Activity: to perform mental calculations [lo 1.9.1, lo 1.9.2]

1. In Mathematics it is important to be able to think fast. Let’s see how quick you are in your first mental arithmetic test in Grade 6. Work as quickly and as accurately as possible.

1. think fast!

In Mathematics it is important to be able to think fast. Let’s see how quick you are in your first mental arithmetic test in Grade 6. Work as quickly and as accurately as possible.

1.1 56 + ................. = 83 1.4 .................  9 = 7
1.2 49 × 15 = ................. 1.5 Halve 85: .................
1.3 12 × 8 = ................. 1.6 Double 163: .................
1.7 20 × ................. = 2 000 1.12 A half × ................. = 150
1.8 (7 × 9) − 8 ................. 1.13.. (38 + 49) − 24 = .................
1.9 98 + 99 + 97 = ................. 1.14 89 ................. 16 = 105
1.10 1 004 − 12 = ................. 1.15 998 − ................. = 550
1.11 8 × 9 × 6 = 6 × ............ × 9

Complete: I have _____________________________________ correct!!

Did you know?

Can you remember what numbering system we make use of today?

____________________________________________________________________

The ancient Romans developed their counting system more than 2 000 years ago and some of their numbers looked like this: I ; II ; III ; IV ; V

2. let’s count

Work with a friend and take turns to count in:

2.1 tens from 19 870 to 20 040

2.2 hundreds from 67 403 backwards to 65 903

  • thousands from 37 556 backwards to 29 556
  • ten thousands from 25 526 to 95 526

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 1.9: We know this when the learner performs mental calculations involving:

1.9.1: addition and subtraction;

1.9.2: multiplication of whole numbers to at least 12 x 12.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
