There are several ways you can use these sheets
Whole Class: Display in room and children can add to it when working.
Small Groups: Children share a couple of sheets as a group and all add words to them.
Individually: Children have their own sheet and might work on one or two words at a time.
The last sheet is blank so you can write in any other words. I have used high frequency sight words. I use magazines, catalogues and newspapers but these could be substituted for other written materials.
