Blok- / Kolom- / Staafgrafiek

SIRKEL GRAFIEK

PRENTGRAFIEK / PIKTOGRAM

LYNGRAFIEKE

13.2 UITDAGING!

Werk in groepe van drie. Blaai deur jul plaaslike koerant en tydskrifte. Knip soveel moontlik verskillende soorte voorstellings van data uit. Sorteer / groepeer en plak dit netjies op karton. Hou ’n uitstalling hiervan en bespreek elke groep met die res van jul klas.

Assessering

Leeruitkomste 2: Die leerder is in staat om patrone en verwantskappe te herken, te beskryf en voor te stel en probleme op te los deur algebraïese taal en vaardighede te gebruik.

Assesseringstandaard 2.6: Dit is duidelik wanneer die leerder ‘n situasie beskryf deur ‘n grafiek daarvan te interpreteer, of ‘n grafiek van ‘n beskrywing van ‘n situasie teken (bv. Die hoogte van ‘n wipwaentjie oor tyd; die spoed van ‘n resiesmotor wat om ‘n baan beweeg).
