The document provided contains a "STEAM Task-2" for Grade 11 students focusing on matrices, particularly in the context of cryptography. The task is to decode a message using the inverse of a coding matrix, then submit the solution. The rubric outlines how the task will be assessed based on presentation, mathematical communication, personal engagement, reflection, and use of mathematics.

Here’s a breakdown of the key points:

- **Concept**: Cryptography using matrices.
- **Task**: Decode a message using the inverse of a matrix.
- **Rubric**:
  1. **Presentation (2 points)**: Logical organization, accurate calculations, and use of visual aids like matrices.
  2. **Mathematical Communication (2 points)**: Correct use of notation, clear steps, and diagrams.
  3. **Personal Engagement (1 point)**: Creative approaches or alternative methods.
  4. **Reflection (2 points)**: Connecting decoding with real-world applications.
  5. **Use of Mathematics (3 points)**: Correct matrix inversions and decoding accuracy.

Would you like help with decoding the message, or do you have any other questions?

Here are 5 follow-up questions to expand:
1. What are the steps to find the inverse of a matrix?
2. How is matrix multiplication used in decoding cryptographic messages?
3. What are some real-world applications of matrices in cryptography?
4. Can coding matrices be applied to other forms of encryption?
5. How does the efficiency of decoding depend on the matrix's properties?

**Tip**: Always check if the determinant of the matrix is non-zero before attempting to find its inverse!
