## Inhoud

### AKTIWITEIT: Om hoofrekene te doen [LU 1.9.3]

• Kom ons speel ’n speletjie!

Speel saam met ’n maat. Julle het ’n dobbelsteen en 16 merkers vir elkeen nodig. Maak ook vir julle twee borde van stywe karton wat so lyk:

• Elke speler skryf nou die volgende getalle in op sy/haar bord. Jy mag hulle plaas net waar jy wil.

20 ; 24 ; 32 ; 39 ; 40 ; 41 ; 48 ; 57 ; 59 ; 61 ; 66 ; 68 ; 69 ; 79 ; 86 ; 90

• Wanneer julle gereed is, gooi nr. 1 die dobbelsteen.
• Die getal wat op die dobbelsteen verskyn, is die RES wat jy kry as jy ’n getal op die bord deel deur 7. Maak daardie getal toe met een van jou merkers. Maak beurte om te speel. Die een wie se bord eerste vol merkers is, is die wenner.

## 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 1.9: Dit is duidelik wanneer die leerder handberekeninge uitvoer wat die volgende behels:

1.9.3: (addisioneel) deling met klein getalle.

(3)

3. Skat die kwosiënt deur eers die deeltal af te rond tot die naaste 100 en dan die deler tot die naaste 10:

3.1 2 468 ÷ 47 = __________________________________________

= _______________________________________(2)

3.2 3 639 ÷ 33 = __________________________________________
