visual image when data is transferred and constructed/reconstructed through a keyboard, camera, or other components. (CA NGSS: 4-PS4-2)

Standard Identifier: 3-5.CS.3

Grade Range: 3–5
Concept: Computing Systems
Subconcept: Troubleshooting
Practice(s): Testing and Refining Computational Artifacts (6.2)

Standard:
Determine potential solutions to solve simple hardware and software problems using common troubleshooting strategies.

Descriptive Statement:
Although computing systems vary, common troubleshooting strategies can be used across many different systems. Students use troubleshooting strategies to identify problems that could include a device not responding, lacking power, lacking a network connection, an app crashing, not playing sounds, or password entry not working. Students use and develop various solutions to address these problems. Solutions may include rebooting the device, checking for power, checking network availability, opening and closing an app, making sure speakers are turned on or headphones are plugged in, and making sure that the caps lock key is not on. For example, students could prepare for and participate in a collaborative discussion in which they identify and list computing system problems and then describe common successful fixes. (CA CCSS for ELA/Literacy SL.3.1, SL.4.1, SL.5.1) Alternatively, students could write informative/explanatory texts, create a poster, or use another medium of communication to examine common troubleshooting strategies and convey these ideas and information clearly. (CA CCSS for ELA/Literacy W.3.2, W.4.2, W.5.2)

Standard Identifier: 3-5.DA.8

Grade Range: 3–5
Concept: Data & Analysis
Subconcept: Collection, Visualization, & Transformation
Practice(s): Communicating About Computing (7.1)

Standard:
Organize and present collected data visually to highlight relationships and support a claim.

Descriptive Statement:
Raw data has little meaning on its own. Data is often sorted or grouped to provide additional clarity. Organizing data can make interpreting and communicating it to others easier. Data points can be clustered by a number of commonalities. The same data could be manipulated in different ways to emphasize particular aspects or parts of the data set. For example, students could create and administer electronic surveys to their classmates. Possible topics could include favorite books, family heritage, and after school activities. Students could then create digital displays of the data they have collected such as column histogram charts showing the percent of respondents in each grade who selected a particular favorite book. Finally, students could make quantitative statements supported by the data such as which books are more appealing to specific ages of students. As an extension, students could write an opinion piece stating a claim and supporting it with evidence from the data they collected. (CA CCSS for Mathematics 3.MD.3, 4.MD.4, 5.MD.2) (CA CCSS for ELA/Literacy W.3.1, W.4.1, W.5.1) Alternatively, students could represent data in tables and graphical displays to describe weather experienced in the last several years. They could select the type of graphical display based on the specific data represented (e.g., daily high/low temperatures on a scatter plot, average temperatures for a month across years in a column chart). Students could then make a claim about expected weather in future months based on the data. (CA NGSS: 3-ESS2-1)
