Bonnie en tommie kyk na die seisoene

Opvoeders afdeling

Memorandum

Die module maak steeds voorsiening vir konsolidering, vaslegging en assessering van werk wat in die vorige grade onderrig is, met spesiale aandag aan die getal 100.

Getalbegrip tot 200.

Bewerkings: – Konsolideer alle werk gedoen in Grade 1 en 2.

Die name van die maande en die korrekte skryfwyse moet aandag geniet. Gesprekke rondom die seisoene en ‘n gesonde omgewing (Natuurbewaring) sorg vir integrering met ander leerareas.

Weerkaarte van die verskillende seisoene kan gehou word, bv. Februarie – somer; Mei – herfs; Augustus – winter; November – lente. Dit is nie die beste maande van die betrokke seisoene nie, maar dit is die maande waartydens die leerders die hele maand skool bywoon. Voltooi elke keer ‘n blokgrafiek aan die einde van die weerkaart, sodat die weersomstandighede vergelyk en bespreek kan word. Sodoende kan die blokgrafieke aan die einde met mekaar vergelyk word en die leerders kan self ontdek watter weersomstandighede eie aan hul eie omgewing en ook eie aan elke seisoen is. Die opvoeder kan die betrokke jaar se grafieke bêre om dit dan met die volgende jaar se grafieke te vergelyk.

Die take en aktiwiteite in Module 2 is nog hoofsaaklik gemik op konsolidasie en vaslegging van die werk van die vorige grade. Dit is egter noodsaaklik dat daar steeds van konkrete apparaat gebruik gemaak sal word om alle begrippe wat nie baasgeraak is nie te herhaal, te verduidelik en vas te lê.

Dit is van die allergrootste belang dat die leerders heeltemal vertroud moet wees met die tiene-groepering van ons getalstelsel:

10 ene word gegroepeer as 1 groep van tien

10 groepe van tien word gegroepeer as 1 groep van honderd

10 groepe van honderd word gegroepeer as 1 groep van duisend , ens.

Leerders moet werk met tellers wat in honderde , tiene en ene gegroepeer is. Indien daar nie tellers beskikbaar is nie, kan van die volgende semi-konkrete apparaat gebruik gemaak word.

Die spreikaarte is baie handig wanneer plekwaardes, herbenoeming, vereniging van getalle en die 0 as plekhouer verduidelik word.

Aangeheg is 'n voorbeeld van spreikaarte en 'n sleutel vir die skrywe van alle getalname. Met die spreikaarte kan die leerders enige getal bou en indien die leerders die basiese getalname ken, kan hulle enige getalnaam uit die dele opbou en skryf. Rol dit af en gee dit aan elke leerder om by hom te hou.

Voorbeeld:

Getalnaam: eenduisend eenhonderd sewe en dertig

Indien u hierdie voorbeeld wil gebruik, vergroot dit en rol dit dan af op manilla.

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?

or infinite solutions?

The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?

not now but maybe in future only AgNP maybe any other nanomaterials

this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
