Math Materials
During Class Preparation
On the Classes-upcoming page of the teacher app, click [Materials] to enter the pre-class preparation interface.
The [Lesson Content] on the left will display the lesson content，including knowledge points of the current lesson and their corresponding courseware. If students have uploaded materials, they will also be shown here synchronously.
To add additional materials, click [Select Materials], where you can choose from 4 sources: the [Material Library], [Local Files], [Problem Set], or [Most Recent Class].
How to add materials:
Option 1: Adding materials from the Material Library
​
Click [Material Library] to enter the library, which supports searching by [Grade] or [Topic]:
Search by grade: Cosmo’s courseware covers grades K-12. Click a grade on the left, and the trial courses and a list of all modules for that grade will be displayed on the right.
​
For example, after selecting 3rd grade, click [Trial] to view all trial course materials for that grade (marked with "trial" in the upper right corner).
You can also click a module name to display long-term courseware modules.
Each material is presented as a card, containing its name, difficulty level, associated topic, and module. Among materials displayed under a module, those with a [Trial] label in the upper right corner are applicable to both long-term and trial courses. Hover your mouse over a card to view the included knowledge points and thumbnails.
Click on the card to view the full courseware.
To use materials in your classes, check the box in the upper left corner of the card and click [Confirm]—the material and its corresponding knowledge points will be automatically added to the [Material]s list. If you add a lesson by mistake, simply click the small trash can icon to delete it.
Searching by topic: The operation logic to search by topic is similar to searching by grade. After selecting a topic, click the module name.
Material cards will show the name, difficulty level, grade, and associated module. The selection method is the same as before. Additionally, you can filter materials by selecting the "difficulty level" if needed.
Option 2: Uploading local materials: After choosing "Select Materials" on the content screen for your lesson, click [Local File], select a local file, and upload it.
​​
Option 3: Adding questions from the question bank: Cosmo’s question bank covers K-12 grades. When selecting materials, click [Problem Set] to enter the question bank.
Locate questions by selecting grade, module, and knowledge point. If needed, you can also filter by "type" and "difficulty level". After checking the required questions, click [Edit Name and Order], enter the problem set name, and click [Complete]—the selected questions will appear in the course content list as a problem set.
Option 4: Reusing materials from the previous class: To re-use materials from your previous lesson, click [Most Recent Class] from the lesson content screen. The courseware from the last lesson will be added to the current lesson.
Regardless of the source of the material, after entering the classroom, click [Content] - [Select Material] on the left. All pre-class prepared materials will be displayed here. Click to use them directly.
During Class:​​
During a class, click [Library], [Recent Class], or [Local] to add materials in real time.
To add questions, click [Question Bank] - [Insert Questions] on the left, select the questions, and confirm—they will be directly displayed in the classroom.
Accessing Material for Trial Course
The logic for accessing material in trial courses is basically the same as in long-term courses, with the following key differences:
In the pre-class preparation stage, [Materials] by default includes trial course material, a teacher introduction page, a course summary outline, and the students' assessment report.
To add material before class, click [Upload Materials] to retrieve material from the library or upload local files, or click [Create Problem Set] to select questions from the question bank and create a customized problem set
​
The specific operations for adding materials in the classroom are identical to the four options for long-term courses, so they will not be repeated here.
