Po v\u010derej\u0161\u00ed celkem \u00fasp\u011b\u0161n\u00e9 hodin\u011b jsem se dnes vydala do \u0161estky zase pln\u00e1 el\u00e1nu. Nerozh\u00e1zelo m\u011b ani poblik\u00e1v\u00e1n\u00ed elekt\u0159iny, kter\u00e9 doprov\u00e1zelo rodinn\u00e9 vst\u00e1v\u00e1n\u00ed i rann\u00ed provozn\u00ed poradu. Po dvou p\u016fldenn\u00edch v\u00fdpadc\u00edch minul\u00fd t\u00fdden n\u00e1s asi v\u00e1\u017en\u011b u\u017e nic nerozh\u00e1z\u00ed. Jak s t\u00edm mrk\u00e1n\u00edm co p\u011bt minut byla spokojena technika, je ale v\u011bc jin\u00e1.<\/p>\n

Do \u0161estky jsem tedy vstoupila s nad\u0161en\u00edm. Zopakovali jsme si v\u010derej\u0161\u00ed pojmy i to, jak pozn\u00e1me, do kter\u00e9 skupiny \u00fahel podle velikosti pat\u0159\u00ed. D\u011bti si cvi\u010dn\u011b a kontroln\u011b zm\u011b\u0159ily a nar\u00fdsovaly n\u011bkolik \u00fahl\u016f a rychl\u00edci dostali do ruky jeden \u00fahel tup\u00fd a jeden ostr\u00fd, aby je zm\u011b\u0159ily a pak se zamyslely nad t\u00edm, jak z nich bez \u00fahlom\u011bru vyrobit \u00fahly polovi\u010dn\u00ed. Sed\u011bli, dumali, s \u00fahlom\u011brem si pohr\u00e1vali. „A co to p\u0159elo\u017eit,“ napadlo Lenku. BEZVA.<\/p>\n

A tady za\u010dal k\u00e1men \u00farazu. Div\u00edte se? J\u00e1 se taky divila. A div\u00edm se po\u0159\u00e1d. N\u011bjak jsem netu\u0161ila, \u017ee p\u0159ehnut\u00ed pap\u00edru na p\u016fl se zachov\u00e1n\u00edm vrcholu m\u016f\u017ee b\u00fdt tak velk\u00fd probl\u00e9m. Prob\u011bhlo n\u011bkolik n\u00e1zorn\u00fdch instrukt\u00e1\u017e\u00ed.<\/p>\n

„Vrchol si dejte sm\u011brem nahoru a celou dobu ho tam nechte. Uka\u017ete si jedno rameno \u00fahlu, druh\u00e9 rameno \u00fahlu. Ta dv\u011b ramena mus\u00edte dostat k sob\u011b, aby se p\u0159ekr\u00fdvala. Vrchol m\u00e1te po\u0159\u00e1d naho\u0159e. “ Mluv\u00edm a sou\u010dasn\u011b ukazuji. Pak proch\u00e1z\u00edm. „Opravdu se ti ta ramena p\u0159ekr\u00fdvaj\u00ed?“ „Kam se tob\u011b pod\u011bl vrchol? Pro\u010dpak si vyr\u00e1b\u00ed\u0161 jin\u00fd?“<\/p>\n

\"matika\"<\/p>\n

Marnost nad marnost. Nakonec jsem stejn\u011b obch\u00e1zela ka\u017ed\u00e9ho zvl\u00e1\u0161\u0165. Div\u00edme, \u017ee si d\u011bti nep\u0159e\u010dtou psan\u00e9 instrukce, ale on je pro n\u011b probl\u00e9m \u0159\u00eddit se i t\u011bmi \u0159e\u010den\u00fdmi a p\u0159edv\u00e1d\u011bn\u00fdmi.<\/p>\n

N\u00e1sledn\u00e9 kontroln\u00ed m\u011b\u0159en\u00ed toho, zda n\u00e1m opravdu vznikl \u00fahel polovi\u010dn\u00ed velikosti, bylo u\u017e celkem rychl\u00e9.<\/p>\n

A pro velk\u00fd \u00fasp\u011bch si zkou\u0161\u00edme tot\u00e9\u017e i s ostr\u00fdm \u00fahlem. A v\u00edte co? Bylo to stejn\u00e9.<\/p>\n

Dva p\u0159ehyby pap\u00edru a dv\u011b m\u011b\u0159en\u00ed = celkem 15 minut pr\u00e1ce. UUUUF.<\/p>\n

Tak\u017ee napl\u00e1novan\u00e1 pr\u00e1ce se pak u\u017e smrskla jen na n\u00e1vod sestrojen\u00ed osy \u00fahlu na pap\u00ed\u0159e. Nav\u00e1z\u00e1n\u00ed na to, \u017ee u\u017e znaj\u00ed konstrukci osy \u00fase\u010dky se nekonalo. Stejn\u011b tak u\u017e jsme osu nevyu\u017eili pro konstrukci \u00fahl\u016f 90, 45 a 135 stup\u0148\u016f.<\/p>\n

A chvilka na tangram? Kdepak by se vzala. Dneska se mnou houpa\u010dka spadla z v\u00fd\u0161ky a p\u011bkn\u011b drncla.<\/p>\n

Alespo\u0148 m\u00e1me na z\u00edtra p\u0159ipravenou evokaci. \ud83d\ude42<\/p>\n

(A ned\u00e1m jim s t\u00edm modelov\u00e1n\u00edm pokoj. Z\u00edtra si zap\u0159ekl\u00e1d\u00e1me pap\u00edr znovu.)<\/p>\n

Jak jste na tom s geometri\u00ed vy a va\u0161i \u017e\u00e1ci?<\/p>\n","protected":false},"excerpt":{"rendered":"
