Inhoud

Aktiwiteit: om die skryfwyses van verskillende kulture te beskryf en te illustreer [lu 1.2]

  • Kan jy hieruit aflei hoe die Romeine 11 sou skryf?

_____________________________________________________________________

1.2 Hoe sou hulle 15 skryf?

_____________________________________________________________________

1.3 Waar word hierdie Romeinse syfers vandag nog gebruik?

_____________________________________________________________________

  • Kyk ook goed na die volgende:
Ons: 10 20 30 40 50 60 70 80 90 100
Romeine: X XX XXX XL L LX LXX LXXX XC C
Ons: 100 200 300 400 500 600 700 800 900 1 000
Romeine: C CC CCC CD D DC DCC DCCC CM M

2. Gebruik nou die bostaande inligting en bereken die volgende.Skryf jou antwoord in Romeinse syfers:

  • 40 + 2 ________________________________________________________

2.2 90 + 9 ________________________________________________________

2.3 2 000 + 500 + 50 _______________________________________________

3. Jy het nou so pas geoefen om soos die Romeine te skryf. Hieronder is nog ‘n paar voorbeelde van hoe hulle ‘n sekere getal sou skryf. Kan jy dit in gewone (ons) syfers skryf?

3.1 DCVIII ________________________________________________________

3.2 LXV ________________________________________________________

3.3 MMMCCLVII __________________________________________________

4. Kan jy ons huidige jaartal in Romeinse syfers skryf?

Kopkrapper!

Die volgende vuurhoutjies is in Romeinse syfers gepak, maar die antwoorde is verkeerd. Kan jy deur net EEN vuurhoutjie te skuif, die som “regmaak” sodat die antwoord korrek sal wees?

TYD VIR SELFASSESSERING

Beoordeel jouself op ‘n skaal 1 – 4 deur net ‘n sirkel te trek wat waar is van jou:

Ek kan Glad nie Soms Meeste van die tyd Altyd
my sakrekenaar se konstante funksie gebruik vir herhaalde optelling. 1 2 3 4
Romeinse syfers neerskryf vir ons syfers. 1 2 3 4
Optel en die antwoord in Romeinse syfers gee. 1 2 3 4
Romeinse syfers in gewone syfers skryf. 1 2 3 4

Die Romeinse telstelsel raak egter baie ingewikkeld. Die desimale stelsel wat ons gebruik, is meer prakties. Kom ons kyk nou na die verskillende maniere waarop ons kan optel.

ONTHOU JY NOG?

  • Die antwoord van ’n optelsom word die SOM VAN die twee getalle genoem.
  • Die INVERSE (omgekeerde) bewerking van optelling is AFTREKKING.

HET JY GEWEET?

Die volgorde waarin getalle opgetel word, maak geen verskil aan die antwoord nie!

Byvoorbeeld: 5 + 4 = 4 + 5
9 = 9
So ook: (16 + 14) + 12 = 16 + (14 + 12)
30 + 12 = 16 + 26
42 = 42

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 1.2: Dit is duidelik wanneer die leerder verskeie maniere beskryf en illustreer om getalle neer te skryf deur die geskiedenis heen in verskillende kulture (insluitend plaaslik).

how did psychology begin?
Valerie Reply
of psychologys commencement, the traces can be seen in the work of Aristotle, where he talk about soul and body, likewise work in durrant, de anima, all these were somewhere supporting dualism, in which soul could exist separately from body

To pursue a career as a psychotherapist you'll have to do your bachelors in psychology. (bsc honors is preferable). since there are many fields and you've chosen as a therapist. a masters degree in clinical psychology or therapy and family counseling is preferable.

hae everyone, hope you are well this evning my question is what is the difference between drive and motivation
Michael
good question
Rainee
drive is more like an impulse or urge and i think they both go together (drive and motivation) even if there is a slight difference
edem
@ Michael Drive is delivered to be innate without the use of an external stimuli, motivation normally evolves an outside stimuli which may include praise, appreciate, or reward.
Reginald
*believed...sorry for typo

@Reginald, can't the motivation come from the inner self?

You mean who is the father of having a great educated argumentative guess? nothing is more wrong than this question. The question is you should ask yourselfs is, how sure are you abour their scientific studying? one's percieved assimilated approach to judging another person and saying they are
Roger
the biggest problem with scientific research and data is that ya you could get the same result 1000 times then it could go the other way 1000 times, but we would never know that and we did, we would still say ya but the proof is there. The only thing science proves is that humanity has
Roger
no facts about human behavior in the scientific context, but more in the trial and error.. sorry to tell you, but so far no one has proven Father of anything, thats up to you and i, judgement is bias, science is good enough lazy

Anyone knows about Techno-fascism?
Hussein Reply
Ecofascism is a theoretical political model in which an authoritarian government would require individuals to sacrifice their own interests to the "organic whole of nature". The term is also used as a rhetorical pejorative to undermine the environmental movement.

what's the big difference between prejudice and discrimination?
Danice Reply
A prejudiced person may not act on their attitude.  Therefore, someone can be prejudiced towards a certain group but not discriminate against them.  Also, prejudice includes all three components of an attitude (affective, behavioral and cognitive), whereas discrimination just involves behavior
