Inhoud

Aktiwiteit: om te bereken deur bewerkings te kies wat geskik is om probleme op te los [lu 4.5]

Kom ons kyk nou eers hoe goed jy nog kan optel en aftrek sonder ‘n sakrekenaar.

1. Verminder die volgende massa met 50 g:

1.1 2 916 kg = ________________________________ kg

1.2 2,048 kg = ________________________________ kg

1.3 0,800 kg = ________________________________ kg

1.4 26,132 kg = _______________________________ kg

2. Vermeerder die volgende massa met 300 g:

2.1 2,798 kg = ________________________________ kg

2.2 3,804 kg = ________________________________ kg

2.3 0,919 kg = ________________________________ kg

2.4 18,497 kg = _______________________________ kg

3. Bereken ook die volgende sonder ‘n sakrekenaar. (Wenk: maak eers die eenhede dieselfde.)

3.1 38,942 kg + 9,746 kg =

Assessering

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

Assesseringstandaard 4.5: Dit is duidelik wanneer die leerder probleme oplos wat die kies van, berekening met en herleiding tussen geskikte S.I.-eenhede (sien hierbo) behels, terwyl geskikte kontekste vir Tegnologie en Natuurwetenskappe geïntegreer word.
