There is a little series of clicker training activities posted on YouTube. They can be reached by putting HorseGym with Boots into the YouTube search engine, then clicking on the ‘playlist’ of the same name.
Each clip has an accompanying set of notes with lots of planning and thin-slicing ideas. I am happy to send the notes as a PDF attachment to an email. They are free on request. Just email me at: firstname.lastname@example.org
Or below is the first of the series.
