A lesson plan is a guide line that a teacher use to guide them on a certain lesson.As a Foundation phase teacher there are aspects that you need to highly consider in your  lesson plan, firstly you must be able to accommodate all learners that requires you to know more about your students, and what you have to know is about their back ground as you wouldn't want to clash with anyone's capabilities it can be interests or religious it must be an equal lesson for everyone. Research more on the topic so that you present a good  lesson to students and a well presentation. Set the outcomes of the lesson like what should the learners know to after the lesson. The kinds of activities that will be done by both the teachers  and students.Materials that will be used to complete the lessons.how to introduce and do about the activities of the lesson. 
My opinion on utilizing art integration in Foundation Phase it can be to hit to birds with one stone where by  you will be teaching two lesson  lessons in one, it can link the subjects that are taught  in Foundation Phase. It interrelated, again it helps to keep the mind of a student more active and develops and enrich the mind of the student.
My perspective with regards to planning a lesson and the inclusion music throughout teaching and learning in Foundation Phase has changed as I have learned  more about  how to plan a  music activity, what  the concepts that has to be followed to actually do a music activity. I now understand why is music  a Life Skills topic have learned the bvenefits of music to children ,how does it  impact the students.
