Pre-lesson Preparation

Like all lessons on Eddy, this lesson follows a certain approach. If this is your first time implementing an Eddy lesson, check out our lesson approach for more information.

Prepare necessary technology/hardware in advance
- Devices (tablets/laptops/Chromebooks/computers) - one per team
- A stable wifi connection.
- Access to Pencil Code on each device.

Slide 3	Introduce the ground rules to learners. You can check out our lesson approach if it’s your first time conducting an Eddy lesson.
Slide 4	Define angle, degrees, and protractor using clear explanations and visual aids.
Slide 5	Ask the learners to open the game. Explain that they will be playing a game of guessing angles.
Slide 6	Begin by explaining the game rules located on the left side of the slide to the learners. Ensure that they understand the objective of the game and how it's played. Emphasize that the goal for each learner is to score 4-5 points in the game. Explain that they earn points by stopping the spinning circle at the correct angle value. Inform the learners that they have the option to play the game in pairs if they prefer.

What to do if the game doesn’t work properly?

Check internet connectivity, and browser compatibility, and ensure pop-up blockers are disabled. If the issue persists, have a backup game or activity ready, such as a paper-based angle estimation challenge.

How does the guessing game reinforce learning?

The guessing game reinforces learning by requiring students to apply their understanding of angle measurement, encouraging critical thinking, and improving their ability to estimate angles accurately.

How to make this activity challenging for advanced learners

For advanced learners, you can ask them to play the game at harder levels (level 3 or 4).

Slide 7,8,9	Introduce the different types(acute, obtuse, right, straight, reflex, and complete) angles to the learners.
Slide 10	Explain to the learners the step-by-step process to measure angles using a protractor.
Slide 11	Ask the learners to visit Geogebra. Encourage learners to begin by reading the instructions provided at the top of the Geogebra page. Encourage students to explore the tool, select different angles on the screen, and practice measuring them.
Slide 12	Introduce Pencil Code to the learners. Explain that Pencil Code is a digital tool akin to a virtual pencil used to create art on a computer through simple instructions. Highlight that learners can use Pencil Code to draw shapes, lines, patterns, and even design interactive elements.
Slide 13, 14	Guide learners on how to begin with Pencil Code. Ask them to explore the user interface.
Slide 15	Guide learners to create a circle segment using Pencil code by following the instructions. Introduce “for loops” to the learners. Ask them to create circles of different sizes and colors. Note: A "for loop" is like a repeating command in a computer program that helps it do something over and over again until a certain condition is met.
Slide 16	Challenge the learners to modify the code to create a square. Encourage them to think logically and figure out the correct approach.
Slide 17	Discuss the process of drawing a square using pencil code.
Slide 18	Define the "forever loop" as a repeating command in coding found under "control." Emphasize that it tells the computer to perform certain actions continuously. Explain the "random color function" located in "operators." Describe its purpose, which is to generate random colors in your code, making projects more visually dynamic.
Slide 19	Emphasize that learners should create unique artwork using whatever they learned during the lesson. Encourage them to experiment with variations like different shapes, angles, and diverse colors.

What if students face problems using Pencil Code?

Offer Support: Encourage them to seek assistance by raising their hand or approaching you.

Step-by-Step Guidance: Provide clear, step-by-step instructions to troubleshoot the issue.

Problem-Solving Approach: Guide them to identify the specific problem and think through possible solutions. Peer Collaboration: Encourage learners to collaborate with peers, fostering a cooperative learning environment.

How can I adjust this section for advanced learners?

Encourage advanced learners to experiment with multiple loops and patterns.

Slide 20, 21	Allow learners to share their creations. Briefly discuss the rules with the learners to be followed while sharing.
Slide 22	Reflection: Have learners reflect on their experience creating their art.
