Where is my name tag gone?

We are moving on slowly but surely  in our literacy program and this week, as part of our effort to teach the children to recognise their own names, we removed the pictures attached to their name tags. Each morning the children are to put their name tag up on the board as they arrive in class. Some of them were puzzled yesterday when they realised that their tags were different. Most of them picked the right one straight away while another few were still struggling a little bit but I think we are on the right track. 

This is what their new name tag look like ....

And this is what the younger kids's tags still look like.... See the progression?
