## 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 aan en terug tel;

Assesseringstandaard 1.7: Dit is duidelik wanneer die leerder praktiese probleme oplos wat gelyke verdeling en groepering behels, en verduidelik die antwoorde wat eenheidsbreuke kan insluit;

Assesseringstandaard 1.8: Dit is duidelik wanneer die leerder die gepaste simbole in berekeninge gebruik om probleme op te los:

Assesseringstandaard 1.9: Dit is duidelik wanneer die leerder hoofberekeninge uitvoer;

Leeruitkomste 2: Die leerder is in staat om patrone en verwantskappe te herken, te beskryf en voor te stel en probleme op te los deur algebraïese taal en vaardighede te gebruik.

Assesseringstandaard 2.3: Dit is duidelik wanneer die leerder eie patrone skep;

Assesseringstandaard 2.4: Dit is duidelik wanneer die leerder patrone wat waargeneem is beskryf;

Assesseringstandaard 2.5: Dit is duidelik wanneer die leerder meetkundige patrone in natuurlike en kulturele voorwerpe uit verskillende kulture en tye identifiseer, beskryf en kopieer.

Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
