Odin termin iz vashikh nachalnykh dney, kotoryy vse yeshche vyzyvayet zatrudneniya u studentov, - eto termin «tsennost», osobenno v otnoshenii drobey. Yesli by ya sprosil vas: «3/4> 1/2», chto vy skazhete? Vy i pochti vse ostalnyye skazhete «Da». Na samom dele otvet «ne obyazatelno». Problema zdes v tom, chto simvoly drobi na samom dele ne imeyut ZNACHENIYA, poka vy ne uznayete «iz chego». 3/4 dyuyma bolshe 1/2 futa? Konechno, net? Pochemu net? Vy tolko chto skazali mne 3/4> 1/2.

Veroyatno, luchshiy sposob vyuchit formuly - eto delat kartochki po mere znakomstva s novymi formulami. Sdelayte 2 nabora kartochek. Pervyy nabor dolzhen imet nazvaniye formuly s odnoy storony - Ploshchad treugol nika - i polnuyu formulu s drugoy storony - A = 1/2 b h. Vtoroy nabor kartochek dolzhen imet formulu na odnoy storone - A = 1/2 b h - s formulirovkoy formuly na drugoy storone - Ploshchad treugol nika ravna polovine proizvedeniya osnovaniye umnozheno na vysotu treugol nika. Pri rabote s flesh-kartami: poprosite kogo-nibud porabotat s vami, rabotayte tolko okolo 10 minut za raz, no delayte neskolko podkhodov v den, poka vse ne zapomnitsya i ne stanet osmyslennym. Poslednyaya mysl: ne prosto izuchayte populyarnyye formuly - VYUCHITE IKH VSE!

Nedavno ya prochital blog uchitelya matematiki, kotorogo bolshe vsego bespokoit elementarnaya matematika i gramotnost. Mne prishlos posmeyatsya nad primerom, kotoryy on ispolzoval - pochemu my ispolzuyem slovo «zaimstvovat» v vychitanii, yesli ne sobirayemsya vozvrashchat yego? Eto khorosho podnyatyy vopros. V matematike my sklonny ispolzovat terminy iz povsednevnoy rechi, no v matematike eti terminy chasto imeyut ochen raznyye znacheniya. Eto mozhet byt i chasto yavlyayetsya istochnikom putanitsy dlya mnogikh studentov, izuchayushchikh algebru; i, k sozhaleniyu, ucheniki chasto dazhe ne osoznayut, chto oni pereputali znacheniya termina, a uchitel ne ulavlivayet etogo, poka ne stanovitsya slishkom pozdno. Pod «slishkom pozdno» ya podrazumevayu, chto oshibka byla povtorena i prochno ukorenilas v vashem mozgu. Eti oshibki trudno ispravit. Luchshe izbegat etogo, chem pytatsya ispravit.
