What is a lens?

Definition of a lens

Lenses

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.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

16. ‘n Ander tipe data

16.1 Het jy geweet?

Ons kan ook data versamel / inligting vind deur koördinate wat gegee word.

Kyk goed na die voorbeeld. Die kolletjie (λ) is by (4,7).

Die 4 dui die horisontale getal aan en die 7 die vertikale getal.

16.2 Teken die volgende op die eiland in.

16.3 Skryf die koördinate vir die roete wat ’n aantal leerders tydens ’n pretlloop gevolg het.

16.4 UITDAGING!

  • Skryf jou eie geheime boodskap! Gee jou koördinate vir ’n maat om te ontsyfer.

17. Het jy geweet?

17.1 Soms word die koördinate met kom­pas­aanwysings gekombineer om ’n sekere plek te vind.

Die lughawe sal jy vind by 3W, 3N. (W = wes ; N = noord)

18. Tyd vir selfassessering

Table 1
  • Merk die toepaslike kolom met ’n regmerkie:
Ja Sukkel nog
Ek kon die inligting by 14.1 deur middel van ’n lyngrafiek voorstel    
Ek kon ’n sirkelgrafiek trek by 14.2    
Ek kon die aantal stemme in die verkiesing by 14.3 korrek met ’n piktogram voorstel    
Ek kon ’n kolomgrafiek by 14.4 teken    
Ek kon ’n dubbele kolomgrafiek korrek by 14.5 teken    
Ek kon die vrae by 15.1 in verband met tyd korrek beantwoord    
Ek kon die gegewe skaal by 15.2 korrek interpreteer en vrae na aanleiding daarvan korrek beantwoord    
Ek kon gegewe koördinate op ’n kaart korrek interpreteer en die opdragte by 16.2 korrek uitvoer    
Ek kon die vrae na aanleiding van die kombinasie van koördinate en rigting korrek beantwoord (17.2)    

19. Kom ons kyk of jy volpunte kan kry vir jou laaste hoofrekentoets! Kyk sommer ook of jy al die vrae in minder as 2 minute kan beantwoord

a) 7³ = __________________________

b) 5² x 2³ = __________________________

c) 3³ x 104 = __________________________

d) 24 x 105 = __________________________

e) (4 x 7) ÷ (8 x 9) = __________________________

f) (12 x 9) ÷ (7 x 8) = __________________________

g) 16 ÷ 6 x 8 ÷ 19 = __________________________

h) (2 x 8 x 5 x 4 x 7) x 0 = __________________________

i) = __________________________

j) of 200 = __________________________

k) 0,3 = __________________________%

l) 25% of R592 = __________________________

m) (72 ÷ 9) ÷ (45 ÷ 9) = __________________________

n) (63 ÷ 7) x (54 ÷ 6) = __________________________

o) 92 – 9 x 4 – 28 = __________________________

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 1.8: Dit is duidelik wanneer die leerder hoofrekenberekeninge doen wat kwadrate van natuurlike getalle tot minstens 102 en derdemagswaardes van natuurlike getalle tot minstens 5³ behels.

Leeruitkomste 3:Die leerder is in staat om eienskappe van en verwantskappe tussen twee-dimensionele vorms en drie-dimensionele voorwerpe in ‘n verskeidenheid oriëntasies en posisies te beskryf en voor te stel.

Assesseringstandaard 3.8: Dit is duidelik wanneer die leerder posisie/ligging op koördinaatstelsels (geordende roosters) en kaarte bepaal.

Leeruitkomste 5:Die leerder is in staat om data te versamel, op te som, voor te stel en krities te ontleed om gevolgtrekkings en voorspellings te maak en om toevallige variasie te interpreteer en te bepaal.

Assesseringstandaard 5.9: Dit is duidelik wanneer die leerder data wat op verskeie maniere voorgestel is krities lees en interpreteer ten einde gevolgtrekkings en voorspellings te maak wat sensitief is.
