Hoe om ‘n ruitnet te gebruik

‘n ruitnet

Om 'n spesifieke plek se ligging op 'n plan of kaart aan te dui, is baie maklik as daar 'n ruitnet is. Dit is lyne wat op die kaart ingetrek word wat die kaart in klein vierkantige blokkies verdeel. Aan die bokant van die kaart word elke blokkie dan 1, 2, 3, ens. genommer. Aan die kant van die kaart word die syfers A, B, C, ens. aangebring.

Ons gebruik dié letters en syfers dan om aan elke blokkie 'n naam te gee.

Voorbeeld:

1 2 3
A A
B B
C C
3 2 3

As jy nou wil aandui waar die vliegtuig geleë is, sê ons dit is geleë in blok B2 .

Aktiwiteit 1

Om ligging te bepaal deur die gebruik van ‘n ruitnet [lu 1.3, 1.4]

Dui die ligging van die volgende voorwerpe aan soos wat dit in die voorbeeld hierbo voorkom:

1. man ...............................................................................................................

2. boom ..............................................................................................................

3. hond ..............................................................................................................

4. huis ...............................................................................................................

Bestudeer die volgende ruitnet:

1 2 3 4 5
A e n r g l A
B j q b t p B
C w k v x d C
D c y o I v D
E h m f s a E
1 2 3 4 5

Bestudeer nou die volgende gekodeerde boodskap wat volgens die ruitnet se kode geskryf is en ontsyfer dit. 'n Kommapunt (;) dui die einde van 'n woord aan.

A1 C2; B3 A5 D2; D4 A2; C2 E5 E5 B5 E4 B4 E5 C5; C1 E5 E5 A3; B3 A5 D2; B1 D2

Skryf nou jou eie boodskap deur van die ruitenetkode gebruik te maak. Ruil jou geheime boodskap uit met 'n klasmaat en ontsyfer mekaar se boodskappe.

Assessering

Leeruitkoms 1: aardrykskundige ondersoek

Die leerder is in staat om ondersoekvaardighede te gebruik om aardrykskundige en omgewingsbegrippe en -prosesse te ondersoek.

Assesseringstandaard

Dis duidelik wanneer die leerder

1.3 simbole identifiseer wat in verskillende soorte kaarte gebruik word (insluitend planaansigte, ruitenet- en kaartsleutels).

1.4 plekke se ligging vind deur ‘n eenvoudige ruitenetverwysingstelsel en rigting te gebruik.
