For the past couple of years. we have been using the mnemonic un avocat to remind students what they need to include when speaking and writing in French. Initially, I had these printed out as posters on A2 for the classrooms. The next step was to make the poster interactive with short explanations behind it so that students could access it at home. You can link to the interactive version here. Click on the initial letter to get more details and the avocado in the bottom left corner to return to the main page. Have a go and let me know what you think!
