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.

1.1

1.2

1.3

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:

3.1

3.2

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.

what are the products of Nano chemistry?
Maira Reply
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think

Nasa has use it in the 60's, copper as water purification in the moon travel.

is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
