Μαθηματικά και μοτίβα και γεωμετρία και σχέδιο και τέχνη. Με μπόλικες δραστηριότητες. Ενδιαφέρον για παιδιά δημοτικού και για όσους και όσες θέλουν να καλλιεργήσουν στα παιδιά τους ή στους μαθητές τους αγάπη ή συμπάθεια για τα μαθηματικά.
"La matematica è piena di schemi, e gli schemi possono essere belli, curiosi e affascinanti." Non potrei essere più che d'accordo con questa affermazione. In questo quaderno di attività, si affrontano sfide di disegno tecnico ispirate alla geometria; si scoprono i frattali, ripetizioni della stessa immagine sempre più piccola; si conta con il triangolo di Tartaglia e si risolvono puzzle inventati migliaia di anni fa come lo Stomachion; si unisce lo studio dei colori alla creazione di pattern o all'applicazione delle regole della prospettiva, creando disegni in 3D. Ancora, c'è spazio pure per il problema di colorazione di una mappa con quattro colori e per il Teorema di Eulero sui cicli euleriani. Le spiegazioni sono ridotte ai minimi termini per favorire gli esercizi pratici, trasmettendo però astrazione e schematizzazione. È quindi un libro da laboratorio che propone momenti di gioco e svago arricchiti con tante nozioni di matematica implicite. Carino!
Absolutely phenomenal. Apparently, this is what my heart and mind have been after since childhood. I used to draw lots of these little things throughout my childhood - and, as an adult, I've always felt a strong kinship and attraction to the Renaissance artistic scientist/engineers like Brunelleschi. I've always been amused and tickled and romanced by things like the golden ratio. Well! Apparently what I've been after is math art!!!
This is ostensibly geared towards kids - and I wish I had had this as a kid - but I found this just as amusing and enriching and enchanting as an adult. I don't know why SOME types of games and puzzles are considered "intellectual" or virtuous - the NYT Crossword, for example, or Wordle - while others, like figuring out an Euler circuit are just nowhere to be seen?
I will dive more into this rich and promising vein! Huzzah for math art!
I found this at the Math Museum in NYC this past summer. Not only have I read it, I have my students doing it! I've allowed students who are "pushing the envelope" in my math classes to dive in and have a go. It's fun when playing with geometry can lead to a better understanding of math concepts. This book is kind of like a whole bunch of "math labs" the way I would set up "science labs."
A drawing and colouring book which shows how to make fabulous patterns using the power of maths. The author's enthusiasm seeps through on every page. Topics include circles, parabolics, triangles, fractals, stomachions, spirals, 3D shapes and lots of other cool stuff.
Highly recommend for any child who likes drawing, ages 6+ (you need to be able to read a bit, and have good fine motor skills).
