Hierdie is verrykingswerk en as u dit te gevorderd vind, kan dit in 'n later stadium gedoen word. Daar mag wel leerders wees wat die uitdaging sal aanvaar.

Aangesien 3 x en ÷ pas voltooi is, is dit maklik om derdes nou aan te pak.

Gee aan die leerders los vorms van papier en laat hulle vou en meet en self ontdek hoe dit gedoen kan word. Sommige van die leerders sal self weet hoe om nou sesdes te kry. (Slegs verryking)

Die idee van die resep is om die leerders te laat besef dat die gebruik van standaard meeteenhede en houers noodsaaklik is.

Laat die leerders nog voorbeelde noem waar standaard meeteenhede om inhoud te meet daagliks gebruik word, bv. brandstof, melk, meng van bestanddele vir medisyne, voorskrifte vir toediening van medikasie, ens.

Dit is noodsaaklik dat al die verskillende standaard maathouers en skale, asook sand, water en ander voorwerpe om inhoud en massa te meet, in die klas beskikbaar moet wees. Die leerders moet daagliks kan eksperimenteer met hierdie standaard meeteenhede: liter en milliliter en gram en kilogram .

'n Badkamerskaal is nodig om die leerders se massas te bepaal.

Verskillende metodes word gebruik vir die vermenigvuldig- en deelbewerkings, maar indien u van 'n ander metode gebruik maak en die leerders dit beter verstaan, is dit hulle reg om die metode wat hulle verkies, te gebruik.

Dit is noodsaaklik dat baie soortgelyke voorbeelde van die betrokke getalsinne eers mondeling gedoen word, voordat van die leerders verwag kan word om hierdie werkvel te voltooi.

Die volmaak van 'n honderd en die ontbinding van 'n honderd word nou formeel aangeleer. Baie konkrete werk moet vooraf gedoen word. Meer gevorde werk waar 'n tien en 'n honderd gelyktydig oorgedra of ontbind word, moet nie op dieselfde tyd gedoen word nie. Dit sal van die groep se vermoëns afhang of dit net hierna of op 'n baie later stadium gedoen moet word.

Dit bly die opvoeder se keuse of die leerders hulpsyfers by die vertikale bewerkings gaan gebruik.

Leerders sal 'n skoon vel papier nodig hê om die korste pad te bereken. Sommige leerders mag dit moeilik vind, maar met 'n bietjie hulp, behoort hulle dit te kan doen.

'n Bespreking oor wat hulle sal sien, afhangende van die rigting waaruit hulle na die huis aangery kom, is nodig voordat die leerders dit kan teken.

Leerders afdeling

Inhoud

Aktiwiteit: om tyd te leer lees [lu 4.1, lu 4.2]

  • Bonnie en Tommie het elkeen 'n horlosie vir hul verjaardag gekry.

Neem 'n papierbord of sny 'n sirkel uit karton en ontwerp jou eie horlosie waarmee jy kan leer om tyd te lees.

Onthou:

1 dag = 24 uur

1 uur = 60 minute

1 minuut = 60 sekondes.

  • Hoe laat is dit?
  • Teken die lang en kort wysers in op die horlosies:
  • Bonnie en Tommie het om twee-uur by 'n maatjie gaan speel en was weer om vyfuur by die huis. Hoeveel ure was hulle weg?

Hulle was ____________________________________________________________

  • 'n Uur kan ook in 2 halfure gedeel word.

1 uur = 60 minute

'n halfuur = 30 minute

  • Hoe laat is dit?
  • Teken die lang en die kort wysers in op die horlosies:

  • Bonnie en Tommie doen elkeen 8 somme in 'n halfuur.

Hoeveel somme sal hulle altesaam in 1 uur doen?

Hulle sal _____________________________________________________________

  • Mamma ry 50 km in 'n halfuur. Hoe ver sal sy in 2½ uur ry?

Sy sal _______________________________________________________________

  • Hoeveel halfure is daar in 4 ure? 4 ure = ______________________ halfure
  • 'n Uur kan ook in 4 kwarte gedeel word. Dan het jy 4 kwartiere.

1 uur = 60 minute

'n halfuur = 30 minute

‘n kwartier = 15 minute

  • Hoe laat is dit?

  • Teken die lang en kort wysers in op die horlosies:
  • Voltooi die tabel:
kwartiere 1 2 3 4 5 6 7 8
minute 15 30

  • Hoe laat is dit?

  • Teken die lang en kort wysers in op die horlosies:

  • Mamma het om 3-uur winkel toe gegaan en was weer om 20

oor 4 terug by die huis. Hoe lank was sy weg?

Sy was ______________________________________________________________

  • Bonnie kan elke 5 minute 3 bladsye van haar boek lees. Hoeveel bladsye kan sy in 1 uur lees?

Sy kan _______________________________________________________________

  • Pappa het 5 oor 2 by die bank ingegaan en 45 minute later weer uitgekom. Hoe laat was dit toe hy uitgekom het?

Dit was ______________________________________________________________

Assessering

Leeruitkomste 4: Die leerder is in staat om gepaste meeteenhede, instrumente en formules in 'n verskeidenheid kontekste te gebruik.

Assesseringstandaard 4.1: Dit is duidelik wanneer die leerder analoog- en digitale tyd in ure, halfure, kwartiere en minute lees;

Assesseringstandaard 4.2: Dit is duidelik wanneer die leerder probleme oplos wat berekeninge met en herleiding behels.

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.

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

name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world

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?
