Paheko Panoni
Paheko Panoni
He Kowae Ako Pāngarau
He kōwae ako e aro ana ki ētahi tikanga o ngā panoni nei, te hurihanga me te whakaatanga. Mātua rā ko te kōaro o tētahi panoni, me te whai o tētahi panoni i tētahi. Ka whakaaturia te hononga ki te marautanga, ngā whāinga ako, ngā rauemi ka whakamahia, te rārangi o ngā kupu matua, tae atu ki te raupapatanga o ngā mahi ako.
I tēnei kōwae ako ka tūhurangia te āhuatanga kōaro o ētahi panoni e rua, te tūmau me te kōaro o ngā panoni. Ka whai wāhi mai hoki te hangarite o ētahi āhua. He mea pūtake mai tēnei kōwae ako i te akoranga kei te pae tukutuku nei:

6. Ka tautohu, ka whakamārama, ka whakamahi i te hangarite o tētahi āhua ahu-2, āhua ahu-3.
7. Ka tautohu, ka whakamārama, ka whakamahi i ngā āhuatanga pūmau o ngā panoni.

Te Ine me te Āhuahanga
Whāinga Paetae 6 (Te Panoni):
Ka tautohu, ka whakamārama, ka whakamahi i te hangarite o tētahi āhua ahu-2, āhua ahu-3.
Whāinga Paetae 7 (Te Panoni):
Ka tautohu, ka whakamārama, ka whakamahi i ngā āhuatanga pūmau o ngā panoni.
Kia mōhio te ākonga ki:
- te whakaoti tūhuratanga pāngarau
- te tūmau me te kōaro o te paheko panoni
- te āhuatanga kōaro o te paheko panoni
Ina pāhekoheko tētahi huānga o tētahi pūnaha pāngarau me te huānga tūmau, ka pūmau tonu te huānga tuatahi, kāore e rerekē. Hei tauira:
- ko te ‘0’ te tūmau o te tāpiritanga me te tangohanga:
a + 0 = a a – 0 = a - Ko te ‘1’ te tūmau o te whakareatanga me te whakawehenga:
a x 1 = a a ÷ 1 = a
- ko te ‘0’ te tūmau o te tāpiritanga me te tangohanga:
Ina pāhekoheko tētahi huānga o tētahi pūnaha pāngarau me tōna kōaro, ko te huānga tūmau te hua. Hei tauira:
- ko te haere whakatetonga te kōaro o te haere whakateraki.
- Ko te –4 te kōaro o te +4 mō te tāpiritanga. Arā, +4 + –4 = 0 (ko te ‘0’ te tūmau mō te tāpiritanga)
- Ko te ¼ te kōaro o te 4 mō te whakareatanga. Arā, ¼ x 4 = 1 (ko te ‘1’ te tūmau mō te whakareatanga)
Ko te āhuatanga kōaro e mea ana kāore he take o te raupapa mai o ngā huānga o tētah paheko. He tauira:
- he āhuatanga kōaro tō te hurihanga. Kāore he take o te raupapa mai o te hurihanga ½, me te hurihanga ¼. Ko te hurihanga ¾ te hua.
- He paheko āhuatanga kōaro te tāpiritanga. Hei tauira, 3 + 4 = 4 + 3.
- Ehara te tangohanga i te paheko āhuatanga kōaro, arā, 3 – 4 ≠ 4 – 3.
