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?

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.

Inhoud

Om strategieë te gebruik om oplossings te kontroleer [LU 1.11]

In aktiwiteit 2.7 het jul seker gesien dat daar verskeie maniere is om die kwosiënt te bereken. Werk nou saam met ‘n maat deur die verskillende oplossings vir die volgende probleem:

Hoeveel mense het altesaam soveel tande soos een dinosourus?

1. Ek moet 2 400 deur 28 deel.

Ek skat so 50 keer.

Ek weet 28 × 100 = 2 800

Dus: 28 × 50 = 1 400

En 28 × 25 = 700

Die antwoord is dus 50 + 25 + 10 = 85 mense. Daar is 20 tande wat oorbly.

2. Ek moet 2 400 ÷ 28 bereken:

Daar is dus 85 mense, want daar is 8 tande te min vir nog ’n persoon.

3. Kan julle die probleem op enige ander manier oplos? (Sonder ’n sakrekenaar.)
