Inhoud

Aktiwiteit: transformasies [lu 3.5, lu 1.8]

6. TRANSFORMASIES

6.1 Kyk weer na jou tessellasies by vraag 1 (c). Jy kon die tessellasies met ’n enkele driehoek votooi het, maar dan sou jy jou driehoek moes gly, draai of omdraai.

6.2 LET OP

Om van die swart na die wit driehoek te beweeg, gebruik ons die volgende transformasies:

gly

draai

omdraai

6.3 Werk saam met ’n maat. Trek een van die driehoeke af by vraag 1 (c). Knip dit uit en pas dit nou op jou tessellasies. Kyk waar jy die driehoek kan gly, draai of omdraai om die hele tessellasie te voltooi.

  • Bespreek jul bevindinge met die res van die klas.

6.4 Teken nou enige tessellasie waar jy van enige van die drie transformasies gebruik maak. Verduidelik jou tessellasie aan die res van die klas.

7. Tyd vir selfassessering

  • Merk die toepaslike blokkie met ’n regmerkie :
Ja Nee
Ek kon help om ’n 3-dimensionele model wat balanseer, te bou.
My gesig by vraag 1 (b) is simmetries.
Ek kon die tessellasies by vraag 1 (c) korrek voltooi.
Ek kon die breedte van my klas korrek in “el” bepaal.
Ek kan sketse korrek volgens skaal vergroot.
Ek kan sketse korrek volgens skaal verklein.
Ek kan die volgende begrippe verduidelik:
  • rotasie;
  • transformasies.
Ek kan bepaal hoeveel keer gegewe figure in ’n volle omwenteling roteer.
Ek kan tessellasies deur middel van transformasies teken.

8. Voltooi die volgende hoofrekentoets so vinnig en akkuraat moontlik:

a) 8 + 6 = _______________________

b) 28 + 9 = ______________________

c) 28 + 19 = _____________________

d) 58 + 39 = _____________________

e) 0,97 – 0,5 = ___________________

f) 1,97 – 1,5 = ___________________

g) 105 ÷ 10 = ____________________

h) 32 x 42= _______________________

i) 7 x 9 = ________________________

j) 70 x 9 = _______________________

k) 70 x 90 = ______________________

l) 700 x 900 = ____________________

m) 18 ÷ 6 = _______________________

n) 1 800 ÷ 60 = ___________________

o) 18 000 ÷ 600 = _________________

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 10 2 en derdemagswaardes van natuurlike getalle tot minstens 5 ³ 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 3.5: Dit is duidelik wanneer die leerder transformasies (rotasies, refleksies en verplasings) en simmetrie gebruik om die eienskappe van meetkundige figure te ondersoek (alleen en/of as ‘n lid van ‘n span of groep).

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
