Standard Identifier: K-2.DA.7

Grade Range: K–2
Concept: Data & Analysis
Subconcept: Storage
Practice(s): Developing and Using Abstractions (4.2)

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 Identifier: K-2.DA.9

Grade Range: K–2
Concept: Data & Analysis
Subconcept: Inference & Models
Practice(s): Developing and Using Abstractions (4.1)

Standard:
Identify and describe patterns in data visualizations, such as charts or graphs, to make predictions.

Descriptive Statement:
Data can be used to make inferences or predictions about the world. For example, students could record the number of each color of candy in a small packet. Then, they compare their individual data with classmates. Students could use the collected data to predict how many of each colored candy will be in a full size bag of like candy. (CA CCSS for Mathematics K.MD.3, 1.MD.4, 2.MD.10) Alternatively, students could sort and classify objects according to their properties and note observations. Students could then create a graph or chart of their observations and look for connections/relationships (e.g., items that are hard are usually also smooth, or items that are fluffy are usually also light in weight.) Students then look at pictures of additional objects and make predictions regarding the properties of the objects pictured. (CA NGSS: 2-PS1-1, 2-PS1-2)

Standard Identifier: K-2.IC.19

Grade Range: K–2
Concept: Impacts of Computing
Subconcept: Social Interactions
Practice(s): Collaborating Around Computing (2.1)

Standard:
Work respectfully and responsibly with others when communicating electronically.

Descriptive Statement:
Electronic communication facilitates positive interactions, such as sharing ideas with many people, but the public and anonymous nature of electronic communication also allows intimidating and inappropriate behavior in the form of cyberbullying. Responsible electronic communication includes limiting access to personably identifiable information. Students learn and use appropriate behavior when communicating electronically (often called "netiquette"). For example, students could share their work on a classroom blog or in other collaborative spaces online, taking care to avoid sharing information that is inappropriate or that could personally identify themselves to others. (CA CCSS for ELA/Literacy W.K.6, W.1.6, W.21.6) Alternatively, students could provide feedback to others on their work in a kind and respectful manner. They could learn how written words can be easily misinterpreted and may seem negative when the intention may be to express confusion, give ideas, or prompt further discussion. They could also learn to identify harmful behavior on collaborative spaces and intervening to find the proper authority to help. (CA CCSS for ELA/Literacy W.K.5, W.1.5, W.2.5) (HSS 1.1.2)

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. (CA CCSS for ELA/Literacy SL.K.1, SL.1.1, SL 2.1, W.1.1, W.2.1)

Standard Identifier: K-2.NI.6

Grade Range: K–2
Concept: Networks & the Internet
Subconcept: Cybersecurity
Practice(s): Developing and Using Abstractions (4.4)

Standard:
Create patterns to communicate a message.

Descriptive Statement:
Connecting devices to a network or the Internet provides great benefit, but care must be taken to protect devices and information from unauthorized access. Messages can be protected by using secret languages or codes. Patterns help to ensure that the intended recipient can decode the message. Students create a pattern that can be decoded and translated into a message. For example, students could use a table to associate each text character with a number. Then, they could select a combination of text characters and use mathematical functions (e.g., simple arithmetic operations) to transform the numbers associated with the characters into a secret message. Using inverse functions, a peer could translate the secret message back into its original form. (CA CCSS for Mathematics 2.OA.A.1, 2.OA.B.2) Alternatively, students could use icons or invented symbols to represent patterns of beat, rhythm, or pitch to decode a musical phrase. (VAPA Music K.1.1, 1.1.1, 2.1.1, 2.2.2)

Standard Identifier: 3-5.DA.7

Grade Range: 3–5
Concept: Data & Analysis
Subconcept: Storage
Practice(s): Developing and Using Abstractions (4.2)

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).

Standard Identifier: 3-5.DA.9

Grade Range: 3–5
Concept: Data & Analysis
Subconcept: Inference & Models
Practice(s): Communicating About Computing (7.1)

Standard:
Use data to highlight and/or propose relationships, predict outcomes, or communicate ideas.

