Inhoud

Aktiwiteit: om plekwaarde van syfers te herken [lu 1.4.1]

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

1. Kom ons kyk of jy jou kennis in verband met honderdduisende kan toepas. Vul die volgende getalle korrek in die tabel in:

HD TD D H T E
1.1 60 980 ___ ___ ___ ___ ___ ___
1.2 508 136 ___ ___ ___ ___ ___ ___
1.3 Vyfhonderd en vierduisend seshonderd ___ ___ ___ ___ ___ ___
1.4 Agthonderd ses en twintigduisend en veertig ___ ___ ___ ___ ___ ___
1.5 Vierhonderd en seweduisend en vyf ___ ___ ___ ___ ___ ___

2. As jy ‘n getallelyn goed kan “lees”, sal jy in staat wees om te bepaal presies waar om ‘n getal te plaas. Werk saam met ’n maat en gebruik pyltjies om aan te dui waar die volgende getalle min of meer op die getallelyn sal lê:

2.1 318 500

2.2 347 899

2.3 372 000

2.4 398 799

2.5 403 000

3. Jy het reeds in aktiwiteit 1.3 die geleentheid gehad om getalle in uitgebreide notasie te skryf. Kyk of jy dit ook met die volgende getalle korrek kan doen:

Bv. 26 113 = 20 000 + 6 000 + 100 + 10 + 3

3.1 576 826 =

3.2 894 392 =

Onthou jy nog?

= beteken is gelyk aan

¹ beteken is nie gelyk aan nie

<beteken kleiner as

Ø beteken groter as

Assessering

Leeruitkomste 1: Die leerder is in staat om getalle en hul verwantskappe te herken, te beskryf en voor te stel. Hulle kan ook met bekwaamheid en vertroue tel, skat, bereken en kontroleer tydens die oplos van probleme.

Assesseringstandaard 1.4: Dit is duidelik wanneer die leerder die plekwaarde van syfers herken in:

1.4.1 heelgetalle tot minstens 9-syfergetalle;

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.

How bacteria create energy to survive?
Muhamad Reply

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
