Opvoeder se bladsy

Verdubbeling

  • Tel 1 teller / blokkie / boontjie met een hand op.
  • Tel dieselfde aantal met die ander hand op.
  • Hoeveel?
  • Hoeveel altesaam?
  • Ons kan sê: 1 + 1 = 2
  • Wat het ons gedoen?
  • Ons het dieselfde aantal in die ander hand geneem.
  • Ons sê: ONS HET EEN VERDUBBEL.
  • Een verdubbel is gelyk aan twee.
  • Volg dieselfde stappe met 2, 3, 4 en 5 sodat leerders die begrip verdubbeling verstaan.
  • Vra elkeen afsonderlik sodat vasgestel kan word of hy die woord “verdubbel” verstaan, en of hy die verdubbeling kan doen.
  • Hoe kan ons getalle verdubbel anders as om tellers te gebruik? Teken?
  • Kyk in die vertrek rond: Kan jy enige plek sien waar getalle verdubbel word?Bv. 4 vensters aan die linkerkant en 4 vensters aan die regterkant.Ligte?Liggaamsdele? – oë, ore, hande, voete, vingers, tone.

Halvering

Halvering beteken dat iets gelykop verdeel word tussen twee mense.

Op die mat bv.:

  • Neem 2 tellers.Verdeel hulle tussen 2 leerders.Hoeveel kry elkeen?Wat gebeur as ons die 2 tellers weer bymekaar sit? Ons sal 2 hê. Wat word dit genoem? Verdubbeling.
  • Neem 4 tellers.
  • Volg die stappe soos vir 2.
  • Neem 6.
  • Neem 8.
  • Neem 10

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 in:

1.2.1 ene vanaf enige getal tussen 0 en 200;

1.2.2 tiene vanaf enige veelvoud van 10 tussen 0 en 200;

1.2.3 vywe vanaf enige veelvoud van 5 tussen 0 en 200;

1.2.4 twees vanaf enige veelvoud van 2 tussen 0 en 200;

Assesseringstandaard 1.10: Dit is duidelik wanneer die leerder die volgende tegnieke gebruik:

1.10.1 opbou en afbreek van getalle;

1.10.2 verdubbeling en halvering;

1.10.3 gebruik van konkrete apparaat (bv. tellers);

1.10.4 getallelyne;

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

What is different between quantity demand and demand?
Shukri Reply
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded
