Inhoud

Aktiwiteit: om vorentoe in intervalle te tel [lu 1.1]

Om getalle te herken, voor te stel, hul te beskryf en te vergelyk [lu 1.3]

1. KOM ONS JAAG RESIES!

Die volgende aktiwiteit sal jou help om jou vaardighede om dieselfde getal elke keer by te tel of af te trek, te verbeter. So leer jy ook sommer jou x-tafels, wat noodsaaklik is om korrek te kan vermenigvuldig en deel.

Werk saam met ’n maat. Julle het ’n stophorlosie nodig. Jy moet so vinnig as wat jy kan, die volgende lere "klim" deur die korrekte antwoorde te gee. Dan is dit weer jou maat se beurt. Die een wat dit die vinnigste KORREK kan doen, is die wenner! (Kontroleer met ‘n sakrekenaar).

BEGIN BO EN WERK TOT ONDER:

BEGIN NOU ONDER EN WERK OP:

Veelvoude

ONTHOU JY NOG?

Die antwoorde wat jy hierbo gekry het, noem ons VEELVOUDE van die 6x, 7x, 8x en 9x-tafel.

’n VEELVOUD is ’n getal wat ons kry as ons die gegewe getal (bv. 6) met ’n ander getal of ’n reeks getalle vermenigvuldig.

Bv. Die veelvoude van 5 is 5 ; 10 ; 15 ; 20 ; 25 ; ens.

2. Het jy geweet? Veelvoude help jou om breuke korrek op te tel! Dit is dus belangrik dat jy so gou as moontlik al die veelvoude van jou x-tafels sal ken. Kom ons oefen! Kleur die veelvoude van 12 in.

FAKTORE

HET JY GEWEET?

’n Faktor is ’n getal wat presies in ’n gegewe getal kan indeel.

As ons bv. getalle soek wat presies in 12 kan indeel, kry ons 1 ; 2 ; 3 ; 4 ; 6 en 12. Hierdie getalle is FAKTORE van 12.

Wenk: Dink in "pare"1 × 12 = 122 × 6 = 123 × 4 = 12

3. Dit is belangrik om voldoende kennis van faktore te hê, omdat dit jou kan help om korrek te deel en om breuke te vereenvoudig. Kyk of jy die tabel hieronder kan voltooi:

Getal Faktore
Bv. 8 1 ; 2 ; 4 ; 8
10 ..................................................
15 ..................................................
16 ..................................................
24 ..................................................
30 ..................................................

V ra ‘n maat om jou te assesseer!

  • Werk saam met ’n maat.
  • Beantwoord die volgende vrae en vra jou maat om ’n regmerkie in die toepaslike kolom te maak:

P riemgetalle

Let goed op:

’n PRIEMGETAL het net 2 faktore: 1 en die getal self.

How bacteria create energy to survive?
Muhamad Reply
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments

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
