Bit eside kwi-mathematics. Sum kancane imigomo

Ubungoti izindlela etemlomo nalabhalwako sibalo incike nokwenziwa izingane imibuzo ababebalelwa izinombolo. On cwaningo izindikimba ngamunye wathi esikoleni samabanga aphansi ekilasini inikezwa inamba ezithile amahora. Njengoba umkhuba ubonisa, akusiyo njalo isikhathi esanele isebenzise amakhono, okuyinto bunikezwa uhlelo.

Eqaphela ukubaluleka udaba, i umfundisi ongumakad 'ebona nakanjani zifakwe isifundo ngasinye umzimba okuhlobene izinombolo ngezinombolo. Ngaphezu kwalokho, kuzokuvumela lezi izinhlobo zemisebenzi, kanye ukulandelana zabo abafundi isethulo.

izidingo zohlelo

Ukuze uzwisise ukuthi yini edingekayo ukuze ukubabela uthisha nabafundi bakhe, owokuqala kufanele wazi ngokucacile izimfuneko ukuthi ifakwa phambili kwi-mathematics sonke isimiso, futhi ezindabeni ezibalelwa ethile.

• Lo mfundi kufanele babe sebakwati iyiphi inombolo (ukuqonda indlela yokukwenza) futhi ukubabiza - imfuneko esiphathelene izinombolo ngomlomo.
• Ngokufunda numeration ebhaliwe, izingane kumele ufunde nje kuphela ukurekhoda inombolo, kodwa ukuqhathanisa kubo. Nokho, zisekelwe ulwazi ukubaluleka lawela we idijithi kunombolo okufakiwe.
• Umqondo "osenyameni", "kancane iyunithi", "zabaluma elithi" izingane zifunde wonkhe ebangeni lesibili. Kusukela ngaleso sikhathi imigomo zifakiwe esebenzayo silulumagama abafundi. Kodwa uthisha babezisebenzisela izifundo izibalo ebangeni lokuqala, ukufunda imiqondo.
• Yazi amagama kwamadijithi ukurekhoda inombolo njengoba kancane isamba imigomo asetshenziswa umkhuba, iyunithi efana kwe-akhawunti, njengoba idazini, ikhulu, inkulungwane, nokuzala ukulandelana iyiphi ingxenye yezinombolo yemvelo - futhi uyimfuneko zohlelo ulwazi abafundi esikoleni sabaqalayo.

Indlela yokusebenzisa umsebenzi

Umgwaqo ohlongozwayo imisebenzi iqembu alandelayo azokusiza uthisha ukwakha ngokugcwele amakhono ukuthi kuyogcina kubangele imiphumela efiselekayo ukuthuthukiswa kwamakhono ikhompyutha kwebafundzi.

Izivivinyo ingasetshenziswa ekilasini ngesikhathi akhawunti temlomo, ukuphindaphinda we indaba ngesikhathi ukufunda entsha. Abakwazi inikelwe njengemsebenti wasekhaya, e-ikilasi umsebenzi. On a Ukuvivinya impahla utitjhere angahlanganisa ahlele iqembu, frontal kanye namafomu ngabanye womsebenzi.

Kuzoya kakhulu ngokuthi arsenal of amasu nezindlela ukuthi ziphethwe uthisha. Kodwa ukusetshenziswa njalo ukulandelana imisebenzi nokuqeqeshwa amakhono - izimo esemqoka ezokwenza ukuthi iholela empumelelweni.

Bakha inombolo-

Lokhu okulandelayo izibonelo umzimba eklanyelwe Ilungile ukuqonda izinombolo imfundo. Bona edingekayo lemali kuzoncika ezingeni abafundi ekilasini.

1. Ukusebenzisa umdwebo, usitshele ukuthi inombolo okuholela. Ifunde (izilinganiso ezingamakhulu amabili, amane kweshumi, 3). Inombolo ikhombisa zeJiyomethri, ezifana onxantathu ezinkulu kanye nezincane, amachashazi.
2. Record nokufunda inombolo. Dweba sawo safaka amagama weJiyomethri. (Thishela ufundeka kanje: "2 amakhulu, amashumi 8, amayunithi 6" Izingane ulalele umsebenzi ke ngokulandelana mboni.).
3. Qhubeka ukurekhoda iphethini. Funda izinombolo kanye ekubadonseleni imodeli. (.. 4 amaseli = 8 amayunithi amaseli 4 0 8 eziyishumi amayunithi = 408; ... 3 iseli 4 iseli amayunithi = ... ... ... amayunithi eziyishumi = ........).

Sibiza bese ubhala inombolo

1. Bonisa yalolu hlobo zihlanganisa imisebenzi ezidinga ukushayela inamba olunikezwa imodeli weJiyomethri.
2. Shayela lenombolo ngokuthayipha kubo ku-canvas: 967, 473, 285, 64, 3985. Yini ziqukethe amayunithi esigabeni ngasinye?

3. Funda umbhalo bese ubhala ngasinye izinombolo ezibalula: ... izimoto eziyisikhombisa zithutha eyodwa ... nanye namakhulu amahlanu nambili futhi ikesi utamatisi. Koze kube nini izimoto ezifana ukuba baphathe ezimbili namakhulu ayisishiyagalombili neshumi nesishiyagalombili ... ezifana amabhokisi?

