divide class into groups and hand out objects of which the volume will be calculated in the internalization phase.
divide into groups of 4 and receive the objects.
Internalization
Teacher instructs the learners to calculate the volume of each object handed out (See annexure D) (group work)
The teacher will walk through the class assisting and guiding the learners to do calculations correctly. Helping them to get to the right answers.
The learners will calculate the volume of the objects in groups of four. Must help each other to do the calculations.
Learners will listen, ask questions (where needed) and complete the activity in the time provided.

The teacher will ask learners to give feedback once activity is finished. (Whole class discussion)
The learners will provide the teacher with their answers (if it is required of them) and write down the correct answers provided by the teacher (if they had an incorrect answer)
Asses answers learners give for exercise
Application
Review content (See annexure F)
Teacher will instruct learners to complete activity. Teacher will instruct them to start with the activity and complete it for homework (See annexure E)
The learners will answer the teacher’s questions (when it is required of them).

Reflection I enjoyed preparing this lesson, as I know the content very well. I’ve been teaching this class
from the beginning of the year, thus feel comfortable teaching them.
Did the learners achieve the outcomes?
What could I have done better?
How can I improve for next time?

Begin met voorbeelde
Leeruitkomstes vir die les:
a) Definieer die konsep Volume
b) Definieer die konsep driedemensioneel
c) Bereken die volume van ‘n reghoekige voorwerp
d) Bereken die volume van ‘n silinder
e) Gee die korrekte formule vir elke vorm
f) Differensieer tussen lengte, breedte en hoogte
Toets vorige kennis:
In die vorige les het ons die Area/Opp bereken van ‘n reghoek, sirkel en driehoek.
Definisie van AREA:
Area is ‘n twee-dimensionele konsep. Die area van ‘n vorm is die hoeveelheid ruimte
wat die vorm beslaan/opneem.
Byvoorbeel: Die area wat ‘n stuk hout op die vloer opneem is die grootte van die vloer
spasie wat dit oopneem.
Ons werk met twee-dimensies wanneer on area bereken – lengte en breedte.
Area word altyd gemeet in eenhede² - byvoorbeeld mm², cm², m² .
FORMULES VIR DIE BEREKENING VAN OPPERVLAKTE/AREA:
Area van ‘n reghoek = lengte x breedte
Area van ‘n sirkel = π × r²
Area van ‘n driehoek = ½ × basis × hoogte van driehoekh

Annexure C:
Nuwe Konsepte Definisies:
Volume
Volume is ‘n driedimensionele kosep. Die volume van ‘n voorwerp is die grootte van die
driedimensionele spasie wat ‘n voorwerp opneem of kan behou.
Solide voorwerp?
Die hoeveelheid 3D ruimte wat ‘n voorwerp opneem/beslaan.
Baksteen
Hol voorwerp?
Die kapasiteit (inhoudsmaat) wat die voorverp kan behou.
Glas met water
Wanneer met volume werk, werk mens met 3 dimensies – lengte, breedte en hoogte.
Volume word altyd gemeet in eenhedeᵌ - bv. mmᵌ, cmᵌ, mᵌ.
1) Die volume van ‘n reghoekige voorwerp = (area van reghoek) × hoogte
= (lengte × breedte) × hoogte
= l × b × h
2) Die volume van ‘n silinder = (area van sirkel) × hoogte
= (π × r²) × hoogte
= πr² × h
Annexure D
Verdeel in 4 groepe. Elke groep kry 2 reghoekige voorwerpe en 2 silinders. Ons sal dan
die volume bereken van elke voorwerp. Neem mates van gegewe voorwerpe.
Die volume van ‘n reghoekige voorwerp = lengte × breedte × hoogte

(Group activity – MEMO)
Verdeel in 4 groepe. Elke groep kry 2 reghoekige voorwerpe en 2 silinders. Ons sal dan
die volume bereken van elke voorwerp. Vra leerders om die mates te neem van elke
voorwerp – doen voorbeelde saam met hul op die bord.
Die volume van ‘n reghoekige voorwerp = lengte × breedte × hoogte
(Bereken antwoord in mm)
= l × b × h
= 90mm × 30mm ×15mm
= 40 500mm3
= l × b × h
= 60mm × 29mm ×29mm
= 50 460mm3
Die volume van silinder = πr² × hoogte NB!! Π = 3,14
= πr² × h
= 3,14(13,5)² × 60mm = 34 335,9
≈ 34 336mm3
