I use these short sentence copying practice half-sheets in my intervention group. We usually do one practice section each week to work on copying skills. A lot of students have difficulty copying items from the board to their own notes, and so I use this as an intervention for that skill.
This can also be used to work on writing (using correct placement, spacing and letter formation). I have also used these as sentence dictation practice and blanked out the sentence at the top and orally given it to my students so they can practice writing skills.
There are so many uses for this activity!
