Inhoud

Aktiwiteit: om ‘n reeks tegnieke te gebruik om berekeninge te doen [lu 1.10.3]

Om uitvoer-waardes vir gegewe invoer-waardes te bepaal [lu 2.3.3]

In Graad 6 is dit baie belangrik om sekere strategieë te ontwikkel om vinnig by antwoorde uit te kom en so die lewe vir jouself te vergemaklik. Kom ons kyk na ‘n paar slim planne wat ons kan maak wanneer ons vermenigvuldig.

ONTHOU!

Wanneer jy met 25 vermenigvuldig, kan jy eers met 100 vermenigvuldig en dan deur 4 deel.

1. Kan jy die volgende skale balanseer deur die korrekte getalle in te vul?

1.1

1.2

1.3

2. Gebruik bogenoemde metode en bereken:

2.1 324 x 25 =

_____________________________________________________________________

_____________________________________________________________________

_____________________________________________________________________

2.2 1 436 x 25 =

_____________________________________________________________________

_____________________________________________________________________

_____________________________________________________________________

2.3 26 844 x 25 =

_____________________________________________________________________

_____________________________________________________________________

_____________________________________________________________________

KOPKRAPPER!

Kan ek eers deur 4 deel en dan met 100 vermenigvuldig? _____________________

Bewys jou antwoord:

1 436 x 25 =_____________________________________

=___________________________________________

=___________________________________________

3. Kyk goed na die volgende voorbeeld en voltooi dan die tabelle:

3.1 1 × 125 125
3 × 125 _____
5 × 125 _____
9 × 125 _____
3.2 1 × 1 000 1 000 ÷ 8 25
3 × 1 000 _____ ÷ 8 _____
5 × 1 000 _____  8 _____
9 × 1 000 _____  4 _____

4. Vergelyk die antwoorde in die tabelle. Wat merk jy op?

_____________________________________________________________________

_____________________________________________________________________

_____________________________________________________________________

5. Voltooi die volgende:

ONTHOU:

As ek met 125 moet vermenigvuldig, kan ek eers met __________________

vermenigvuldig en dan die antwoord wat ek kry, deur ________________ ________________________ OF ek kan eers die getal deur _________________________deel en dan die antwoord met ______________. _______________

6. Kyk of jy dié metode kan toepas:

6.1 288 x 125 = ÷288  8) x 1 000

= _______________________

= _______________________

or

288 x 125 = ÷288 x 1 000) ÷ 8

= _______________________

= _______________________

6.2 1 056 x 125 = ÷1 056 ÷ 8) x 1 000 of _____________________

= _______________________

= _______________________

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:

1.10.3: opbou en afbreek van getalle.

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:

2.3.3: tabelle.

explain assimilatory nitrate reduction
Esinniobiwa Reply
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
