Cool/Warm art project - I made these with my grade 4/5 students last year. We did not use a photocopy but the rulers width or compass. The nicest and most difficult ones were the students who made lines that intercepted or more than one circle pattern on a page. They looked Fab when done!
I have far too many classes to do this with and my kids wouldnt appreciate it from a student teacher, at least not in class time. But, for those of you with the same class throughout the year and with younger kids, this is a great idea to show them that you appreciate each and every one of them.
