Content

In this module we are going to measure with the aid of various instruments.

We are going to measure:

  • length,
  • mass,
  • circumference,
  • area,
  • volume,
  • content,
  • temperature and
  • time.

Activity: to measure and calculate a perimeter [lo 4.4.3, lo 4.8.1]

1. An ant must walk from A to B, then to C, D, E and again to A (right around – perimeter).

1.1 What instrument will you use to calculate how far the ant walks?

1.2 Now calculate the distance the ant has walked.

1.3 In what unit did you measure? _____________________________________

1.4 What unit did your friend use? _____________________________________

2. Take a look at the following figures. Are you able to tell the educator what the "ordinary" name for each one (excepting the square) is?

square

2.1 These shapes are regular. Why?

2.2 Calculate the perimeter of each shape (remember the units). Write the name of each shape, followed by the answer.

(a) __________________________________________________________________

(b) _________________________________________________________________

(c) __________________________________________________________________

(d) _________________________________________________________________

2.3 If the perimeter of a square can be calculated by means of the formula 4 x side, which formula would be used for each of these shapes? Write the name of the shape, followed by the answer.

(a) __________________________________________________________________

(b) _________________________________________________________________

(c) __________________________________________________________________

(d) _________________________________________________________________

2.4 What do we call the following shape?

_____________________________________________________________________

2.5 Can you perhaps deduce a formula for calculating the perimeter of a rectangle?

_____________________________________________________________________

REMEMBER THIS!

A square also happens to be a rectangle. It just happens to be one with four equal sides. All squares are rectangles, but all rectangles are not square.

3. Here are a few irregular shapes.

3.1 Why do we say that these shapes are irregular?

_____________________________________________________________________

3.2 Now calculate the perimeter of each of the irregular shapes.

A: __________________________________________________________________

B: __________________________________________________________________

C: __________________________________________________________________

Assessment

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

Assessment Standard 4.4: 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 4.8: We know this when the learner investigates and approximates (alone and/or as a member of a group or team):

4.8.1: perimeter using rulers or measuring tapes.
