Summary[edit]

Description
Italiano: La foto rappresenta uno dei materiali montessoriani più noti: si tratta di una scatola di legno apribile in cui sono contenuti parallelepipedi di varie dimensioni, ognuno dei quali rappresenta un membro algebrico del prodotto notevole chiamato "cubo del trinomio". I bambini che seguono il metodo Montessori usano questo materiale dai cinque anni in su e quando poi, alle scuole medie, studieranno i prodotti notevoli in algebra lo riprendono comprendendone anche il significato algebrico.
