Content

Activity: to estimate, measure and record 2-dimensional shapes and 3-dimensional objects [lo 4.4.3]

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.

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
