1. Kyk na die tiene-syfer. Indien 5 of meer, maak honderde-syfer een meer. Indien 4 of minder, bly honderde-syfer dieselfde. Vervang tiene en ene-syfers met nulle

2. honderde

duisende word een meer

honderde, tiene en ene

Aktiwiteit: om te bereken deur bewerkings te kies wat geskik is om probleme op te los[lu 1.8.1]

1. In Graad 5 het ons herhaalde kere gesien hoe noodsaaklik dit is om korrek te kan afrond. Dit kan ons onder andere help om benaderde antwoorde vinnig, sonder potlood-en-papier-bewerkings, te kry.


  • Kom ons hersien
  • Verduidelik aan jou maat hoe rond ons af tot die naaste 100.

2. Kyk of jy die volgende op jou eie kan voltooi:

As jy dit nie self kon regkry nie, vra ’n maat om jou te help.

3. Voltooi die volgende tabel:

getal afgerond tot die naaste 100 afgerond tot die naaste 1 000
3.1 7 995
3.2 47 216
3.3 150 505
3.4 3 409 235
3.5 5 630 981


  • Kan jy die volgende afrond tot die naaste 10 000?

i) __________________________________________________________________

Prys R89 895

ii) __________________________________________________________________

Prys R13 995


Hoe goed verstaan jy die voorafgaande werk? Assesseer jouself op ‘n skaal van 1 tot 4. Omkring die toepaslike kode.

1 = benodig aandag

2 = redelik goed

3 = baie goed

4 = uitstaande

Kriteria: Kode
Ek kan 7-syfergetalle korrek uitspreek. (LU 1.3) 1 2 3 4
Ek kan 7-syfergetalle korrek in woorde neerskryf. (LU 1.3) 1 2 3 4
Ek kan die waarde van syfers in ’n getal korrek bepaal. (LU 1.4) 1 2 3 4
Ek verstaan hoe die magte van 10 werk en kan dit korrek toepas. (LU 1.10) 1 2 3 4
Ek kan korrek afrond tot die naaste 100. (LU 1.8) 1 2 3 4
Ek kan korrek afrond tot die naaste 1 000. (LU 1.8) 1 2 3 4
Ek kan korrek afrond tot die naaste 10 000.(LU 1.8) 1 2 3 4


Leeruitkomste 1: Die leerder is in staat om getalle en hul verwantskappe te herken, te beskryf en voor te stel. Hulle kan ook met bekwaamheid en vertroue tel, skat, bereken en kontroleer tydens die oplos van probleme.

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:

1.8.1: afronding tot die naaste 5, 10, 100 of 1 000.

Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
