Sorting cum threading

I gave a tub of buttons of different shapes and colours to Balqis.and her first task was to sort them according to different shapes. She successfully did just that. Her second task was to sort it according to the different colours. She was a bit confused probably because some of the buttons come in different shades of a particular colour. Eg. Light, dark and also translucent sort of red. I think its time I introduce her to family of colours.
She did some threading with the buttons too and I am very happy that her fine motor skills is getting much better now. She could thread through the small holes of the buttons.
