Puzzles
Yet those who journey in the garden land of true knowledge,
since they see the end in the beginning,
behold peace in war and conciliation in enmity.
~ Bahá'u'lláh
Puzzles may at first glance seem like just a toy that demands patience, but in fact it is also a means of learning concepts, even mathematical ones.
To solve a complex problem, for example of 500 or 1000 parts, in which you know how to check if the result is adequate or not, you need the same principles and concepts when solving a puzzle: start with the frame of the challenge, divide the pieces into a coherence (colour, type, etc.), first perform the easy, and then the most difficult, how over time, nuances of colours that once seemed invisible, become blatantly visible, and so on. And in the process, with each well positioned piece, a satisfaction that is completed in the last missing, an interesting – and also ephemeral – pleasure.
It is also an honour to perform these abstract mathematical concepts, in a fun way, and as a project in which the whole family participates.
