Highly Recommended!!
I've used Potato Pals 1 and 2 at Happy English Club Ltd, an EFL school based in Nagoya, Japan for about 5 years now. The Potato Pals books are a wonderful resource to have in class.
The stories can be read as is or shortened according to the level of the students I am working with.
The artwork is very child friendly and holds the attention of even the most restless kids.
There is also a Potato Pals dance that goes with the theme song that my 4, 5 and 6 year old students love to do. I think there is a video of the dance on Patrick's blog. If not ask him to post one and I am sure he will oblige.
Overall the Potato Pals are an excellent resource for the EFL classes I run at my school.