4. Umlando inombolo kwamadijithi. Amanani obonakaliswe ezincane: 8 amaseli. amayunithi 4. = ...; 8, m = 4 cm ...; 4 amaseli. 9 eziyishumi. = ...; 4 m DM = 9 ...

Siyafunda nokumadanisa iinomboro

1. Funda kuzo lezo aqukethe 41 eziyishumi. 8 PC. 12 eziyishumi. 8 des. 8 PC. 17 des.

2. Funda inombolo bese ukuwathola isithombe ezifanele (ebhodini kukholamu efanayo zilotshiwe izinombolo ezahlukene, futhi enye - in kungekho oda esithile ziboniswa amamodeli we lezi zinombolo, abafundi kufanele usungule ezibhalelwa amabandla.)

3. Qhathanisa inombolo: 416 ... 98; 199 ... 802; 375 ... 474.

4. Qhathanisa value: 35 cm 3 m ... 6 cm; M 7 ... 9 cm 9 cm 3 m

Sisebenzisana namazwe kancane amayunithi

1. Express ezahlukene kancane amayunithi 3 amaseli. 5 eziyishumi. amayunithi 3. = Engamakhulu .... ... amayunithi. = ... dess. ... amayunithi.

2. Gcwalisa ithebula:

3. Yenza inombolo inothi, lapho inani 2 kubonisa osenyameni ibutho lokuqala 92; 502; 299; 263; 623; 872.

4. Qopha inombolo enamadijithi amathathu, lapho inani ilingana amayunithi amathathu namashumi - ayisishiyagalolunye.

Sum kancane imigomo

izibonelo:

1. Funda umbhalo ebhodini: 480; 700 + 70 + 7; 408; 108; 400 + 8; 777; 100 + 8; 400 + 80 Ohlwini lokuqala Hlela izinombolo ezintathu idijithi, bit isamba imigomo kuyakuba kukholamu yesibili. Zixhunywe imicibisholo kwinani nge ukubaluleka kwayo.
2. Funda uNumeri: 515; 84; 307; 781. Miselela kancane isamba imigomo.
3. Bhala phansi inombolo idijithi amahlanu, okuzoba imigomo yamadijithi amathathu.
4. Bhala inombolo-idijithi eziyisithupha equkethe eyodwa kancane eside.

Ukufunda izinombolo ezinkulu

1. Thola futhi ukugqamisa inombolo enamadijithi amathathu-: 362, 7; 17; 107; 1001; 64; 204; 008.
2. Record izinombolo okuyiwona 375 we ekilasini amayunithi lokuqala nelesibili ekilasini amayunithi 79. Yiziphi esiphezulu futhi okungenani kancane eside.
3. I efanayo futhi ihluke nomunye ka pair ngamunye 8, futhi 708; 7 futhi 707; 12 futhi 112?

Sebenzisa iyunithi entsha akhawunti

1. Funda izinombolo kanye ukungitshela bangaki amashumi ngamunye kubo: 571; 358; 508; 115.
2. Bangaki amakhulu ku irekhodi ngamunye inombolo?
3. Phula amaqembu amaningana asekele abalithandayo: 10; 510; 940; 137; 860; 86; 832.

Inani lawela we idijithi

1. Kusukela izibalo 3; 5; 6 Yenza konke kungenzeka enamadijithi amathathu-izinombolo.
2. Funda inombolo 6; 16; 260; 600. inombolo Yikuphi iyaphindwa ngamunye wabo? Lokho akwenza kwathinta ukuthini?
3. Thola letifanako kanye netintfo letehlukile ngokuqhathanisa izinombolo eziphakathi kubo: 520; 526; 506.

Akwazi ukubala izinhlayiya ngokushesha futhi ngendlela efanele

Imisebenzi yalolu hlobo kufanele zihlanganisa ukuqeqeshwa ezidinga ethile izinombolo ukubeka in inyuka noma kwehle. Ungakwazi umeme abantwana ukubuyisela oda okhathazekile of izinombolo, ufaka ulahlekile, ukususa izinombolo ezingeziwe.

Sithola amagugu zenombolo

Ukusebenzisa ababebalelwa ulwazi abafundi baye akukho nobunzima ukuthola amanani wokuboniswa lwemsebenti: 800 - 400; 500 - 1; 204 + 40 Lokhu kuyoba usizo uqhubeke ucela izingane ukuthi babone, ekwenzeni isinyathelo, cela ukubabiza lokhu noma lokhuya eside kancane, bebaqaphelisa isimo amadijithi ofanayo inombolo njalo njalo. D.

Zonke izivivinyo zihlukaniswe amaqembu lula ukusetshenziswa. Ngayinye yalezi kungenzeka kulekelelwa uthisha ebona ngayo. Imisebenzi yalolu hlobo unothile kakhulu Mathematics. Bit imigomo ukukusiza ufunde mayelana nokwakheka kwe noma iziphi izinombolo ezinkulu, okufanele kungene indawo ekhethekile ukukhethwa imisebenzi.

Uma le ndlela ekutadisheni izinombolo kanye izinombolo isakhiwo sabo osenyameni izosetshenziswa othisha ngesikhathi kweminyaka emine esikoleni samabanga aphansi, bese yalokho omuhle ngeke ngempela azoboniswa. Izingane ngeke kalula futhi ngaphandle amaphutha ukwenza izibalo izibalo yanoma yimuphi yinkimbinkimbi.
