As an educator I am a big believer in sharing, collaborating and improving. After all we are supposed to be life long learners. In my experience, many teachers are often reluctant to share their materials, for various reasons.
If you are an authorized IB world School you will already have your login details for the Online Curriculum Centre or OCC where you can find excellent examples of MYP Unit Planners for all subjects in the individual subject pages.
However, I have also included several examples of past and present MYP unit planners here and MYP scope and sequence documents here that we have developed here at GJIS. Feel free to borrow, modify or use them if you wish. They are not perfect, they are just examples that we have been using, so please, if you do like them, or perhaps you do not like them, let me know!
