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.
