In school we have also been using the App 'Smiling Mind' (https://www.smilingmind.com.au/smiling-mind-app) as a mindfulness tool. This is a great app for helping children to think more about the world around them and their own emotions. They have a Year 2 Curriculum that you can pick and choose ideas from if you wish to do so. The lesson 'The Bubble Journey' is a particular favourite.
Go Noodle also have a section on mindfulness and thinking tools that are worth investigating. You need to sign up with a family account to access the videos and games.
