Let’s sing and learn the ‘solfa’ actions straight away. The new action (like two fists) can be two ‘buns’. Also, I have turned “re” into a cross shape to fit the words. 

Try and read the solfa notation on the side of the screen, whilst doing the actions.
Remember, only adults need learn to read solfa notation at this stage. Children should be learning by imitation. 
They can imitate the solfa actions. The only 'reading' they do is copying your hands!
