| Pob tshab pob teeb Txheej txheem nws yog siv rau cov tub ntxhais kawm lub tsev kawm ntawv me kom nkag siab txog kev cuam tshuam ntawm cov ntim, kev sib txheeb ntawm cubic centimeter thiab cubic decimeter. Ua cov yas zoo zoo hauv cov xim dawb thiab pob tshab. Txhua lub teeb suav nrog: - Lub Hauv Paus Kaum Lub Thawv Sau 10x10x10cm 1pc.– Lub Hauv Paus Kaum Lub Rooj Sib Tham 10x10x1cm 9pcs.– Lub Hauv Paus Kaum Lub Nkoj 10x1x1cm 9pcs– Lub Hauv Paus Kaum Chav 1x1x1cm 10 pcs3 |
Geometry: (1) Thaum peb tsuas yog kawm txog qhov luaj li cas thiab qhov loj me ntawm yam khoom, tab sis tsis yog lwm yam khoom (xws li xim, qhov hnyav, tawv tawv, thiab lwm yam), peb hu qhov khoom no geometry, lossis ntim kom luv. Piv txwv li, cov thawv hauv daim duab 1 thiab cov thaiv ntoo hauv daim duab 2, txawm hais tias lawv cov xim, qhov hnyav, tawv thiab cov khoom siv tsis sib txawv, tsuav yog lawv muaj cov duab thiab qhov loj me, peb suav tias lawv yog ob qho sib luag Geometry. Qhov tseeb, txij li cov duab thiab qhov loj ntawm lub thawv thiab cov ntoo thaiv tau zoo ib yam, lawv yog ob lub cub tsis zoo ib yam [2]. (2) Qhov tsawg ntawm qhov chaw uas tau ntim ntawm cov dav hlau thiab cov phiajcim, xws li cuboid, fab, kheej kheej, kheej kheej, thiab lwm yam.
Cov duab thiab qhov loj ntawm cov khoom yog qee zaum hu ua “daim ntawv sib thooj”, thiab lub cev geometric yog qhov khoom tiag tiag uas tsuas yog xam los ntawm qhov pom ntawm daim foos.
