and this made me think about how this idea could be adapted to create a craft activity to help children learn about emotions.
First of all you need a collection of pebbles or stones, then things to decorate them with - as you can see this one uses googly eyes, wool and a bit of pipecleaner but you can use whatever you want - if you wanted you could just use paint or a marker pen to draw on the pebble.
Then make a collection of different faces; happy, sad, scared, surprised, angry - talk about the emotion, what makes people feel that way, or act out scenarios with your pebble people. You could also make an identification game by putting the pebbles in a bag and picking one out - or a matching game matching the pebble to a picture of someone showing an emotion or a scenario.
