MATHEMATICAL LITERACY GRADE 11 CAPS TOPIC 4 Maps

MATHEMATICAL LITERACY GRADE 11 CAPS TOPIC 4: Maps, plans and other representations of the physical world Section 4. 4: Plans (floor, elevation and design plans)

Topic 4: Maps, plans and other representations of the physical world The following sections will be covered: 4. 1. Scale 4. 2. Maps 4. 3. Models 4. 4. Plans (floor, elevation and design plans)

Plans In Section 4. 4, learners will be able to: Work with rough and scaled elevation plans (front, back and side) showing a side view perspective. Understand the terms ‘North’, ‘South’, ‘East’, and ‘West’, elevations in the construction of buildings. Connect the features on elevation plans with features and perspectives shown on the floor plan of the same structure. Plans are drawn to scale in building houses. On plans of buildings, North will always be indicated. Floor, elevation and design plans tell us how to build houses. Final Assessment Questions

Example 1: Consider the following drawing of one room garden shed:

Example 1 a) Draw a rough front elevation plan of the garden shed. b) Draw a rough side elevation plan of the garden shed. c) Draw the rough top elevation of the garden shed. d) Determine a suitable scale of the garden shed. e) Draw the scaled front elevation plan accurately according to the determined plan measurements.

Solution: Example 1 a) Rough front elevation plan:

Elevation Plans Elevation plans are also named after the geographic directions from which they are being looked at. The compass points are drawn with the north point shown pointing to the top as shown below:

Elevation Plans The elevation plan of the structure facing north is ‘North elevation’, the one facing south, ‘South elevation’, the one facing east, ‘East elevation’ and the one facing west ‘West elevation’. Find the elevations of the figure below:

Elevation Plans The elevations of the building in the previous slide are shown below:

Final Assessment Questions Question 1 Use figure 3 below to answer the following questions:

Question 1 (a) Draw (not to scale) each of its North, South, East and West elevations. (b) Given that 1 m = 3, 281 feet (ft), convert 6 ft and 8 ft into metres (m). (c) Now choose a suitable scale and then draw the South Elevation of the house to scale. The door can remain being a rough drawing (not to scale)
