## Inhoud

### Om uitvoerwaardes vir gegewe invoer-waardes te bepaal [LU 2.3.1, LU 2.3.3]

Kon jy verduidelik hoe om die sakrekenaar te programmeer? Indien nie, vra ‘n maat om jou te help. As jy verstaan hoe dit werk, beantwoord die volgende vrae:

1. Sleutel in: 10 x 15 = = = =

Skryf elke keer jou antwoorde neer: ______________________________________

____________________________________________________________________

2. Waarom sê jou sakrekenaar uiteindelik 15 000 000 E? _________________

_____________________________________________________________________

3. Waarvoor staan die E? ________________________________________

4. Voltooi die volgende:

4.1 346 x 1 000 = 346 x 10o ___________________________________

4.2 346 x 100 000 = 346 x 10o _________________________________

4.2 346 x 10 000 000 = 346 x 10o _______________________________

5. Voltooi die volgende tabelle:

 5.1 1 × 25 25 2 × 25 _____ 5 × 25 _____ 8 × 25 _____ 12 × 25 _____
 5.2 1 × 100 100 ÷4 25 2 × 100 _____ ÷4 _____ 5 × 100 _____ ÷4 _____ 8 × 100 _____ ÷4 _____ 12 × 100 _____ ÷4 _____

6. Wat let jy op as jy na die antwoorde van hierdie twee tabelle kyk?

## 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 1.10: Dit is duidelik wanneer die leerder ‘n verskeidenheid tegnieke gebruik om sowel skriftelike as hoofberekeninge met heelgetalle te doen, insluitend:

1.10.5: gebruik van ‘n sakrekenaar;

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 2.3: Dit is duidelik wanneer die leerder uitsetwaardes bepaal vir gegewe insetwaardes deur gebruik te maak van:

2.3.1: woordelikse beskrywings.
