Assessering

Leeruitkomste 4:Die leerder is in staat om gepaste meeteenhede, instrumente en formules in ‘n verskeidenheid kontekste te gebruik.

Assessment Standard 4.1:Dit is duidelik wanneer die leerder probleme oplos wat tyd, afstand en spoed behels;

Leeruitkomste 5:Die leerder is in staat om data te versamel, op te som, voor te stel en krities te ontleed om gevolgtrekkings en voorspellings te maak en om toevallige variasie te interpreteer en te bepaal.

Assesseringstandaard 5.5: Dit is duidelik wanneer die leerder data organiseer (en groepeer ook, waar gepas) en aanteken deur tellings, tabelle en stam-en-blaar-voorstellings te gebruik;

Assesseringstandaard 5.8: Dit is duidelik wanneer die leerder ‘n verskeidenheid grafieke met die hand of met behulp van tegnologie teken om data voor te stel en te interpreteer (gegroepeer en ongegroepeer);

Assesseringstandaard 5.9: Dit is duidelik wanneer die leerder data wat op verskeie maniere voorgestel is krities lees en interpreteer ten einde gevolgtrekkings en voorspellings te maak wat sensitief is.
