Title: Scytale Messages
URL: https://aptv.pbslearningmedia.org/resource/arct14.math.zscytale/scytale-messages/
Description:

Make a coded message called a scytale message to send to a friend. This activity from Zoom focuses on your ability to follow directions and requires a cylinder. This learning activity can be used during a lesson on encryption.

Subject: Digital Literacy and Computer Science (5)
Title: Computer Science Fundamentals Unit 7 Course F Lesson 5: Creating Art With Code (2018)
URL: https://curriculum.code.org/csf-18/coursef/5/
Description:

In this lesson, students will take control of the Artist to complete drawings on the screen. This Artist stage will allow students to create images of increasing complexity using new blocks like `move forward by 100 pixels` and `turn right by 90 degrees`.

Building off of the students' previous experience with sequencing, this lesson will work to inspire more creativity with coding. The purpose of this lesson is to solidify knowledge of sequencing by introducing new blocks and goals. In this case, students learn more about pixels and angles using the new blocks, while still practicing their sequencing skills. Also, students will be able to visualize new goals such as coding the Artist to draw a square.

Students will be able to:
- create a program to complete an image using sequential steps.
- break complex shapes into simple parts.

Title: Computer Science Fundamentals Unit 7 Course F Lesson 6: My Loopy Robotic Friends (2018)
URL: https://curriculum.code.org/csf-18/coursef/6/
Description:

Building on the initial "My Robotic Friends" activity, students learn to use loops when programming their robots in order to build bigger structures more efficiently.

This lesson serves as a reintroduction to loops, using the now-familiar set of "robot" programming instructions. Students will develop critical thinking skills by looking for patterns of repetition in the movements of classmates and determining how to simplify those repeated patterns using loops.

Students will be able to:
- identify repeated patterns in code that could be replaced with a loop.
- write instructions that use loops to repeat patterns.
