Indlela yokufundisa ukuxazulula izibonelo ezingaphansi kuka-10?
Kuyinto elula futhi esheshayo ukuchaza ingane ukuthi izibonelo zixazululwa kanjani eminyakeni eyishumi yokuqala. Izimo ezibophezelekile zalokhu yi- akhawunti yomlomo oqaphelayo emuva nangemuva, ulwazi lwezinombolo zangaphambilini nezinombolo ezilandelayo, kanye nokubunjwa kwalo : isibonelo, 5 ngu-1 no-4 noma u-2 no-3.
Ekuqaleni, ukubala izinti ingane ezoyiqonda ngayo ukungeza noma ukukhipha izinombolo kuhle. Kuyinto engathandeki ukusebenzisa iminwe noma umbusi ngokubala - ngakho ingane ayifundi ukucabanga. Lona umbono wabaningi othisha, nakuba empeleni kuvela ukuthi lesi sigaba sibalulekile nje kwabanye. Umuntu uyidlula ngokushesha, kepha omunye uhlala. Uma ingane iqhubeka, kungcono umphumela.
Isibonelo:
Kuzingane, isibonelo esihle kakhulu sokufunda ukushaya amaphuzu. Ukusebenzisa, kulula ukuchaza: 4-4 = 0 noma 5 = 5.
Izibonelo zingabonwa - ukudweba inombolo ethile yama-apula, amaswidi kanye nokunye, ukukhipha noma ukuwengeza.
Indlela yokufundisa ingane ukuxazulula izibonelo ezingafika ku-20?
Uma i-akhawunti engakapheli kweshumi isivele ikwazi kahle, sekuyisikhathi sokuya phambili - funda ukwengeza nokukhipha izinombolo zesibili eziyishumi. Eqinisweni, lokhu kulula kakhulu uma ingane ikwazi "ukubunjwa" kwenombolo futhi inombono wokuthi yini enkulu nakakhulu.
Manje, izibonelo eziyisibonelo zibalulekile njengokuthuthukiswa kweziyishumi eziphezulu.
Isibonelo 1
Cabangela isibonelo sokwengezwa kuka-8 + 5. Yilapho ulwazi lwenombolo ludingeka khona, ngoba u-5 ngu-2 no-3. Nge-8 sengeza u-2, sithola inombolo engu-10, sengeze ku-3 esele, asisekho inkinga.
Isibonelo sesi-2
Ukuze ufundise ukususa, udinga ukuhlukanisa izinombolo zibe izingxenye. Ukuze ususe kusuka ezinhlanu eziyishumi nesishiyagalombili, kufanele uhlukanise inombolo yokuqala ibe isibalo sezinombolo ezingu-10 no-5. Emva kwalokho, hlukanisa ukususa ngo-5 no-3. Manje okwenzekayo okuthakazelisayo kakhulu - kusukela kudijithi yokuqala yokuthatha (10) sisusa idijithi yokugcina kusukela kwesibili kwemigomo yenombolo yesishiyagalombili. Sithola lezo eziyisikhombisa.
Indlela yokufundisa ingane ukuxazulula izibonelo ezingafika ku-100?
Izingane ezisebenzise i-akhawunti zingakapheli amashumi amabili, kuzoba lula ukuyiqonda nakweminye inqwaba. Manje lolu hlelo ludinga ukuthi ukuhlanganisa nokukhupha kwenziwe engqondweni, hhayi kukholomu. Kubalulekile ukukhombisa ingane ukuthi ingayenza kanjani.
Isibonelo:
43 + 25. Kumayunithi angu-3 sengeza amayunithi angu-5 futhi sibhala kancane ngaphandle kwesibonakaliso sokulingana, sishiya indawo yesibalo esisodwa. Bese-ke ku-4 kuthiwa bengeze 2 futhi uthole 68. Kubalulekile ukuthi ingane iqonde ngokucacile ukuthi inqwaba namayunithi ayikwazi ukudideka. Isibonelo esifanayo singaxazululwa kukholomu ngesimiso esifanayo.
Uma ingane ingakwazi ukuxazulula lezi zibonelo, kufanele ukhulume nomfundisi ukuze anake le nkinga. Kodwa ungathwali umthwalo wemfanelo futhi uzikhiphe - ufunde ekhaya, endaweni enokuthula maduze noma kamuva uzonikeza umphumela omuhle.
