Learning designer (www.ucl.ac.uk) is the start point to plan the study unit. After working the contents of the lesson, students read (always in English) the activities plan, before perfoming the interactive activities using educational Apps.
In this case, they created an audio book about biotipes with Story Jumper, with the students own voice, explaining the contents of the topic.
Some games with Kahhot! served to review and consolidate everything they had learned.
And finally, the fantastic App Plickers evaluates how much the students have learned.
