A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

Inhoud

AKTIWITEIT: Om die eienskappe van optelling te herken en te gebruik [LU 1.12.2]

1. Onthou jy nog dat ons in Graad 5 (Module 1) na die eienskappe van optelling gekyk het? Gebruik nou jou kennis!

Werk saam met ‘n maat en vind uit of die volgende waar of onwaar is. Jy mag jou sakrekenaar gebruik:

1.1 2 623 896 + 2 346 213 = 2 346 213 + 2 623 896

____________________________________________________________________

1.2 54 236 + (28 912 + 46 852) = (54 236 + 28 912) + 46 852

____________________________________________________________________

1.3 (128 435 + 239 416) + 1 379 538 = 128 435 + (239 416 + 1 379 538)

____________________________________________________________________

2. Voltooi die volgende sonder ’n sakrekenaar deur net die ontbrekende getalle in te vul:

2.1 456 213 + = 2 236 994 + 456 213

2.2 1 198 235 + (469 203 + 2 069 523) = (____________ + ____________)

+ 2 069 523

2.3 (264 059 + 3 016 438) + 1 269 055 = ____________ + (3 016 438 + ____________)

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

1.12.2: die kommutatiewe, assosiatiewe en distributiewe eienskappe van heelgetalle (leerders behoort in staat te wees om die eienskappe te gebruik sonder om noodwendig die name te ken).
