Foundations of Mathematics 20

#### Foundations of Mathematics 20 is divided into seven units. It meets the required outcomes outlined by Saskatchewan Learning, and is a prerequisite for Foundations of Mathematics 30. Students will require a TI-83 or TI-84 calculator in order to complete this course. This workbook series was developed for use by schools using an individualized, mastery-based learning system, and therefore comes with score keys, tests, and test keys. No additional text is necessary.

**Unit 1: Inductive and Deductive Reasoning**

At the end of unit one, the student should be able to:

- understand the difference between inductive and deductive reasoning
- form and analyze conjectures
- prove or disprove conjectures to solve problems
- solve problems using inductive and deductive reasoning
- analyze and strategize puzzles involving spatial reasoning

**Unit 2: Properties of Angles and Triangles**

At the end of unit two, the student should be able to:

- determine the measure of unknown angles using properties of angles formed by parallel lines and transversals
- determine the measure of unknown angles using angle properties of triangles
- determine the measure of unknown angles using angle properties of polygons
- derive proofs based on theorems and postulates about parallel lines and triangles
- solve problems that involve angles, parallel lines, transversals, and triangles

**Unit 3: Proportional Reasoning**

At the end of unit three, the student should be able to:

- solve problems that involve rates
- solve problems that involve scale factors
- determine the relationship between scale factors, surface areas, and volumes of similar objects
- use the relationship between scale factor, surface area, and volume in similar objects to solve problems
- solve real world problems using the properties of similar triangles

**Unit 4: Systems of Linear Inequalities**

At the end of unit four, the student should be able to:

- graph linear inequalities
- solve problems using linear inequalities in two variables
- solve problems using systems of inequalities in two variables
- graph the feasible region of a system of linear inequalities
- optimize a given objective quantity
- solve word problems by optimizing the objective quantity

**Unit 5: Quadratic Functions**

At the end of unit five, the student should be able to demonstrate an understanding of the characteristics of quadratic functions of the form y = a(x - p)2 + q, including:

- vertex
- intercepts
- domain and range
- axis of symmetry

**Unit 6: Trigonometry**

At the end of unit six, the student should be able to:

- completely solve a right triangle
- understand angle of elevation and angle of depression
- use the law of sines to solve triangles (determine side lengths and angle measures)
- use the law of cosines to solve triangles (determine side lengths and angle measures)
- solve problems by applying the law of sines and the law of cosines
- determine how many triangles are possible in the ambiguous case of an SSA triangle

**Unit 7: Statistical Reasoning**

At the end of unit seven, the student should be able to:

- analyze a numerical data set by creating a grouped frequency distribution table, a histogram, and a frequency polygon
- use a graphing calculator to analyze data as above
- calculate the mean, median, and the mode of a numerical data set
- calculate the range, mean deviation, and standard deviation of a numerical data set
- understand what it means for data to be normally distributed
- use a normal curve to estimate the number of data items lying within a specified range
- use a graphing calculator to draw normal curves
- convert actual data items to z-scores
- find the area under the standard normal curve
- find the probability of events whose outcomes are normally distributed
- use the area under the standard normal curve to estimate an actual data value
