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.

ACTIVITY: To recognise and represent numbers in order to describe and compare them [LO 1.3.4]

To determine output values for given input values [LO 2.3.2]

1. Do you remember the following? In Grade 5 (Module 2) we looked at the rules for multiplying and dividing by 0 and 1. Let us look at the properties of 0 and 1:

Fill in any number on the left and complete the flow diagram.

Figure 1 (graphics1.jpg)
1.1

Figure 2
Figure 2 (graphics2.jpg)
1.2

1.3

Figure 3
Figure 3 (graphics3.png)

2. Tell a friend which calculations with 0 do NOT change the value of a number.

NOTE!

Dividing with 0 is not allowed. We say that dividing by 0 is undefined.

3. Once again, fill in numbers on the left and complete the flow diagrams:

3.3

3.4

4. Tell a friend which calculations with 1 do NOT change the value of a number.

5. Now calculate:

5.1 148 x 0 x 236 =

5.2 0 ¸ 36 =

5.3 34 ¸ 1 x 1 =

5.4 k + 0 =

5.5 c ¸ 0 =

  • 58 ¸ 0 =

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 1.3: We know this when the learner recognises and represents the following numbers in order to describe and compare them:

1.3.4: 0 in terms of its additive property.
