Summary notes

Brick and Glass as example

10 min

Exposition

Give full definition of each concept (see annexure C)

The teacher will test for understanding of each concept by doing an example of each with the class.

Teacher will divide class into groups and hand out objects of which the volume will be calculated in the internalization phase.

.

Learners will listen when new concepts are explained.

Learners will underline/ highlight on their summary sheets.

Learners answer questions asked and take part in interaction with the teacher

Learners will divide into groups of 4 and receive the objects.

10min

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 teacher will ask learners to give feedback once activity is finished. (Whole class discussion)

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 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)

Observation, Question and answering

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 teachers questions (when it is required of them).

The learners will write down there homework and start it in class (if there is still time available) and finish it for homework.

Question and answering

Assess whether learners understand homework

Reflection

I enjoyed preparing this lesson, as I know the content very well. Ive 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 eenhede - byvoorbeeld mm, cm, m .

FORMULES VIR DIE BEREKENING VAN OPPERVLAKTE/AREA:

(b)

Area van n reghoek = lengte x breedte

(l)

(r)

Area van n sirkel = r

(b) (h)Area van n driehoek = basis hoogte van driehoek

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 eenhede - bv. mm, cm, m.

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

= ( r) hoogte

= r 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.

(1.)Die volume van n reghoekige voorwerp = lengte breedte hoogte (Bereken antwoord in mm)

(15mm) = l b h

(30mm) = 90mm 30mm 15mm

(90mm ) = 40 500

(2.)

(29mm)= l b h

= 60mm 29mm 29mm

(29mm) = 50 460

(60mm )

Die volume van silinder = r hoogteNB!! = 3,14

(4.)

Bereken antwoord in cm.

(h 3,5cm) = r h

= 3,14(4.25) 3,5

= 198,5068

( 8,5cm ) (Radius = 4,25cm) 199
