### AKTIWITEIT: Om hoofreken te kan doen [LU 1.9.1, LU 1.9.2]

1. Jy het reeds in die vorige grade kennis geneem van die belangrikheid van die vermoë om hoofreken vinnig en akkuraat te kan doen. Kom ons kyk hoe vaar jy in jou eerste Graad 6-toets! Werk so vinnig en akkuraat moontlik:

1.1 56 + __________________ = 83

1.2 49 x 15 = __________________

1.3 12 x 8 = __________________

1.4 . __________________ ¸ 9 = 7

1.5 Halve 85: . __________________

1.6 Double 163: __________________

1.7 20 x __________________ = 2 000

1.8 (7 x 9) − 8 __________________

1.9 98 + 99 + 97 = __________________

1.10 1 004 − 12 = . __________________

1.11 8 x 9 x 6 = 6 x . __________________ x 9

1.12 A half x __________________ = 150

1.13.. (38 + 49) − 24 = __________________

1.14 89 __________________ 16 = 105

1.15 998 − __________________ = 550

Voltooi: Ek het _____________________________________ reg!!

HET JY GEWEET?

Kan jy nog onthou watter getallestelsel ons vandag gebruik?

____________________________________________________________________

Die Antieke Romeine het hulle telstelsel meer as 2 000 jaar gelede uitgevind en van hul syfers lyk so: I ; II ; III ; IV ; V

2. KOM ONS TEL!

Werk saam met ’n maat en maak beurte om te tel in:

2.1 tiene vanaf 19 870 tot 20 040

2.2 honderde vanaf 67 403 terug tot by 65 903

2.3 duisende vanaf 37 556 terug tot by 29 556

2.4 tienduisende vanaf 25 526 tot 95 526

## 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.

Assesseringstandaard 1.9: Dit is duidelik wanneer die leerder hoofberekeninge uitvoer wat die volgende behels:

1.9.1: optelling en aftrekking;

1.9.2: vermenigvuldiging van heelgetalle tot minstens 12 x 12.
