Hello Mary.
>About how to grade.
I suppose to give instructions like
1. "Is the triangle, circle and rectangle are drawn by their coordinates?" Yes/no.
2. "Are they reflected relative to the line?" Yes/no
and so on.
>How each student knows what to submit?
Here is the main problem. If I give a task: coordinates of a circle (1,1), of a rectangle (2,3), of a triangle (5,7). And a line goes from the origin by the angle of 30 degrees.
I need to give another student the same task with some changes: coordinates of a circle (5,7), of a rectangle (1,1), of a triangle (2,3). And a line goes from the origin by the angle of 60 degrees.
And I don't know how to give it in a such way. Further, in order to check other work a student B needs to know the task of the student A.
May be I can attach a list with 150 tasks. How I can allocate the task №138 to the student A, and the task №123 to the student B? And how the student B knows that the student A has the task №138?
The tasks are not individualized for the students. Only some conditions are. But it doesn't change, nor the main task, nor the instructions for grading.
I think that this assignment in such way will be very useful for students to see the symmetry. One picture for all won't give such effect.
>how they are going to draw the shapes
They can draw it on a sheet of paper and take a photo.
