Maak baie seker dat die leerders nie die voorste getal van ‘n aftrekbewerking herbenoem nie. ( Dit is die rede waarom hulle later probleme ondervind as hulle ‘n bewerking waar ‘n groep van 10 ontbind moet word, kry. )

Voorbeeld: 76 - 12 = ______

Probeer dit!

Gooi 76 tellers, wat in tiene en ene gegroepeer is, in ‘n plastieksak.

Laat ‘n leerder nou 2 kom uithaal.

Vra : Hoeveel is in die sak oor? 74

Wat is gedoen? ( 2 ene is uitgehaal) Skryf : 76 - 2 = 74

Laat ‘n ander leerder nou die 10 kom uithaal.

Vra : Wat is nou oor in die sak? 64

Wat is gedoen? ( 1 tien is uitgehaal) Skryf : 74 - 10 = 64

Om te toets, word eers 10 en dan 2 weer terug in die sak gegooi. Nou is daar weer 76 .

Onthou : Alle bewerkings word nog sonder oordrag of ontbinding van ‘n tien gedoen.

Leerders kan horisontaal of vertikaal werk. Dit is hulle keuse.

Help die leerders net om aan die gang te kom met die ontsyfering van die geheime kode. Hulle moet net begryp dat elke teken ‘n letter van die alfabet voorstel. Los hulle dan om self te probeer.

Moedig almal aan om iets met die kode te skryf, al is dit net hul eie naam.

Dit is ook ‘n geleentheid om uit te vind wie reeds die alfabet ken. Dalk kan dit sommer dien as aansporing om dit te leer.

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 1.1: Dit is duidelik wanneer die leerder aan en terug tel in:

1.1.1 die intervalle aangedui vir graad 2 met toenemende getalomvang;

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

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 1.10: 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 getallelyne;

1.10.4 afronding in tiene.

I don't think so. because check it, if the demand for chicken increases, people will no longer consume fish like they used to causing a fall in the demand for fish

Suppose the inflation rate is 6%, does it mean that all the goods you purchase will cost 6% more than previous year? Provide with reasoning.
Geetha Reply
Not necessarily. To measure the inflation rate economists normally use an averaged price index of a basket of certain goods. So if you purchase goods included in the basket, you will notice that you pay 6% more, otherwise not necessarily.
