I am not sure who invented these but my kiddos love these hidden word pages. We've done a few and they get so excited when they find the words.
I created an Earth Day hidden word page. I made two versions. Some kids need to know which words they're looking for and some are able to read them and write them without assistance.

I'll be doing some other plant lessons and things for Earth Day (I'll probably share on Friday if I link up for Five for Friday). I also have a rep from the county soil and water conservation coming in 2 weeks to do a lesson on worms and composting! I'm excited. :D
