I got "Moebius Noodles" and "Avoid hard work" for myself and our kids. Both books are focused on playfully teaching kids logical and mathematical thinking and contain several games which introduce functions, algorithms and other programming concepts. My kids were 3 and 5 when we started and really enjoy it. There is a number of tips in both books how to make excercises age appropriate even for toddlers. The main thing to remember, keep it fun and let the kids explore solutions (see recent other discussion on HN)
