I found this book at a discount store and got it because I couldn't resist a bargain.  However, these are hands-down the best devotions for teachers I have ever read.  The book is biblically-based and provides short passages on various qualities that effective teachers need to possess (patience, perseverance, kindness, etc.).  Correlating scripture is given along with a checklist of things to do to help instill the trait in yourself and improve your practice.  Normally I don't like lists like that but these are original, creative, and actually have a positive impact on my teaching.  I really look forward to reading these and keep the book at work so that I can go over a passage when I need encouragement or am struggling with something.

Tips for helping students memorize scripture

God's World News: online and print versions of current events for kids written from a Christian perspective- an incredibly informative and child-friendly site.

Consider having your class sponsor a child through Compassion International or World Vision.  It's about $30 a month, so each child could contribute $1 a month and you pay the balance, or you could handle the financial aspect and have the class  be in charge of contacting and supporting the child.  I just 'adopted' a little girl in Tanzania that I will be writing to and sending pictures to reguarly.  I went to Compassion International's website and was able to see a picture and read a bio about each child and pray over which specific one God wanted me to choose.  Compassion makes sure each child writes back at least 3 times per year.  This is a great authentic purpose for writing and an opportunity for students to research another part of the world.  There are so many curriculum tie-ins: you could easily turn this into a geography lesson (you can chose the region you'd like your child to come from), track and graph the weather in your child's country and compare it to your own for math and science instruction, and so on.  Most importantly, the experience will instill in students a sense of empathy, generousity, and gratitude.   Receiving letters back is incredibly rewarding.  I would love to be able to share this experience with my students but would be in serious danger of losing my job if I did so- if you have the opportunity, pray about it and see if the Lord might lead you to sponsor a child with your class this year.  Please let me know if you do and pass on your incredible stories about how God is using your class to minister to another part of the world!!
