Opdrag 1:

Om ‘n elektroniese wiskundige speletjie te maak

LU/AS 1.2/1.7 – 1.9
LU/AS 1.10/1.12 – 1.13

Probleem:

Die leerders in gr.4 by Laerskool sukkel baie in die aanleer van tafels in Wiskunde.

Ontwerpvoorstel:

Ontwerp en maak ‘n oplossing vir hierdie probleem.

A. Skryf ‘n paar redes neer waarom ‘n oplossing vir hierdie probleem ‘n positiewe uitwerking op gr. 4-leerders se lewe sal hê.

Moontlike oplossings vir die probleem.

    • Ouers of ouer familielede moet beter vaslegging tuis doen.
    • Leerders moet elke dag ‘n tafeltoets by die skool skryf.
    • Ontwerp speletjies om vaslegging speel-speel te verseker.
  • Leerders skryf foute van tafeltoets 50 keer uit.

Assessering

Leeruitkomstes(LUs)
LU 1
Tegnologiese Prosesse en VaardighedeDie leerder is in staat om tegnologiese prosesse en vaardighede eties en verantwoordelik toe te pas deur gepaste inligtings- en kommunikasietegnologie te gebruik.
Assesseringstandaarde(ASe)
Dit is duidelik wanneer die leerder:
ondersoek :
1.2 bestaande produkte ondersoek wat toepaslik is vir ‘n probleem, situasie of behoefte gebaseer op die volgende kernaspekte van ontwerp.
ontwerp :
1.5 ‘n kort en duidelike stelling of ontwerpopdrag skryf of kommunikeer vir die ontwikkeling van ‘n produk of stelsel met betrekking tot ‘n gegewe probleem, behoefte of geleentheid;
1.7 minstens twee alternatiewe oplossings genereer en die idees annoteer;
1.8 moontlike oplossings kies, sinvolle redes vir keuse gee en ‘n gekose idee deur middel van grafika of modelleringstegnieke ontwikkel;
maak :
1.9 ‘n plan ontwikkel vir die maak van ‘n produk, met besonderhede oor al die volgende:
  • hulpbronne en hulpmiddels wat nodig is (bv. lyste materiaal, gereedskap, mense, koste);
  • sketse wat die nodige afmetings of hoeveelhede toon;
  • al die stappe wat nodig is vir die maak van die produk;
1.10 gepaste gereedskap en materiaal kies en gebruik om produkte deur middel van gepaste tegnieke te maak deur verskillende soorte materiaal akkuraat te meet, uit te merk, te knip/sny of te skei, te vorm of te vervorm, te heg, te las of saam te voeg, en af te rond;
1.12 die produk of stelsel evalueer gebaseer op kriteria wat direk met die ontwerpopdrag en sommige van die spesifikasies en beperkings verband hou, en verbeteringe of wysigings voorstel;
1.13 die doeltreffendheid van die plan van aksie wat gevolg is evalueer en voorstel hoe toekomstige planne verbeter kan word.

Absolutely, for me. My problems with math started in First grade...involving a nun Sister Anastasia, bad vision, talking & getting expelled from Catholic school. When it comes to math I just can't focus and all I can hear is our family silverware banging and clanging on the pink Formica table.

If f(x) = x-2 then, f(3) when 5f(x+1) 5((3-2)+1) 5(1+1) 5(2) 10

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul
hmm
Abhi
is it a question of log

why surface tension is zero at critical temperature
Shanjida
I think if critical temperature denote high temperature then a liquid stats boils that time the water stats to evaporate so some moles of h2o to up and due to high temp the bonding break they have low density so it can be a reason
