I really liked this link because it would go along great with the unit that I'm doing for class. The only thing that I don't really like about it is that it's a worksheet so I would rather have the students create their own trees instead of using the worksheet.
This is a website that allows you to create worksheets for students. There are a variety of styles (word finds, learn-to-read books, puzzles, etc). It is primarily designed for younger students (K to 8 or so), but can be used for any grade. I use it to create sponge activities that reinforce the content of the lesson plan.
This is a great site for educators! There's a whole section on puzzle making, lesson plans, unit ideas, themes, worksheets, and more! Definitely check it out!
Similar to edhelper resource that was recently posted (Sorry David) for a second time. Includes a variety of worksheet generators, lesson plans, rubrics, assessments, etc. Certainly worth bookmarking for future reference!
