A few months ago, something came up that made me show the Mini simple addition using my fingers. He was so mesmerized by 'plus' that he requested for a 'plus activity!'.
But next day, as soon as he came back from school, he asked if I had set up the 'plus activity'! π Well then, follow the child they say! So, I set this maths busy box for him. I wanted to keep it as simple and straight forward as possible.
