As a high school teacher in a school district with a very large Spanish population, I've been meaning to refresh my Spanish for a while.
But I simply did not have the time and patience for a general purpose Spanish course like Pimsleur.
This book covers the most important topics such as classroom discipline, speaking to parents, helping students with their homework and general basic friendly interactions.
The learning is interactive and intuitive. No heavy focus on grammatical concepts, just practical Spanish that I can use.
Would recommend this.
