### AKTIWITEIT: Om ‘n reeks tegnieke te gebruik om berekeninge te doen [LU 1.10.2]

Kom ons kyk hoe goed jy nou jou bestaande kennis van deling kan toepas. Bereken die volgende sonder om ‘n sakrekenaar te gebruik. Jy mag enige metode wat jy verkies, gebruik!

1. t = 1 528 ÷ 24

KOPKRAPPER!

Tydens ’n kompetisie eindig die gr. 5, 6 en 7’s gelykop. 21 kanne koeldrank word vir hulle by die skool afgelewer. 7 van die kanne is heeltemal vol koeldrank en 7 is halfvol. 7 leë kanne word ook afgelaai.

Hoe kan jy die koeldrank tussen die 3 grade verdeel sodat almal ewe veel koeldrank en kanne kry? (Wenk: Maak ’n skets!)

TYD VIR SELFASSESSERING

Dit is belangrik dat ons sal weet hoe jy voel oor die gedeelte van die werk wat ons so pas afgehandel het. Evalueer jouself deur ‘n regmerkie in die toepaslike blokkie te maak:

 Ek kan die kwosiënt skat deur die deler en die deeltal af te rond. (LU 1.10) ____ ____ ____ ____ Ek kan die kwosiënt skat deur van verdubbeling gebruik te maak. (LU 1.10) ____ ____ ____ ____ Ek kan vermenigvuldiging gebruik en so die kwosiënt skat. (LU 1.10) ____ ____ ____ ____ Ek kan die kwosiënt voorspel deur na sekere patrone op my sakrekenaar te kyk. (LU 2.1) ____ ____ ____ ____ Ek kan korrek deel en ’n res bepaal sonder om my sakrekenaar te gebruik. (LU 1.11) ____ ____ ____ ____

** Vra jou opvoeder se hulp!

## 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 1.10: Dit is duidelik wanneer die leerder ‘n verskeidenheid tegnieke gebruik om sowel skriftelike as hoofberekeninge met heelgetalle te doen, insluitend:

1.10.2: langdeling.
