Green Machine – Glen Small [1977-1980] West Coast Architect Glen Small, an early proponent of environmentally aware architecture, has documented a large range of projects at his website including his well-known proposals Green Machine, Biomorphic Biosphere and Downtown Troposphere. Forget about clinical isometric models, here much of the documentation consist of loose organic sketches of […]

“La Matematica come un romanzo”, in edicola con il Corriere della Sera è un viaggio affascinante alla scoperta dei problemi della matematica e degli uomini che li hanno affrontati.Le equazioni impossibili, le simmetrie nascoste, i teoremi che nel corso dei secoli hanno intrecciato storia, scienza e filosofia, raccontati attraverso le vite eccezionali di matematici incompresi o tormentati, isolati dal mondo o coinvolti nei grandi eventi del loro tempo. Questa settimana in edicola la

In the elementary school and high school mathematics, we are usually treating some statements as facts (or axioms). In reality, many of these statements are actually theorems. This means that if you want to go deeper, it is good to read the proofs of these theorems. Note that all theorems in mathematics, even the most obvious, have their mathematical […]Continue reading...

I like to use card sorts in my math classroom. I've been working on various sets. One popular set I created is for identifying the difference between linear and nonlinear functions. The card sort has 20 cards - 12 equations and 8 tables. Get the link below to the set of cards!When I use card sorts, I don't always tell students the categories I'm looking for. I might tell them how many categories I want them to create. Keeping the categories open allows for a rich discussion about what
