THE TEXTBOOK
The curriculum and NOT the ‘textbook’ represents the learning content.
The textbook is only the source to be used to work through the curriculum.
UNFORTUNATELY all textbooks are not equally complete and also a textbook’s facts (especially terminology) is not necessary always correct.
E.g. FOCUS’s definition of a settlement in the “glossary” is quite incomplete: ....” A settlement is a place where a group of people live” (page 172 / 336). Look at the photo:
I also see a building (buildings), farming (activities) and the farmstead is connected by road with the wine yards/cultivated lands/pasture/outside buildings etc. However, FOCUS described it as such in the text on page 172.
Then, each part of the settlement does not function on its own, it is interconnected ..... as in a system.
FOCUS p. 180: ‘Economic factors’: Rural settlements are covered, but the third point, referring to Skukuza, is NOT correct – Skukuza is not a rural settlement!
More inaccuracy occurs in the Afrikaans “VERKEN”.
WHAT IS THE SOLUTION?
It is strongly recommended that teachers/facilitators/tutors at centres make use of more than one textbook, AND proper preparation.

MAPWORK TECHNIQUES: A SUMMARY THE INDEX OF THE MAP SHEET (MAP SHEET REFERENCE)
E.g. 3322CA • Refers to the co-ordinates of the north- western corner of the topographic map sheet. 33: Line of Latitude (° South) 22: Line of Longitude (° East) SCALE
• Representative fraction 1:50 000 (1cm represents 50 000 cm, divide denominator by 100 000 to get km).
CALCULATE DISTANCE
Map distance … cm [to 1 decimal]
Word scale x …. km ( or x … m) Real distance = …. km (= ….. m)
CALCULATE AREA
Formula: Area = Length x Breadth = …. km x ….km = ……………. km²
• Word scale 1cm represents 0,5km • Line scale 0 1. 5
km METHOD TO DETERMINE TRUE BEARING
1. Join the given points on the map with a line. 2. Draw a True North line from the point of measurement. 3. Place protractor with 0° on True North line. 4. Read clockwise from True North line. 5. TRUE BEARING is the degrees measured. Measure True Bearing always in full degrees.

Magnetic declination is the angle with which the Magnetic North deviates from True North. The angle changes continuously. In the example the .3 must be converted
to minutes: 3 x 6' = 18' and magnetic declination reads 22° 18' West of True North.

= For every 75 metres horizontal distance, the landscape rises or falls 1 metre.
CROSS-SECTIONS
Sketch views:
These are simple profiles (side views) of the landscape drawn free-hand, not accurate according to vertical and horizontal scale, showing the basic characteristics. E.g. River
Slip-off slope Undercut slope
Accurate cross-sections
1. Join the given points on the map with a line. 2. On a piece of paper, mark off all the points where the contours cross this line. Be as accurate as possible. 3. Determine the height of every contour line. 4. Draw a graph – vertical & horizontal axis (usually given). 5. Fill in the vertical scale as per instruction (e.g. 1cm represents 20m / 40m). 6. Transfer the position of the contour lines to the horizontal axis. 7. Mark the contour heights on the graph. 8. Join these heights, free-hand, taking into account that crests of hills and valley floors show curves and not straight lines.
EXAGGERATION OF THE VERTICAL SCALE
• Refers to how much the vertical scale is ‘stretched’ in relation to the horizontal scale. • Why is it necessary to make the vertical scale larger? E.g. Horizontal scale: 1:50 000 Vertical scale: 1cm represents 20m = 1:2 000 1 Formula:

CALCULATE THE SCALE OF A VERTICAL AERIAL PHOTOGRAPH (ORTHOPHOTO MAP)
Most popular formula: Photo scale = 1: Map scale denominator x Map distance (cm) Photo distance (cm) E.g. = 1: 50 000 x 3 (cm) 5 (cm) = 1:30 000

The numerator must be one (1), so divide the numerator and denominator by 20.
MAKE SUMMARIES The learners should not sit passively looking for the textbook and think they are learning the facts. They have to do actively summaries of every day’s small piece of work. Note: Summaries are NOT equal to ‘rewrite the textbook’. However, terminology (definitions) should be written factually. The following two examples serve as a guideline.
MID-LATITUDE CYCLONE [+ other names]
Temperate cyclone / Frontal depression Extra tropical cyclone
TROPICAL CYCLONE [+ other names]
(and specify the areas, e.g. Gulf of Mexico)
Isobars
Formation
Where on earth? (Specify the areas)
Names
No name are given to these systems
Human names, alphabetically ....
Fronts
Cold and warm fronts. Why? No fronts. Why?
Direction of movement
(Specify)
Cross-sections E.g.: Mature stage / Only through cold front / Only through warm front / Occlussion fronts (cold / warm)
Mature stage (complete) Only through the ‘eye’ area
