A poster to remind each child that he/she is unique & special. This can be displayed in the learning environment so that children always realize that they are unique and special in their own way. You could also encourage your learners to express what their superpower is using the hashtag #MySuperpowerIs & stick them around the poster. They can keep adding their to list of superpowers as time progresses. It could be as simple as something like "#MySuperpowerIs Kindness!"
