Concealing the chessboard he has drawn on his desk, Mike Krawczynski pretends to compute a problem on a box. Expansion Continues for Math Curriculum With New Materials Anyone tor chess? A special new unit in some math classes brought students to direct confrontation over chess boards. The unit helped them develop their pow- ers ot reasoning and visualization ot ge- ometrical patterns. When not holding chess tournaments, the students were taught by customary methods from various new textbooks in the math department. V Another new addition was a typewrit- er with a math keyboard. This machine allowed teachers to type entire tests and worksheets without having to put in mathematical symbols by hand. As his students follow along, Mr. Ryding outlines a proof ot the properties ot a parallelogram. Hoping that they have outwitted the book, Mr. Sadlowsky's probability class anxiously await his studied decision on an answer.
