  • Integrasie van Temas: Vriende
  • Inklusiwiteit: Alhoewel elkeen van ons uniek is, is daar baie ooreenkomste; karaktereienskappe, sport, opvoeding ens.
  • Sosiale Geregtighede: Bespreek vriende se gedrag teenoor mekaar.
  • n Gesonde Omgewing: Wat is ons plig as aardbewoners om ons omgewing skoon te hou?

Opvoeder se bladsy

Die opvoeder sal bepaal of die leerders begrip van 1 meer verstaan deur die volgende op die mat te doen:

  • Pak 4 tellers uit. Maak dit 1 meer (‘n ander kleur). Hoeveel?
  • Doen dieselfde met 7, 3, 9, ens.
  • Hoeveel kinders is daar in die vertrek? Kry 1 meer – hoeveel is daar nou?
  • Laat 4 of 5 voor staan. Hoeveel kinders is daar? Een meer?
  • Neem nou waar terwyl soortgelyke stappe gevolg word om EEN MINDER te maak.

Probleemoplossing

  • Leerders moet dikwels met probleemoplossing gekonfronteer word, sodat hulle in staat kan wees om hul eie strategieë uit te werk.
  • Neem byvoorbeeld die probleem onderaan bladsy 15.
  • Stel ‘n soortgelyke probleem en neem waar hoe die leerders poog om dit op te los.
  • Bespreek die verskillende strategieë wat hulle volg.
  • Hulle mag tellers gebruik, prentjies teken of dit uit die hoof doen, ens.
  • Hulle moet in staat wees om hul strategieë in woorde te beskryf.
  • Bespreek verskillende strategieë.

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 1.9: Dit is duidelik wanneer die leerder hoofberekeninge uitvoer wat die volgende behels:

1.9.1 optelling en aftrekking van getalle tot minstens 20;

1.9.2 vermenigvuldiging van heelgetalle met oplossings tot minstens 20;

Assesseringstandaard 1.11: Dit is duidelik wanneer die leerder eie oplossings vir probleme verduidelik.

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?
ninjadapaul
hmm
Abhi
is it a question of log
Abhi
🤔.

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
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?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
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.
Ali Reply
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
