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.
