### Lenses

What is a lens?

#### Definition of a lens

##### 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.

## Content

### ACTIVITY: To solve problems in context [LO 1.6.2]

1. Your educator will provide the required paper. Examine the diagram below and copy it exactly. Try to construct your own cube from this.

• You now have a container with the following measurements:

1 cm by 1 cm by 1 cm

• We therefore say that the volume of the container is:

1 cm × 1 cm × 1 cm = 1 cm3

(one cubic centimetre)

volume = length × width × height

2. How many of these boxes (of 1 cm3) will you need to build a cube of 8 cm3? (2 cm × 2 cm × 2 cm)

2.1 8 cm3 = (2 cm × 2 cm × 2 cm): ___________________ cubes

2.2 27 cm3 = (3 cm × 3 cm × 3 cm): __________________ cubes

2.3 64 cm3 = (4 cm × 4 cm × 4 cm): __________________ cubes

2.4 125 cm3 = (5 cm × 5 cm × 5 cm): _________________ cubes

## Assessment

Learning Outcome 4:The learner will be able to use appropriate measuring units, instruments and formulae in a variety of contexts.

Assessment Standard 4.8: We know this when the learner investigates and approximates (alone and/or as a member of a group or team):

4.8.3: volume/capacity of objects (by packing or filling them) in order to develop rules for calculating volume of rectangular prisms.
