- Scales are essential for estimating distances on maps when distance tables or markers are unavailable.
- It's usually possible to estimate distances with a scale, but not determine them accurately due to factors like precise measurement and specific destinations.
National Road Maps
- Show major routes, roads, and distances between major cities and towns in South Africa.
- Skills include deciding on routes, estimating costs and times, planning stops, and using distance tables.
Strip Charts
- Display locations of towns, roads, and points of interest on a specific route.
- Skills involve determining accurate distances, choosing stops for fuel or breaks, and estimating costs and times.
Street Maps
- Show positions and names of streets and locations within a city.
- Skills: identifying locations using symbols, following and giving directions, and using a grid reference system.
Housing Complex Maps
- Display positions of houses within a small complex.
- Skills involve working with maps of small areas and following directions to specific locations.
Calculation Type 1: Map Measurement to Actual Distance
- Measure a distance on the map, then use the scale to convert it to the actual distance.
- Formula: $\text{Actual distance} = \text{Map measurement} \times \text{Scale factor}$
Calculation Type 2: Actual Distance to Map Measurement
- Start with the actual distance, then use the scale to convert it to the map measurement.
- Formula: $\text{Map measurement} = \frac{\text{Actual distance}}{\text{Scale factor}}$
Number Scale
- Expressed as a ratio (e.g., 1:50,000) showing the relationship between the map and the actual area size.
- Conversion involves enlarging or reducing by the scale factor directly.
- A scale of 1:50,000 means the plan is 50,000 times smaller than the actual size.
Bar Scale
- Shows the relationship between measured length and actual distance on the map itself.
- Measuring on the bar scale indicates how many measured units equal actual distance.
- It remains accurate even if the map size changes because it resizes proportionally.
Floor Plan
- A 2D view of a building from above, without the roof, showing internal dimensions and layout including lengths and widths of the building, windows and doors.
Elevation Plan
- A 2D view of a building from the side, showing external dimensions and layout of the roof, walls, windows, and doors.
Design Drawing
- Shows the design, layout, and components of an item to be constructed or manufactured, it illustrates the different component parts, dimensions of these parts, and specific instructions on how they should look.
- Skills involve describing features, matching features between plans, understanding compass directions (North, South, East, West Elevation), and using scale to determine dimensions.
Plan Measure Calculation
- When converting from an actual dimension to a plan measure, reduce the actual measurement using the scale.
- Formula: $\text{Plan Measure} = \frac{\text{Actual Dimension}}{\text{Scale Factor}}$
- For example, if the actual height of a door is $2.1 \text{ m}$ and the scale is $1:75$: $\text{Plan Measure} = \frac{2.1 \text{ m}}{75} = 0.028 \text{ m} = 2.8 \text{ cm} = 28 \text{ mm}$
3D Models
- Grade 11 learners need to build 3D models from 2D plans and draw 2D plans/nets of 3D models.
- Use models to investigate packaging, perimeter, area, and volume problems.
Purpose of 2D to 3D shifting
- Facilitate the movement between 2D and 3D representations of objects.
- Involves moving from a 2D drawing to a 3D object and vice versa.
Process
- Understand 2D plans/nets which are flat layouts that form 3D objects when folded.
- Cut out the 2D net and fold along indicated lines.
- Assemble the folds to create the 3D model.
- Observe the 3D model and visualize how it unfolds into a flat layout to draw the net.
Assembling
- Carefully read and interpret instructions, identifying parts and components.
- Ensure all materials and tools are available in the correct size, quantity, and type.
- Measure accurately and cut materials as needed, estimating quantities, costs, and time.
- Follow steps in sequence, checking and adjusting as necessary, using mathematical tools and techniques.
