Aktiwiteit: getalle [lu 1.3, lu 1.5, lu 1.6, lu 1.9, lu 3.6, lu 4.5]

Bonnie en Tommie is baie opgewonde oor die kermis. Daar gaan ver-skillende stalletjies wees en baie ander pret om aan deel te neem, asook hansworse om die mense te vermaak.

  • Teken 'n prent van hoe dit by julle skool sal lyk as julle kermis hou. Besluit vooraf watter stalletjies, pret en speletjies daar gaan wees en waar dit alles gaan plaasvind.
  • Bonnie en Tommie ken hulle getalle tot by 1 000 en wil nou verder tel.
  • Voltooi die getalleblok.
1001 1002 1003 1004 1005 1006 1007 1008 1009 1010

  • Watter getalle stel die diagramme voor?
  • Skryf die getalname van die getalle.

  • Bonnie en Tommie moet vinnig kan reken as hulle by die stalletjies wil help.
  • Bonnie gaan vir Mamma met die pannekoek help.
  • Die deeg in die houer is genoeg vir 100 pannekoeke. Hulle het beplan om 500 pannekoeke te bak. Teken al die houers wat nodig is vir die deeg.

Altesaam het hulle __________ ℓ deeg nodig.

  • Hoeveel ½ℓ (500 mℓ ) houers kan ons daarmee volmaak?

_____________________________________________________________________

  • Hulle gaan die pannekoeke teen R2 elk verkoop. Hoeveel geld sal hulle maak as hulle al die pannekoeke verkoop?

_____________________________________________________________________

  • Ons weet dat 10ℓ deeg vir ons 100 pannekoeke gee. Hoeveel pannekoeke kan ons van 1ℓ deeg bak?

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 1.3: Dit is duidelik wanneer die leerder getalsimbole en -name van 1 tot minstens 1 000 ken, lees en skryf;

Assesseringstandaard 1.5: Dit is duidelik wanneer die leerder die plekwaarde van syfers in heelgetalle tot minstens 3-syfergetalle herken;

Assesseringstandaard 1.6: Dit is duidelik wanneer die leerder geldprobleme oplos wat totale en kleingeld in rand en sent behels, insluitend herleiding tussen rand en sent;

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

Leeruitkomste 3: Die leerder is in staat om eienskappe van en verwantskappe tussen tweedimensionele vorms en driedimensionele voorwerpe in 'n verskeidenheid oriëntasies en posisies te beskryf en voor te stel.

Assesseringstandaard 3.6: Dit is duidelik wanneer die leerder informele kaarte van die skoolomgewing of van ’n groep driedimensionele voorwerpe lees, interpreteer en teken en dui die voorwerpe op die kaart aan;

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
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.
