**Introduction to Construction Math**Module 00102-04**Transparency 1**Objectives Upon completion of this module, you will be able to do the following: 1. Add, subtract, multiply, and divide whole numbers, with and without and without a calculator. 2. Use a standard ruler and a metric ruler to measure. 3. Add, subtract, multiply, and divide fractions. 4. Add, subtract, multiply, and divide decimals, with and without a calculator. 5. Convert decimals to percentages and percentages to decimals. 6. Convert fractions to decimals and decimals to fractions. 7. Explain what the metric system is and how it is important in the construction trade. 8. Recognize and use metric units of length, weight, volume, and temperature. 9. Recognize some of the basic shapes used in the construction industry, and apply basic geometry to measure them.**Transparency 2**Figure 3 - Counting out the wrenches**Transparency 3**Figure 6 - Types of measurement tools**Transparency 4**Figure 8 - The architect’s scale**Transparency 5**Figure 10 - Identify the measurement**Transparency 6**Figure 14 - Showing 1.3 inches on a machinist’s rule**Transparency 7**Figure 19 - 100-Gallon-capacity tank**Transparency 8**Figure 20 - What type of measurement is it?**Transparency 9**Figure 22 - Metric ruler**Transparency 10**Figure 29 - Typical angles**Transparency 11**Figure 30 - Common shapes**Transparency 12**Figure 32 - Cutting a rectangle on the diagonal produces two right triangles**Transparency 13**Figure 33 - Cutting a square on the diagonal produces two right triangles**Transparency 14**Figure 34 - The sum of a triangle’s three angles always equals 180 degrees**Transparency 15**Figure S-2 - Types of triangles**Transparency 16**Figure 35 - Measurements that apply to circles**Transparency 17**Figure 36 - Volume of a rectangle**Transparency 18**Figure 37 - Volume of a cube**Transparency 19**Figure 38 - Volume of a cylinder**Figure 31 - What common shapes can you find at this**construction site?
