Question: how to design a 10 week lesson plan to teach english to foreign students? 

Answer: I need more information.\nWho are your students?  That is, what level of English do they have now? (none, some, quite good but need help with vocabulary and accents?)\nFor what purpose are you teaching?  To pass an exam?  For daily life (survival skills), for work vocabulary?\nWhat age are your students?  Children, adolescents and adults all learn differently and have different preferences in teachers.  Children and adolescents like to have 'steath' learning--that is, they do not perceive what they are doing as work.  Young adults and adults are more straight forward and generally prefer some homework for example.\nOnce you know the needs of your learners, you can easily plan a course of 10 weeks that suits their needs.
