Rated for 3+ but my 2 and 3 yr. olds both play with this. While the kids like playing with this, I like that it can grow with them. It has basic tools for younger children: rolling pin, presser with three tips, pizza cutter, safety scissors, play-doh knife. But it also has tools/items for older ones: bead making, art molds for pictures and "sand".The only con is the mat. It's cheap plastic. Sounded great on the box in the store, but ends up crinkled underneath them and not protecting the floor. Stick with using and old sheet or vinyl table cloth from the $1 store.

Ex Output:
Positive

Ex Input:
The title of this video mentions Argentine Tango. Unfortunately, what is being taught on this tape is not authentic Argentine Tango. Not even close. It's ballroom tango. There is a huge difference: in music, style, steps, posture, etc... Don't be fooled by ballroom instructors trying to teach Argentine Tango. The only authentic instruction available on the market comes from authentic Argentine instructors from Buenos Aires.

The plot of Clan or the Cave Bear is ok, but I found myself skipping alot as the narrator goes on and on and on. For example, every time the protagonist goes herb gathering with her mentor, 2-3 pages are dedicated to describing the herbs and techniques. A short description would've added some depth to the story, but I really wasn't reading the book to get a lecture on neanderthal medicine.The characters are the saving grace of this story, adding entertainment and almost overcoming the sorry narrative. Almost, overall this book is very boring.One gets the feeling that Auel is trying to make a statement about feminism or male-female relationships, but whatever point the author is trying to make is not clear.I think my money would've been better spent on something else.
