Have you written your own loop? Have you tested it with your students and are you convinced that it works? Would you like it to be included into the free downloadable document so that other teachers can use it? Then please write to email@example.com.
We are planning to update the document twice a year, and the deadline for submitting your own original loop will always be March 31 and August 31. Please understand that we will test all submitted loops and we may decide not to include some of them into the document if we have difficulties implementing them in practice. Thank you!
