Title: Computer Science Fundamentals Unit 3 Course B Lesson 1: Move It, Move It (2018)
URL: https://curriculum.code.org/csf-18/courseb/1/
Description:

This lesson will prepare students mentally for the coding exercises that they will encounter over the length of this course. In small teams, students will use physical activity to program their classmates to step carefully from place to place until a goal is achieved.

By using physical movement to program their classmates, students will run into issues and emotions similar to what they will feel when they begin coding on a computer. Encountering those stresses in a playful and open environment will help to alleviate intensity and allow students to practice necessary skills before they run into problems on their own.

Students will be able to:
- Define a list of steps (algorithm) to get a friend from their starting position to their goal.
- Translate a list of steps into a series of physical actions.
- Identify and fix errors in the execution of an algorithm.

Title: Computer Science Fundamentals Unit 3 Course B Lesson 8: My Loopy Robotic Friends Jr. (2018)
URL: https://curriculum.code.org/csf-18/courseb/8/
Description:

Building on the initial "My Robotic Friends" activity, students tackle larger and more complicated designs. In order to program their "robots" to complete these bigger designs, students will need to identify repeated patterns in their instructions that could be replaced with a loop.

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.

Description:

In this lesson, students continue learning the concept of loops. Here, Laurel the Adventurer uses loops to collect treasure in open cave spaces. A new `get treasure` block is introduced to help her on her journey.

This lesson gives students more practice with loops and encourages them to put multiple blocks inside of a `repeat`< as they try to collect as much treasure as possible.

Students will be able to:
- Identify the benefits of using a loop structure instead of manual repetition.
- Break down a long sequence of instructions into the smallest repeatable sequence possible.

Title: Computer Science Fundamentals Unit 3 Course B Lesson 11: Drawing Gardens with Loops (2018)
URL: https://curriculum.code.org/csf-18/courseb/11/
Description:

Students learn to draw images by looping simple sequences of instructions. In the previous online lesson, loops were used to traverse a maze and collect treasure. Here, students use loops to create patterns. At the end of this stage, students will be given the opportunity to create their own images using loops.

This lesson gives a different perspective on how loops can create things in programming. Students will test their critical thinking skills by evaluating given code and determining what needs to be added in order to solve the puzzle. Students can also reflect on the inefficiency of programming without loops here because of how many blocks the program would require without the help of `repeat` loops.

Students will be able to:
- Count the number of times an action should be repeated and represent it as a loop.
- Decompose a shape into its largest repeatable sequence.
- Create a program that draws complex shapes by repeating simple sequences.

Title: Computer Science Fundamentals Unit 3 Course B Lesson 12: The Big Event Jr. (2018)
URL: https://curriculum.code.org/csf-18/courseb/12/
Description:

Events are a great way to add variety to a pre-written algorithm. Sometimes you want your program to be able to respond to the user exactly when the user wants it to. That is what events are for in coding.

In this lesson, students will learn to distinguish events from actions. The students will see activities interrupted by having a "button" pressed on a paper remote. When seeing this event, the class will react with a unique action. Events are widely used in programming and should be easily recognizable after this lesson.

Students will be able to:

- Repeat commands given by an instructor.
- Recognize actions of the teacher as signals to initiate commands.
- Practice differentiating pre-defined actions and event-driven ones.
