I didn't like this for preschool-1st grade level. I also don't like the writing part because I'm teaching cursive first and this is all in print. I prefer for the vocab to be introduced with the masculine el or feminine la so that they get the idea that there are masculine and feminine words and have that in their head right away. It was not taught that way in this book. It was just "camisa," "perro," etc.
I've decided to take a different approach. There are a lot of things you can find for free for teaching kids Spanish. Keep that in mind. I didn't find any workbooks that I liked for kid Spanish.
I purchased this for the following school year for my child. I looked it over. I think it just might work for us. I think there should be a pronunciation CD to accompany this for those who have not taken Spanish to help with teaching their children. We'll see how this works for us when we start up again at the beginning of Aug 2013.
