When I watched this video with my two-year-old daughter I intially thought the video was cheesy and silly. However, my daughter loves it. She dances and sings to the music and asks to watch it almost everyday. The bright colors, dancing, and catchy songs keep her attention while teaching basics such as numbers, letters, seasons, body parts, etc. I would definitely recommend this tape for children six and younger.

You may want to pass on this one...
If you're over 18 or if you're buying it for smaller children (say, under 8.) The graphics are really cheesy--think 1970's disco--and the music sounds like every synthesized excercise class you've ever seen on TV. There's very little "Rock" in this video. However, the "Learn" is there, if you can get past the cheddar. The vocabulary is good...basics from numbers to "pass the carrots" and "please be quiet" is covered. This would be a good introduction or review for middle school or high school students. The video is not really geared for younger children and can become boring. My 3 year old will watch it for a while--especially the number portion...but then she (and I) get bored and attention wanders. The graphics are repetitive and the music can be soporific.

Great for Pre-K thru beginning Adult
Our 4 yr girl and 5 yr son love this video, and so do I. Even our 18 month will watch it. Good visuals, fun music, lively scripting. Starts at a very easy level and builds progressively.

I speak Spanish for business and have enjoyed watching this with my kids. Its been a useful tool for developing their interest in learning another language.

I have this video and my children age 2 and 6 both watch it. I find that it starts out pretty simple with teaching names of body parts, colors and numbers and then gets harder by teaching whole sentences. Everything that is said in English is repeated in Spanish. Ex: If they say, "Let me teach you a trick", they will repeat Déjame enseñarte un truco. I find the latter part of the video helpful only if you already know some Spanish. It is good to have on hand and I find that it keeps the kids' attention with all the dancing and music.
