Kutamba nemwana zvakasiyana-siyana zvemakemikari geometric, iwe unomubatsira kukudziridza mafungiro ekufungidzira nekufungidzira. Anotanga kunzwisisa kuti chii chakakosha, chakakomberedza, cubic, spherical, uye mabheji uye anogona kuzvifungidzira zviri nyore mumusoro wake. Kunyangwe kuvadzidzi kuchikoro muchidzidzo chemajeriyamu, vadzidzisi vanogara vachiratidza kunyorera kwezvifananidzo zvakasiyana-siyana, izvo zvinoita kuti kuve nekusimudzirwa kwemajetomiyamu maoremomi uye axioms. Uye, zvichida, shoko rakaoma zvikuru uye rakaoma-kuzivisa kune mwana ndiye "parallelepiped". Kuti uzive chiyero ichi uye unzwisise maitiro ayo, tinokurudzira kuti iwe nomwana wako muite parallelepiped pepa nemaoko avo.
Kuita izvi iwe uchada:
- mapepa mapepa (asi kwete makadhibho, kana zvisina kudaro mwana achaita dambudziko rakawanda rematambudziko akawanda), unogona kushandisa pepa kubva pane album;
- pencil;
- mutongi;
- cise;
- glue PVA.
Kuti unzwisise nzira yekuita parallelepiped pepa, unofanirwa kuyeuka maitiro ayo uye kuti chii. Ichi chiyero chine zviso zvitanhatu, chimwe nechimwe chine rectangle. Nokudaro, iyo scan ichabatana ne6 rectangles inonamatira mumhepo imwe chete.
1. Nenzira ipi neipi yekudzivirira, iyo yakaparadzaniswa yakareba, yakareba uye yakakwirira. Iko kubva pakukosha kwavo kuti ukuru hwekugadzira huchabva. Tsanangura zvinoda kuwanda uye nyora pasi.
2. Tinopfuurira kutora mufananidzo weparalllepiped pamakona. Yeuka kuti pepa racho harifaniri kunge rakanyanya kuonda, rinogona kunge rakanyorova kubva kune glue uye rakaputika, saka chimiro hachibudi kunyange, uye kadhibhodhi yakawandisa haigoni kupfugama uye ichaputika.
3. Dhirosa mutsara wakareba, iyo yakareba yakaenzana nehuwandu hwehupamhi nehupamhi, huwandu nehuviri. Zvadaro kubva pamagumo ose emutsara tinoderedza zvisizvo zvakaenzana nekureba kwepallelogram inofungidzirwa. Pakati pavo vanobatanidza mutsara wakafanana nekutanga.
4. Zvino, kubva kumusoro kwekona yekona, tinoronga kukwirira kweparalllelogiramu, uye yakafara. Zvakare zvakare kukwirira, uye zvakare hupamhi. Kubva pamakumbo akawanikwa, tora mitsetse yakasiyana-siyana kune rumwe rutivi, iyo inenge yakaenzana nekureba kweparallelogram. Saka tine zviso zvina zvemufananidzo. Pane zvimwe 2 zvakasara.
5. Pamusoro pemutsara wechipiri uri kurudyi, tinowedzera mamwe maviri kusvika pasi uye pamusoro. Muchiitiko ichi, kubva pachikamu chechipiri kurudyi, chatakaita mudanho rechina, tora chirevo chepamusoro chinokwana nekukwirira kwechimiro. Dzokorora zvakafanana kubva pane chikamu chechipiri. Isu tinobatanidza perpendiculars nechikamu chakaenzana nehupamhi hweparallelogram. Nenzira imwecheteyo, tinovaka rutivi rwezasi kune rumwe rutivi.
6. Kuti uite kuti zvive nyore kubata parallelepiped kubva pamapepa, wedzera mamwe "mapapiro" kumufananidzo, sezvinoratidzwa mumufananidzo. Iwawo hupamhi hunofanira kuva inenge 1.5 masikati uye inofanirwa kuita kuti zvive zvidimbu (45 degrees), kuitira kuti kana paine glued havatarise kunze.
Saka, kuparadzaniswa kweparallipped ye pepa yakagadzirira. Zvakakosha kuti zvose zvakadzama zvekudhirowa zvakaenzana uye zvakanyatsotaridzirwa, zvisinei kuti chimiro hachibati pamwe chete uye chichave chikafu.
7. Gadzira chidimbu chekushanda nekuchikomberedza pamwe chete nemitsetse yose kuitira kuti mativi edu abate, uye rectangles kumusoro uye pasi ave "pasi" uye "chifukidzo" chemufananidzo.
8. Gadzirai mamwe "mapapiro" eine glue uye muunganidze parallelepiped nokuazadza mukati. Ngatimirirei kusvikira glue raoma.
Kana iwe wakanyatsoziva kugadzirwa kwechimiro ichi, unogona kuenderera mberi kuti uunganidze parallelepiped yakagadzirwa papepa, iyo mitsetse yayo yakanyanyisa-madhayamondi.
- Nokufananidzira kwechimiro chekutanga, tora mufananidzo, sezvinoratidzwa mumufananidzo. Sezvaunogona kuona, zviso zvose zvepalidelepiped zvinowanikwa zvakafanana uye mativi ose emadhamondi akaenzana.
- Wedzera kune mufananidzo maapiro anowedzera gluing.
- Nyatsotora chimiro chacho.
Parallelepiped - chimiro chemagetsi ejometri, kunyatsoziva kuti iwe unogona kuenda kune vamwe - kugadzira piramidi yemakadhibhodhi kana pepa, somuenzaniso, icosahedron .
