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.

Activity: To use a range of techniques to perform calculations [LO 1.10.2]

Let us see how well you are able to apply your acquired knowledge of division. Calculate the following without using a pocket calculator. You may use whichever method you prefer.

BRAIN-TEASER!

During a competition, the Grade 5, 6 and 7’s tie. 21 cool drink cans are delivered to them at the school. Seven of the cans are completely full and 7 are half-full. Seven empty cans are also delivered.

How will you divide the cool drink among the three grades so that everyone gets the same amount of cool drink and cans? (Hint: make a sketch!)

TIME FOR SELF-ASSESSMENT

It is important for us to know how you feel about the section of the work that you have just completed. Evaluate yourself by placing a tick in the appropriate space:

 I can estimate the quotient by rounding off the divisor and the dividend. (LO 1.10) ____ ____ ____ ____ I can estimate the quotient by making use of doubling. (LO 1.10) ____ ____ ____ ____ I can estimate the quotient by making use of multiplication. (LO 1.10) ____ ____ ____ ____ I can predict the quotient by looking at certain patterns on my calculator. (LO 2.1) ____ ____ ____ ____ I can divide correctly and determine a remainder, without using my calculator. (LO 1.11) ____ ____ ____ ____

Assessment

Learning Outcome 1: The learner will be able to recognise, describe and represent numbers and their relationships, and to count, estimate, calculate and check with competence and confidence in solving problems.

Assessment Standard 1.10: We know this when the learner uses a range of techniques to perform written and mental calculations with whole numbers including:

1.10.2: long division.
