## Numeric patterns

Activity 1:

 To recognise and represent multiples in order to be able to describe, compare and represent them [LO 1.3] To investigate numeric patterns [LO 2.1] To describe numeric patterns in your own words [LO 2.2] To find output numbers [LO 2.3]

1. When we count in 6’s we are saying the multiples of 6.

1.1 Work with a friend. One of you must count in 6’s from 0 to 102. The other one must use a calculator to check you and stop you if you make a mistake. If that happens the one with the calculator must just say, ”Stop!” and show the calculator. The counting goes on from there. Then swap over.

1.2 Now fill in the missing multiples of 6 in the table below:

 1 2 3 4 5 6 7 8 9 10 11 12 × 6 6 12 18 24 30 60 66

1.3 Now count backwards in 6’s from 102 to 0. Let a friend check you. Then swap over. Do you notice anything? Yes, multiples of 6 are all even numbers.

1.4 What patterns do you notice? Yes, the last digits seem to be 6;..2; ..8; ..4; ..0. They are repeated and so form a pattern.

Now that you are aware of this, you can count in 6’s for ever (if you concentrate)!

1.5 Count in 6’s and complete the flow diagram:

1.6 How do we programme the calculator to count in 6’s?

Press clear and

1.7 Write down the multiples of 6 from 102 to 0:

1.8 How do we programme the calculator to count backwards in 6’s from 102?

Press clear and

Now you can really count in 6’s easily, so let’s move on to 7’s.

2. Multiples of 7

2.1 Now use your calculator (if necessary) to count in 7’s and complete the flow diagram:

Can you spot any patterns? Two are written below. Try to spot some more and discuss with a friend.

• They are both odd and even numbers.
• They seem to be: odd, even, odd, even.

2.2 Now fill in the missing multiples of 7:

 1 2 3 4 5 6 7 8 9 10 11 12 × 7 7 14 21 70 77

There seems to be some sort of repetition after the first 9 multiples. Does it continue?

Are there any other patterns? Write down what you have noticed.

• Count backwards in 7’s from 105 to 0. Use your calculator to do this if necessary.
• Write the missing multiples of 6 in the table below and then the multiples of 7 in the next row. Do you notice anything?
 1 2 3 4 5 6 7 8 9 10 11 12 × 6 6 12 18 24 × 7 7 14 21 28

2.5 Now compare the two rows (across) of answers. A very interesting pattern appears to be emerging.

Look: 1 × 7 = 1× 6 + 1

5 × 7 = 5 × 6 + ……

9 × 7 = 9 × 6 + ……

2 × 7 = 2 × 6 + …….

6 × 7 = 6 × 6 + ……

10 × 7 = 10 × 6 + …..

1. × 7 = 3 × 6 + ……
2. 7 × 7 = 7 × 6 + ……
3. 11 × 7 = 11 × 6 +……

4 × 7 = 4 × 6 + ……

8 × 7 = 8 × 6 + ……

12 × 7 = 12 × 6 +……

3. Multiples of 8

3.1 The numbers jump in 8 wholes. Use the calculator to count in 8’s and write down the missing multiples of 8.

0, 8, 16, 24, 32,……., ……., …………, ………, ………….,…………,………., …………, ……., …….., …………, ……… .

3.2 Another way of saying: 8 + 8 + 8 + 8 is 4 × 8.

Now complete the flow diagram:

3.3 Spot a pattern. Write down the missing multiples of 8 in the table below and look at the last digit of each one.

 1 2 3 4 5 6 7 8 9 10 11 12 × 8 8 16 80 88

Look carefully:

8 ; 1 6 ; 2 4 ; 3 2 ; 4 0 ; 48; 56; 64; 72; 80; 88; 96

where we get a research paper on Nano chemistry....?
nanopartical of organic/inorganic / physical chemistry , pdf / thesis / review
Ali
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level

no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts

I only see partial conversation and what's the question here!
what about nanotechnology for water purification
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.

what is the stm
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

Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION

what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale

Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