Descriptive Statement:
The accuracy of data analysis is related to how the data is represented. Inferences or predictions based on data are less likely to be accurate if the data is insufficient, incomplete, or inaccurate or if the data is incorrect in some way. Additionally, people select aspects and subsets of data to be transformed, organized, and categorized. Students should be able to refer to data when communicating an idea, in order to highlight and/or propose relationships, predict outcomes, highlight different views and/or communicate insights and ideas. For example, students can be provided a scenario in which they are city managers who have a specific amount of funds to improve a city in California. Students can collect data of a city concerning land use, vegetation, wildlife, climate, population density, services and transportation (HSS.4.1.5) to determine and present what area needs to be focused on to improve a problem. Students can compare their data and planned use of funds with peers, clearly communicating or predict outcomes based on data collected. (CA CCCS for ELA/Literacy SL.3.1, SL.4.1, SL.5.1) Alternatively, students could record the temperature at noon each day to show that temperatures are higher in certain months of the year. If temperatures are not recorded on non-school days or are recorded incorrectly, the data would be incomplete and ideas being communicated could be inaccurate. Students may also record the day of the week on which the data was collected, but this would have no relevance to whether temperatures are higher or lower. In order to have sufficient and accurate data on which to communicate the idea, students might use data provided by a governmental weather agency. (CA NGSS: 3-ESS2-1)

Standard Identifier: 3-5.IC.22

Grade Range: 3–5
Concept: Impacts of Computing
Subconcept: Social Interactions
Practice(s): Fostering an Inclusive Computing Culture (1.1)

Standard:
Seek and explain the impact of diverse perspectives for the purpose of improving computational artifacts.

Descriptive Statement:
Computing technologies enable global collaboration and sharing of ideas. Students solicit feedback from a diverse group of users and creators and explain how this input improves their computational artifacts. For example, students could seek feedback from classmates via user surveys, in order to create an idea and then make a claim as to how to improve the overall structure and function of their computational artifact. Using the feedback students could write an opinion piece supporting their claim. (CA CCSS for ELA/Literacy W.3.1, W.4.1, W.5.1) Alternatively, with guidance from their teacher, students could use video conferencing tools, shared documents, or other online collaborative spaces, such as blogs, wikis, forums, or website comments, to gather and synthesize feedback from individuals and groups about programming projects. (CA CCSS for ELA/Literacy SL.3.1, SL.4.1, SL.5.1)

Standard Identifier: 3-5.NI.5

Grade Range: 3–5
Concept: Networks & the Internet
Subconcept: Cybersecurity
Practice(s): Recognizing and Defining Computational Problems (3.1)

Standard:
Describe physical and digital security measures for protecting personal information.

Descriptive Statement:
Personal information can be protected physically and digitally. Cybersecurity is the protection from unauthorized use of electronic data, or the measures taken to achieve this. Students identify what personal information is and the reasons for protecting it. Students describe physical and digital approaches for protecting personal information such as using strong passwords and biometric scanners. For example, students could engage in a collaborative discussion orally or in writing regarding topics that relate to personal cybersecurity issues. Discussion topics could be based on current events related to cybersecurity or topics that are applicable to students, such as the necessity of backing up data to guard against loss, how to create strong passwords and the importance of not sharing passwords, or why we should keep operating systems updated and use anti-virus software to protect data and systems. Students could also discuss physical measures that can be used to protect data including biometric scanners, locked doors, and physical backups. (CA CCSS for ELA/Literacy SL.3.1, SL.4.1, SL.5.1)

Standard Identifier: 3-5.NI.6

Grade Range: 3–5
Concept: Networks & the Internet
Subconcept: Cybersecurity
Practice(s): Developing and Using Abstractions (4.4)

Standard:
Create patterns to protect information from unauthorized access.

Descriptive Statement:
Encryption is the process of converting information or data into a code, especially to prevent unauthorized access. At this level, students use patterns as a code for encryption, to protect information. Patterns should be decodable to the party for whom the message is intended, but difficult or impossible for those with unauthorized access. For example, students could create encrypted messages via flashing a flashlight in Morse code. Other students could decode this established language even if it wasn't meant for them. To model the idea of protecting data, students should create their own variations on or changes to Morse code. This ensures that when a member of that group flashes a message only other members of their group can decode it, even if other students in the room can see it. (CA NGSS: 4-PS4-3) Alternatively, students could engage in a CS Unplugged activity that models public key encryption: One student puts a paper containing a written secret in a box, locks it with a padlock, and hands the box to a second student. Student 2 puts on a second padlock and hands it back. Student 1 removes her lock and hands the box to student 2 again. Student 2 removes his lock, opens the box, and has access to the secret that student 1 sent him. Because the box always contained at least one lock while in transit, an outside party never had the opportunity to see the message and it is protected.
