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.

  • Evalueer elke voorstelling krities.

13.3 Tyd vir selfassessering

Table 1
  • Merk die toepaslike blokkie:
Onseker Seker
Ek kan die volgende begrippe verduidelik:    
  • data/statistiek
   
  • steekproef
   
  • modus
   
  • mediaan
   
  • rekenkundige gemiddelde
   
Ek kan minstens twee maniere noem om inligting te organiseer    
Ek kan uit gegewe inligting die volgende korrek bereken:    
  • modus
   
  • mediaan
   
  • rekenkundige gemiddelde
   
Ek kan minstens twee metodes noem om inligting te versamel    
Ek kan verduidelik wat die volgende is en hoe dit lyk:    
  • blok-/kolom-/staafgrafiek
   
  • lyngrafiek
   
  • sirkelgrafiek
   
  • prentgrafiek/piktogram
   
Ek kon die inligting by vraag 12.3 korrek versamel    
Ek kon die inligting by vraag 12.4 korrek versamel    

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).
