Teacher's Guide Module 1 - Maths Excellence

4. MEASUREMENT AND TIME (LO 1, 2, 4 AND 5
LEARNING UNIT 1 FOCUSES ON LENGTH.
Emphasise the use of correct abbreviations. Also spend adequate time on explaining
how to convert correctly from one unit to another, as learners usually find this quite
complicated. Be convinced that the learners understand the different formulas for
calculating perimeter and are able to apply them correctly so that they will not be
confused when they start to work with area. Also pay attention to the calculation of
averages as this has not been dealt with before.
LEARNING UNIT 2 FOCUSES ON AREA.
Ensure that the learners understand the difference between area and perimeter. Also
ensure that they know the correct formulas and are able to apply them. The calculation
of area of irregular figures is also dealt with. Allow extra time for this, if necessary, so
that learners will be able to do the calculations.
LEARNING UNIT 3 FOCUSES ON MASS.
Learners must be able to read measuring scales / a balance. The emphasis, however,
is on the correct application of the 4 main operations in calculating mass.
LEARNING UNIT 4 FOCUSES ON CAPACITY.
Here learners should be able to do the conversions correctly. They should also be able
to read capacity correctly from a measuring cup. As in the previous learning unit, the
emphasis is on accurately solving problems in context.
LEARNING UNIT 5 FOCUSES ON VOLUME.
It is important for the learners to know the formula and to apply it correctly.
LEARNING UNIT 6 FOCUSES ON TIME.
Ensure that the learners learn the correct abbreviations.
Also point out the correct way of writing time as shown on a digital clock (international
time). Learners must be taught to add and subtract time correctly. Adequate attention
should therefore be given to correct conversion of units of time.
