Interactive Textbooks
I am a former Head of Languages who now works part time teaching French and German. This allows me to write and publish high quality and sensibly priced teaching resources. My best selling resource on the TES is my primary French course, easyMFL, which is a complete Y3-Y6 French course with lesson plans, presentations and assessments. Unlike nearly every other publisher, I don't go in for expensive annual site licences - just buy once and get free updates as they become available.
