Each week I send out a spelling list for the students to study at home. This document has each week's list. Each page has 6 copies of the same list. I just cut them apart and put them in a basket in the classroom. Before I send it out, I put the date that the students will be given a spelling test.
I use the words from the Wonders Phonics/Spelling workbook.
Additionally, I use this list in the classroom. Students use it to help each other study. I have older students, parents, and paras who come in the classroom and use it to help teach the students their weekly spelling.
