Preparation Guide for

Moving Straight Ahead Unit Test

Essential Learnings - students should know how to:

• Translate information about linear relationships given a table, a graph, or an equation to one of the other forms.

• Solve problems and make decisions about linear relationships using information given in tables, graphs, and equations.

Additionally students should be able to:

• Construct tables, graphs and symbolic equations.
• Recognize linear relationships
• Solve an equation for an unknown.
• Find x or y when you substitute in the other value in an equation.
• Find the slope of a line given two points on a line or given an equation.
• Find point of intersection of two lines given a graph, a table or two equations.
• Find y-intercept when given an equation.
• Be able to use and understand the vocabulary terms we have learned in class such as linear relationship, point of intersection, y-intercept, slope, coefficient, rise, run, horizontal, vertical, coordinate pair, etc.

Focus questions/ problems - students should study by reviewing & redoing the following:

• The packet with 20 practice problems solving for x.
• These specific sections from the Moving Straight Ahead book; Problem 1.2, Problem 1.3, Problem 3.4, Problem 3.5 & Problem 4.2.

Investigation 3 - Solving Equations

In this Investigation the students are looking at working with and solving linear equations.

Essential Questions:
1. How are the coordinates of a point on a line or table related to the equation of a line?
2. What does equality mean?
3. How can the properties of equality be used to solve linear equations?

Here are the notes from Inv 3.2 showing the exploration of equalities.  In the notes we show two methods to solve for an unknown variable (visual and mathematical).

New Unit - Moving Straight Ahead

The primary goal of this Unit is for students to develop an understanding of linear relationships. Students recognize linear relationships by the constant rate of change between two variables in a contextual situation, a table, a graph, or an equation.

New Unit Comparing and Scaling

Welcome to our new unit focusing on ratios, rates, percents and proportions.

Investigation 1: Ways of Comparing: Ratios and Proportions

Investigation 1 focuses on different strategies for comparing quantities—using ratios, fractions, percents. Students learn what different types of comparative statements say about data given. They are asked to write comparative statements using ratios and differences that describe data. 

We have completed Investigation 1.1 -1.2 in the new Comparing and Scaling Book.
We focused on the ability to make comparisons of quantitative data. 
We focused on making comparisons through:
1. ratios
2. differences
3. percents
4. simplified ratios

Further we stressed the importance of making comparisons between part-to-part or part-to-whole.
