Crying woman (1937) by Pablo Picasso. Qué profunda tristeza siento al contemplarlo! !! There's a movement of cubism in this piece this is because of the use geometry on this works in which was build up with the use of shapes to create this view. Also the use of colour made this piece look lively.
I will use this idea for number facts... each matchbox holding together facts of a specific number(answer) discovered in classroom by the learners ... and writing it on arty backgrounds like these. Thanks!!!
