##### Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

##### What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

##### Who can create a lens?

Any individual member, a community, or a respected organization.

##### What are tags?

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

## Memorandum

1.1 50 000 + 400 + 30 + 6

1.2 90 000 + 800 + 10 + 7

### KOPKRAPPER!

100 000

100 000; honderd duisend

## Inhoud

### AKTIWITEIT: Om ‘n reeks tegnieke te gebruik om berekeninge te doen [1.10.3]

1. Kan jy nog onthou wat “uitgebreide notasie” beteken? Verduidelik gou vir ‘n maat. Kyk dan na die voorbeeld en kyk of jy die volgende getalle in uitgebreide notasie kan skryf.

bv. 36 518 = 30 000 + 6 000 + 500 + 10 + 8

1.1 50 436 =

1.2 98 017 =

### KOPKRAPPERS!

Watter getal is 10 keer groter as 10 000?

Kan jy die ontbrekende antwoorde invul?

9 + 1 = 10 tien

99 + 1 = 100 eenhonderd

999 + 1 = 1 000 eenduisend

9 999 + 1 = 10 tienduisend

99 999 + 1 = __________________ __________________

• Kom ons kyk of jy korrek was!
 Honderdduisend Tienduisend Duisend Honderd Tien Een HD TD D H T E 10 × 10 × 10 × 10 × 10 10 × 10 × 10 × 10 10 × 10 × 10 10 × 10 10 1 3 1 8 5 2 6

Ons lees 318 526: driehonderd en agtienduisend vyfhonderd ses en twintig

Jy was dus reg as jy 100 000 (honderdduisend) gesê het!

## Assessering

Leeruitkomste 1:Die leerder is in staat om getalle en hul verwantskappe te herken, te beskryf en voor te stel. Hulle kan ook met bekwaamheid en vertroue tel, skat, bereken en kontroleer tydens die oplos van probleme.

Assesseringstandaard 1.10: Dit is duidelik wanneer die leerder ‘n verskeidenheid tegnieke gebruik om sowel skriftelike as hoofberekeninge met heelgetalle te doen, insluitend:

1.10.3: opbou en afbreek van getalle.

## Content actions
