Kopkrapper!

In 1617 het Lord John Napier die volgende tabel vir vermenigvuldiging in Skotland gebruik:

456 × 8 het hy so bereken:

Sy antwoord was 3 648.

1. Werk saam met ’n maat. Kan julle sy metode verduidelik?

_____________________________________________________________________

_____________________________________________________________________

2. Gebruik nou die tabel en bereken:

2.1 698 x 5

= ___________________

2.2 687 x 9

= ___________________

2.3 Hoe sou julle 6 437 x 382 met behulp van die tabel bereken?

= ___________________

2.4 Gee nou vir jou maat ’n som om met behulp van die tabel uit te werk! Skryf jou som, die berekening en die antwoord hieronder neer.

2.5 Kontroleer jou maat se som.

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 1.11: Dit is duidelik wanneer die leerder ‘n verskeidenheid strategieë gebruik om oplossings te kontroleer en die redelikheid van oplossings te beoordeel.

Leeruitkomste 2: Die leerder is in staat om patrone en verwantskappe te herken, te beskryf en voor te stel en probleme op te los deur algebraïese taal en vaardighede te gebruik.

Assesseringstandaard 2.6: Dit is duidelik wanneer die leerder deur bespreking en vergelyking, die ekwivalensie van verskillende beskrywings van dieselfde verwantskap of reël wat soos volg voorgestel word bepaal:

2.6.3: met getallesinne.
