## Memorandum

1. Lengte van jou bank = cm

Jou eie lengte = cm / m

Breedte van klas = m

Dikte van skryfblok = mm

Lengte van potlood = cm / mm

2. km

3.1 1 000

3.2 1 000

3.3 100

3.4 10

## Om gebruik te maak van toepaslike meetinstrumente [LU 4.6.3]

Jy weet nou al uit die werk wat ons in graad 4 en 5 afgehandel het dat ons altyd in eenhede meet.

1. Kyk goed na die volgende en voltooi dan die tabel:

• Sê in watter eenheid sal jy die volgende meet.
• Skat die lengte.
• Meet dan die ware lengte.
 Eenheid Skatting Werklike lengte Lengte van jou bank ______________ ______________ ______________ Jou eie lengte ______________ ______________ ______________ Breedte van klas ______________ ______________ ______________ Dikte van skryfblok ______________ ______________ ______________ Lengte van potlood ______________ ______________ ______________

2. In watter eenheid sal jy die afstand tussen jou huis en die skool meet?

_____________________________________________________________________

3. Kom ons toets jou geheue! Kyk of jy die volgende vrae kan beantwoord:

3.1 Hoeveel meter is daar in 1 kilometer?____________________________

3.2 Hoeveel millimeter is daar in 1 meter? ___________________________

3.3 Hoeveel sentimeter is daar in 1 meter?___________________________

3.4 Hoeveel millimeter is daar in 1 sentimeter?_______________________

ONTHOU JY NOG?

Die volgende behoort jy reeds te ken, maar kom ons kyk weer daarna:

km m cm mm

## Assessering

Leeruitkomste 4:Die leerder is in staat om gepaste meeteenhede, instrumente en formules in ‘n verskeidenheid kontekste te gebruik.

Assesseringstandaard 4.4: Dit is duidelik wanneer die leerder twee-dimensionele en drie-dimensionele voorwerpe skat, meet, aantekeninge maak van, vergelyk en orden deur S.I.-eenhede met die geskikte noukeurigheid te gebruik vir:

4.4.3: lengte m.b.v. millimeter (mm), sentimeter (cm), meter (m) en kilometer (km);

Assesseringstandaard 4.6: Dit is duidelik wanneer die leerder gepaste meetinstrumente gebruik (met ‘n begrip vir die beperkings daarvan) tot op geskikte vlakke van noukeurigheid, insluitend:

4.6.3: liniale, meterstokke, maatbande en klikwiele om lengte te meet.
