KOMPETISIE TYD!

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

Figure 1 (graphics1.png)

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:
Table 1
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
