Key Concepts• The modeling process vs. UPIC• Ordered Pairs• Function Notation• Additive process• Inequality Notation• Simulation• Scale Change Transformation

LESSON 1OVERVIEW

Lesson 1 continues the use of recursive equations and closed-form equations. Students also use their prior knowledge of ordered pairs and are introduced to function notation. The pencil problem gives a simple, real-life application for students to use.

LESSON 1• The mathematical

modeling process is introduced to students.

• Identify a situation.

• Simplify the situation.

• Build a model• Evaluate and

revise the model

LESSON 2OVERVIEW

• With lesson 2 students are asked to simulate a real-life situation.

• Students are divided into groups and given a role.

• Students use the mathematical modeling process.

LESSON 2• Students use a data sheet of

information about moose.• Students use computer based

spreadsheet.• Students write linear equations.

TECHNOLOGY• Lesson 1 and 2 allows for the

integration of technology in the classroom.

• For Lesson 1 students use graphing calculators.

• For Lesson 2 students use Excel.

PRIOR KNOWLEDGE VOCABULARY

• Students must retain prior knowledge from previous chapters.

• Recursive equations and closed-form equations continue into Chapter 6.

RECURSIVE EQUATIONS• Indicate the relationship between

the current value of a variable based on the previous value of the same variable using a constant increment in the explanatory variable. Recursive equations require designation of an initial condition.

CLOSED FORM EQUATIONS

• Equations that allow you to find the value of one variable given the value of the other variable.

• X = -3 + 5t

Mathematical Modeling• The process of

beginning with a situation and gaining understanding about that situation through the use of mathematics.

Ordered Pair• Two numbers

designating the values of two quantities, where the order in which the numbers appear indicates their meaning.

FUNCTION NOTATION

• C(1) = 25

• The value of c is 25 when the other quantity is 1

• A way to show the value of one quantity whose value is determined by the value of another quantity.

ADDITIVE PROCESS• Any process described by a

recursive equation of the form Q(n + 1) = Q(n) + k where k is a constant.

INEQUALITY NOTATION• A mathematical statement of the

relationship between two numbers that are not necessarily equal.

• Examples: 1 < 4 or 0 < x < 2

SIMULATION• Acting out the

details of a situation you are modeling. May use equations, graphs, technology, physical objects.

SCALE CHANGE TRANSFORMATION

• A transformation in which all first coordinates (or second) are multiplied by the same constant, resulting in a horizontal (or vertical) stretch of the corresponding graph.
