Abstract
The eighth to tenth graders/Year 8-10 students demonstrate their learning and understanding through their comprehension of 2-dimensional and 3-dimensional shapes. Since students already learned and had a foundation of 2-dimensional shapes during their sixth or seventh grade, they will explore their fundamental knowledge of 2-dimensional shapes by reviewing the concepts and practicing in Khan Academy, and they also will use the online platform to construct simple and complicated 2-dimensional polygons. Moreover, they will discover the 3-dimensional shapes through reading, watching videos, and practicing in Khan Academy. They also investigate the differences between the 2-dimensional and 3-dimensional shapes by comparing and contrasting them. In addition, they will express what they have been learned and understood through various assessments and hands-on projects. Therefore, students will be able to comprehend their knowledge of 2-dimensional and 3-dimensional shapes.

The Teacher will need:
Learning Intention: I can describe what I learned and understood through these updates and determine which other areas I still need to improve.
Take this survey to check your learning and understanding of 2-dimensional and 3-dimensional shapes
In case some of you might not be able to open the survey link, the pictures shown below my survey questions. You can answer those questions and send your answers to me through email.
Purpose: Students will be able to express what they learned and understood through previous updates.
The Teacher will need:
Learning Intention: I can construct shapes and use them to illustrate my project.
Everyone needs to create a short video that will explain the ideas and concepts you have learned while studying the unit on the 2-dimensional and 3-dimensional shapes. As you proceed through the unit, you will be asked to complete sections of this project that relate to each new concept covered. You can add your notes to sections in the Structure Tool in Creator in Scholar. You can then elaborate on these to create your final video for submission.
Requirements:
1. The video must be more than 5 minutes in length (no maximum time limitation).
2. All concepts and scenes covered must be included.
3. You must spend at least 1 minute discussing the importance of 2-dimensional and 3-dimensional shapes.
Check your Notifications for a "Work Request". This will take you into Scholar where you can start your work. Look at the Rubric to see what is expected of you. Use the Structure Tool to create five sections for your work.
Start with Scene 1: Explain what, how, and where you found your materials (due to COVID-19 stay home learning situation) to construct your shapes, and also provide a short description of your imaginary shapes.
Scene 2: Demonstrate how you are going to use the materials to construct your shape, and please also show detailed guidelines and explanations while recording the video.
Scene 3: Describe how you will use it in your life.
Scene 4: Ask other people for their comments/reviews/opinions about your shape
Scene 5: Express your final thought of completing this project and your reflection of this project.
Rubrics:
Purpose: Students will be able to construct 3-dimensional shapes with supplies and illustrate the detailed progress of the project.
As part of the assessment for this Learning Module, students will create videos in which they explain each of the major concepts covered and then discuss the importance of knowing and understanding the 2-dimensional and 3-dimensional shapes. Every student should add to their project in Scholar as they progress through the Learning Module, even though they are creating one video together.
When setting up the project settings in Scholar, manually assign one reviewer so that you can ensure that students review the work of a person in another group - not their own.
Ensure that students look at the rubric so they have a clear understanding of the assessment criteria.
Project Rubric (extract from https://cgscholar.com/bookstore/web_works/probability?category_id=learning-by-design-modules-k12)
Learning Intention: To give feedback on other students’ works and then revise my own.
Check your Notifications for Feedback Requests: You have received a Feedback Request. Click on this link to take you to the work you have been assigned to review.
Go to Feedback => Reviews => Review Work. Rate the work on each criterion and explain why you gave the work that rating. Make in-text comments at Feedback => Annotations.
Submit your feedback once it is finished at About This Work => Project => Status. You will not be able to submit your review until you have completed the Review and Annotations.
For more information, see Reviewing a Work and Submitting a Review and Annotations.
Revision Phase
The next stage of the writing process is to revise your own work.
Check your Notifications for a Revision Request: You have received a Revision Request. Click on this link to take you to the most recent version of your work. Then go to Feedback => Reviews => Results to see the reviews and Feedback => Annotations to see in-text comments. Once you have incorporated all of the feedback (Reviews/Annotations) from your peers, click “Submit Revision” below the work.
You can also write a self-review, explaining how you have taken on board the feedback you received.
For more information, see The Revision Phase.
Comment: Do you have any questions about Scholar? Make a comment in this update. If you think you have an answer to another student's question, please answer it. Start with @Name.
This Update covers two phases of the writing process in Scholar - Review and Revision. Post it directly into a Community when students are up to this phase of their writing projects. They will also receive Notifications.
Refer to Analytics to monitor how students are progressing with their writing and their reviews
