Ok, please forgive me for lumping these together, but its easier for me to just dump them all up in one place. A while back I made this Sentence Search Worksheet on a whim for my students. It went down so well I was ... ahem ... tasked with making a tonne more on a desk-warming day.
Here's the full set, including answer key. I'll be honest, I haven't actually printed and double-checked the validity of the last couple, so best you quickly do that first. I sometimes do muddle a pair of letters up in the final tidy up. I typically draw some hints in the gaps before photocopying (often including a hint to check Page XX of your textbook). Its easier for me to doodle with a pen than find appropriate clipart, sorry. Quality and difficulty may vary as a couple of these units really didn't lend themselves to the concept, hey.
