I was looking for a series that I used to read as a kid and found out that they were discontinued. I ended up coming across this series and I found them not only beneficial for my kids but also a reminder for myself. I like christianbooks.com!
I was not really expecting much for the price. The small paperback book doesn't have but a few pages in it giving short examples of the subject matter, one example per 2 pages allowing only a few examples per book. For a buck a book, it is okay for using a base communication with your children as a referral guide to identify with daily challenges of the particular topic. I do think it is overpriced for the amount of information, but it can create story-time into learning-time.
