1.1 K-S 50 km

S-C 60 km

C-S 70 km

S-H 70 km

H-R 20 km

R-M 35 km

1.2 ± 275 km

275 km ÷ 9 km = 30,35 = ± 30,5 ℓ

1.3 30,5 × R 5,80 = R 176,90

1.4 1 350 ÷ 100 = 13,5

13,5 × 140 = 1 890

= 1 890 treë

Inhoud

Aktiwiteit: om probleme in konteks op te los [lu 1.6.1, lu 1.6.2]

Om getalsinne te skryf om probleem-situasies te beskryf [lu 2.4]

1. Vir die volgende aktiwiteit kan jy ‘n maat kies om mee saam te werk. Lees die volgende probleme en los hulle op. Skryf netjiese getalsinne met duidelike bewerkings. Onthou jul eenhede!

1.1 Bestudeer die kaart met skaal en jou liniaal en bepaal die afstande tussen die verskillende dorpe / stede.

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 1.6: Dit is duidelik wanneer die leerder probleme oplos in konteks, insluitend kontekste wat gebruik kan word om ‘n bewustheid van ander leerareas, asook van menseregte-, sosiale, ekonomiese en omgewingskwessies, te bevorder soos:

1.6.1: finansiële kontekste;

1.6.2: meting in konteks van Natuurwetenskappe en Tegnologie;

Leeruitkomste 2: Die leerder is in staat om patrone en verwantskappe te herken, te beskryf en voor te stel en probleme op te los deur algebraïese taal en vaardighede te gebruik.

Assesseringstandaard 2.4: Dit is duidelik wanneer die leerder getalsinne skryf om ‘n probleemsituasie te beskryf, insluitend probleme binne kontekste wat gebruik kan word om ‘n bewustheid van menseregte-, sosiale, ekonomiese, kulturele en omgewingsake te bevorder.
