Masamu a pa tebulo la kukhitchini

Pambuyo pa masabata angapo akusewera masewera ochokera ku Kitchen Table Math: Buku 1, mwana wanga wamkazi wazaka zinayi ankadzuka m'mawa uliwonse akufunsa kuti, "Kodi tingasewere masamu patebulo la chakudya cham'mawa?"

Zinandithandiza

Kwa nthawi yayitali yomwe ndikukumbukira, abambo anga akhala akusangalatsa masamu. Sindinkadziwa kuti masewera omwe tinkasewera poyendetsa galimoto kupita kusukulu kapena kukhala patebulo la kukhitchini ankandiphunzitsa luso lofunika la masamu lomwe linandipangitsa kukhala pamwamba pa kalasi yanga kuyambira ku pulayimale mpaka kusekondale. Kuphunzitsa kwa abambo anga ndiko kunandithandiza kukhala woyamba mu California Math League m'boma lonse mu giredi 6, kupeza zigoli zabwino kwambiri pa mayeso anga a AP Calculus BC mu giredi 10, komanso zigoli zabwino kwambiri pa masamu anga a SAT mu giredi 11. Tsopano, monga wophunzira wa sekondale ku Stanford University, ndikuyamikira kuti adakhala nthawi yayitali akuchita masamu ndi ine, chifukwa anandithandiza kufika pomwe ndili lero.

Monga munthu wokonda manambala moyo wake wonse komanso mphunzitsi wa masamu kwa zaka 35, ndimapeza buku la Chris Wright Masamu a pa tebulo la kukhitchini (buku 1) kuti likhale lothandiza kwambiri pothandiza ana aang'ono kuphunzira mfundo zamanambala ndikusangalala ndi masamu.

Bukuli lakonzedwa bwino, kuyambira ndi kuyamba kuwerengera ndikupitiliza ndi ntchito zoyambira za masamu mpaka kufika pa geometry ndi kuthekera. Malingaliro onse afotokozedwa momveka bwino ndipo amapezeka mosavuta kwa akuluakulu ndi ana. Chimodzi mwa magawo omwe ndimakonda kwambiri m'bukuli ndi kuchuluka kwa zochitika zosangalatsa komanso zosangalatsa. Ndili mwana, banja langa linkadya "usiku wamasewera" pa chakudya chamadzulo madzulo amodzi pa sabata. Nthawi yosankha inali nthawi yanga kapena ya abambo anga, nthawi zonse tinkasankha masewera a masamu. Ndikanakonda kwambiri kukhala ndi malingaliro a Chris oti ndigwiritse ntchito panthawiyo kapena pamene ana anga anali kukula. Ndagulira makope a bukuli kwa zidzukulu zanga zingapo, mdzukulu wanga wamwamuna komanso mdzukulu wanga wamkazi komanso mwana wamkazi wa mnzanga wachinyamata.

Ndikupangira kwambiri masamu a pa tebulo la kukhitchini ngati njira yothandizira ana kukonda kugwira ntchito ndi manambala ndikuzindikira kuti masamu ndi gawo losangalatsa komanso lachilengedwe padziko lapansi.
