Inhoud

Aktiwiteit: om deelbaarheidsreëls te herken, te beskryf en te gebruik [lu 1.12.1]

Net soos by vermenigvuldiging, is daar sekere reëls vir deling deur veelvoude van 10 wat jou in staat stel om antwoorde in ‘n japtrap te bereken – sonder om potlood en papier te gebruik! Vir die volgende aktiwiteite moet julle in groepe van drie verdeel.

1. Kyk of julle reëls kan formuleer vir die volgende:

2. Deling deur 10: __________________________________________________

_______________________________________________________________

_______________________________________________________________

3. Deling deur 100: _________________________________________________

_______________________________________________________________

_______________________________________________________________

4. Deling deur 1 000: ________________________________________________

_______________________________________________________________

_______________________________________________________________

5. Deling deur 10 000: _______________________________________________

_______________________________________________________________

_______________________________________________________________

6. Vergelyk nou jul antwoorde met die res van die klas s’n!

7. Hoe vinnig kan jy nou die antwoorde van die volgende neerskryf SONDER om ’n sakrekenaar te gebruik?

GETAL ÷ 10 000 ÷ 1 000 ÷ 100 ÷ 10
Bv. 560 000 56 560 5 600 56 000

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 1.12: Dit is duidelik wanneer die leerder herken, beskryf en gebruik:

1.12.1: deelbaarheidsreëls vir 2, 5, 10, 100 en 1 000;
