Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

Memorandum

1. 14 856 kg – (235 + 39 kg)

= 5 691 kg

2. (10 000 kg – 9 165 kg) ÷ 39

= 21,41

= 21 sakke

Inhoud

AKTIWITEIT: Om te bereken deur bewerkings te kies wat geskik is om probleme op te los [LU 1.8.2, LU 1.8.4]

Om getalsinne te skryf om ‘n probleemsituasie te beskryf [LU 2.4]

Werk hierdie keer op jou eie. Lees die onderstaande probleme deur en kyk of jy die oplossings daarvoor kan vind. Onthou jou getalsinne! Onthou ook jou netjiese, duidelike bewerkings, en moenie die eenhede vergeet nie!

1. ’n Vragmotor vervoer 235 sakke sand van 39 kg elk. Indien die vragmotor met sy vrag 14 856 kg weeg, wat is die massa van die vragmotor sonder vrag?

2. Dit is ’n 10 ton vragmotor (mag maksimum 10 ton vervoer). Hoeveel sakke kan nog opgelaai word sonder om die massagrens te oorskry?

Assessering

Leeruitkomste 1:Die leerder is in staat om getalle en die verwantskappe daarvan te herken, te beskryf en voor te stel, en om tydens probleemoplossing bevoeg en met selfvertroue te tel, te skat, te bereken en te kontroleer.

Assesseringstandaard 1.8: Dit is duidelik wanneer die leerder skat en bereken deur geskikte bewerkings vir die oplossing van probleme in verband met die volgende te kies en te gebruik:

1.8.2: optel en aftrek van heelgetalle;

1.8.4: vermenigvuldiging van minstens 4-syferheelgetalle met 3-syferheelgetalle;

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 2.4: Dit is duidelik wanneer die leerder getalsinne skryf om ‘n probleemsituasie te beskryf, insluitend probleme binne kontekste wat gebruik kan word om ‘n bewustheid van menseregte-, sosiale, ekonomiese, kulturele en omgewingsake te bevorder.
