## Memorandum

1. Length of your desk = cm

Your own height = cm / m

Width of the class = m

Length of your pencil = cm / mm

2. km

## To use appropriate measuring instruments [lo 4.6.3]

From the work that was completed in Grades 4 and 5, you know that we always measure in units.

1. Take a good look at the following and then complete the table:

• Indicate which units you will use.
• Estimate the length.
• Then measure the true length.
 Unit Estimate Actual length Length of your desk ______________ ______________ ______________ Your own height ______________ ______________ ______________ Width of the class ______________ ______________ ______________ Thickness of your writing pad ______________ ______________ ______________ Length of your pencil ______________ ______________ ______________

2. In what unit would you measure the distance between your home and the school?

_____________________________________________________________________

3. Let us test your memory! See whether you are able to answer the following questions:

3.1 How many metres are there in 1 kilometre?____________________________

3.2 How many millimetres are there in 1 metre? ___________________________

3.3 How many centimetres are there in 1 metre? ___________________________

3.4 How many millimetres are there in 1 centimetre? _______________________

DO YOU REMEMBER THIS?

You should know it, but let us look at it again:

km m cm mm

## Assessment

Learning Outcome 4: The learner will be able to use appropriate measuring units, instruments and formulae in a variety of contexts.

Assessment Standard 4.5: We know this when the learner estimates, measures, records, compares and orders two-dimensional shapes and three-dimensional objects using S.I. units with appropriate precision for:

4.4.3: length using millimetres (mm), centimetres (cm), metres (m) and kilometres (km);

Assessment Standard 4.6: We know this when the learner re uses appropriate measuring instruments (with understanding of their limitations) to appropriate levels of precision including:

4.6.3: rulers, metre sticks, tape measures and trundle wheels to measure length.

College algebra is really hard?
Absolutely, for me. My problems with math started in First grade...involving a nun Sister Anastasia, bad vision, talking & getting expelled from Catholic school. When it comes to math I just can't focus and all I can hear is our family silverware banging and clanging on the pink Formica table.

I'm 13 and I understand it great

I am 1 year old but I can do it! 1+1=2 proof very hard for me though.
Atone
Not really they are just easy concepts which can be understood if you have great basics. I am 14 I understood them easily.

The given of f(x=x-2. then what is the value of this f(3) 5f(x+1)
hmm well what is the answer
Abhi
If f(x) = x-2 then, f(3) when 5f(x+1) 5((3-2)+1) 5(1+1) 5(2) 10

how do they get the third part x = (32)5/4
make 5/4 into a mixed number, make that a decimal, and then multiply 32 by the decimal 5/4 turns out to be

why surface tension is zero at critical temperature
Shanjida
I think if critical temperature denote high temperature then a liquid stats boils that time the water stats to evaporate so some moles of h2o to up and due to high temp the bonding break they have low density so it can be a reason
