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.

advantage of electronic microscope is easily and clearly while disadvantage is dangerous because its electronic. advantage of light microscope is savely and naturally by sun while disadvantage is not easily,means its not sharp and not clear

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
Kenna Reply
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
