A bit late but are you still looking for a lesson plan for Valentine's day?

Here´s a complete lesson plan from Chrysa Papalazarou for intermediate+, teens+ students on the theme of friendship. What I like about it is that it's designed to get students thinking critically. Chrysa achieves this by including art forms in her class content and applying the VisibleThinking approach to them.

You could use Kath Bilsborough's lesson plan at any time of year with its aim of loosening students up for writing creatively but getting them composing corny love poems. It's for teens+, A2+ students. That's also true of  Cristina Cabal's fun lesson plan which uses a speed dating technique to get students talking.

Finally, here's a short and sweet activity from Eva Büyüksimkeşyan for primary +, A1 students which gets them making heart-shaped cut outs for Valentine's day.
