Inhoud

Aktiwiteit: om hoofrekene te kan doen [lu 1.8.2]

Kompetisie tyd!

  • Kompeteer teen ’n maat en kyk wie kan die volgende pyldiagram eerste KORREK voltooi. Jy mag nie ’n sakrekenaar gebruik nie.

Die merkwaardige miljoen!

Jy weet reeds:

10 x 10 = 100

100 x 10 = 1 000

1 000 x 10 = 10 000

10 000 x 10 = 100 000

Kyk goed na die patroon hierbo en vul in:

100 000 x 10 = ______________________________________________________

Korrek! 100 000 x 10 = 1 000 000

Ons lees: 1 000 000 eenmiljoen

  • In the notation column it looks like this:
Miljoen Honderdduisend Tienduisend Duisend Honderd Tien Een
M HD TD D H T E
1 000 000 100 000 10 000 1 000 100 10 1
  • Kom ons lees die groot getalle

4 721 568 word gelees as 4 miljoen 721 duisend 568

Dus: viermiljoen sewehonderd een en twintig duisend vyfhonderd ag en sestig

Let op!

Ons groepeer die syfers drie-drie van agter af.

Die eerste spasie van links sê vir ons hoeveel miljoene daar is. Die tweede spasie van links dui aan hoeveel duisende daar is.

Bv. 3 (miljoen) 268 (duisend) 413

Assessering

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.
