Inhoud

Aktiwiteit: om 2-dimensionele vorms te ondersoek en te vergelyk [lu 3.3.3]

‘n Kykie na sirkels

1. Kyk goed na die skets en beantwoord dan die vrae:

RQ = Middelyn

SP = Straal

1.1 Wat is ‘n sirkel?

_____________________________________________________________________

1.2 Waar, in ons alledaagse lewe, kry ons met sirkels te doen?

_____________________________________________________________________

_____________________________________________________________________

2. Beantwoord die volgende vrae:

2.1 Hoeveel middellyne kan ‘n sirkel hê? ___________________________

2.2 Hoeveel middelpunte kan ‘n sirkel hê? __________________________

2.3 Hoeveel strale (radius) kan ‘n sirkel hê?__________________________

3. Gebruik jou passer en trek ‘n sirkel met ‘n:

3.1 straal van 30 mm

3.2 middellyn van 80 mm

HET JY GEWEET?

Ons kan pragtige patrone met sirkels trek! Die patroon hieronder word “Paisley” genoem en word op klere of stukke lap gebruik.

4. Kan jy sien hoe die patroon geteken is? Probeer dit self!

5. Volg die volgende stappe en gebruik dan hierdie metode om die volgende patrone te teken. Jou opvoeder sal die nodige folio verskaf:

Teken ‘n sirkel

Gebruik dieselfde straal om die omtrek af te merk

Verbind nou die punte (indien nodig)

6. Ontwerp nou jou eie sirkel-patroon! Kleur dit netjies in:

Tyd vir selfassessering

Dit is belangrik dat ons sal weet of jy die werk wat ons tot dusver gedoen het, goed verstaan. Lees die onderstaande kriteria. Evalueer jouself op ‘n skaal van 1 – 4 deur ‘n sirkel om die toepaslike syfer te trek.

Kriteria 1 = Glad nie.2 = Net ‘n bietjie (min).3 = Goed.4 = Uitstekend.
Ek kan die term “ewewydig” verduidelik. 1 2 3 4
Ek kan die verskil tussen ‘n lyn en ‘n lynstuk verduidelik. 1 2 3 4
Ek kan die volgende begrippe verduidelik:
* skerphoek; 1 2 3 4
* stomphoek; 1 2 3 4
* regte hoek. 1 2 3 4
Ek kan hoeke akkuraat:
* met ‘n gradeboog meet; 1 2 3 4
* met ‘n gradeboog trek. 1 2 3 4
Ek kan die ooreenkomste tussen ‘n reghoek en ‘n parallelogram noem. 1 2 3 4
Ek kan die verskille tussen ‘n reghoek en ‘n parallelogram noem. 1 2 3 4
Ek kan die begrip “simmetries” verduidelik. 1 2 3 4
Ek kan die term “rotasie-simmetrie” verduidelik. 1 2 3 4
Ek kan die volgende begrippe verduidelik:
* straal; 1 2 3 4
* middellyn. 1 2 3 4
Ek kon die figure vergroot en verklein. 1 2 3 4
Ek kan patrone met sirkels teken. 1 2 3 4

Kom ons kyk na 3-Dimensionele figure.

Jy het seker al baie met ‘n dobbelsteen gespeel. Kyk of jy jou eie een kan maak. Trek die volgende ontvouing net so af. Knip dit uit en vou jou dobbel-steen. Skryf dan die nommers 1 – 6 op die kante. Onthou dat die nommerpare (1,6); (3,4) en (2,5) op die teenoorgestelde kante moet wees.

HET JY GEWEET?

Die dobbelsteen wat jy so pas gemaak het, is ‘n voorbeeld van ‘n kubus .

Assessering

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 3.3: Dit is duidelik wanneer die leerder twee-dimensionele vorms en drie-dimensionele voorwerpe wat in hierdie graad bestudeer word, ondersoek en vergelyk (individueel en/of as lid van ‘n groep), volgens die bostaande eienskappe deur die volgende te doen:

3.3.3: gebruik ‘n passer om sirkels, patrone in sirkels en patrone met sirkels te teken.

explain how nature and nurture affect the development and later the productivity of an individual.
Amesalu Reply
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills

child interact with other kids under doc supervision. play therapy. speech therapy. Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game. string and beads game. the more you interact with the child the more effective
Jharna
results you'll get.. please consult a therapist to know what suits best on your child. and last as a parent. I know sometimes it's overwhelming to guide a special kid. but trust the process and be strong and patient as a parent.
