Month: August Moving Straight Ahead
1. Big Ideas
Student answers to EQs that
lead them to the Big Ideas
A relationship is linear if there is a constant rate of change between variables. The pattern of change in a linear
relationship will show up in a table through observing a constant increase or decrease in the dependent variable as the
independent variable increases by a constant amount. In a graph, the linear pattern of change shows up as a straight
line. In an equation, the linear relationship shows up if it looks like y=2x or y= 100 + 10x. There is a number in front
of the x variable and there may be a number that you add to give you the starting value.
2. Essential Questions
Questions that lead students to
Big Ideas.
What patterns in a problem suggest that it is linear? How can the linear pattern be represented in a problem, in a table,
in a graph, or with an equation?

1. Big Ideas
Student answers to EQs that
lead them to the Big Ideas
Any ordered pair (point) on a line or a table for a linear relationship can be used to find a solution to a problem. You
could also use the equation by substituting values of given in the problem into the equation and figuring out the
unknown. A linear relationship in an equation is represented by the form y= mx + b where “m” controls the slope of
the line and “b” gives the y-intercept.
2. Essential Questions

1. Big Ideas
Student answers to EQs that
lead them to the Big Ideas
The slope describes the steepness of a line. It is the ratio of vertical change to horizontal change. The slope can be
found in an equation if the equation is in the form y= mx + b, m is the slope. The slope can be found in a graph by
finding two points on the graph, find the difference between the vertical change and the difference between the
horizontal change, and then find the ration of vertical change to horizontal change. In a table, the slope can be found
by finding the change in 2 x values and the change in 2 corresponding y values. The slope is the ratio of change in the
y values to change in x values.

Month: February Samples and Populations
1. Big Ideas
Student answers to EQs that
lead them to the Big Ideas
Careful consideration of sampling techniques helps you to arrive at a good representative sample to draw conclusions
about the population.
Experimental probability is the number of times an event occurs/ over the number of trails.
Theoretical probability is the number of favorable outcomes/over the total of possible outcomes.
Odds in favor of an event is the ratio, (number of favorable outcomes: number of unfavorable outcomes).
Odds against an event is a ratio (number of unfavorable outcomes: number of favorable outcomes).
The probability of two unrelated events is the sum of the two individual possibilities.
The probability of one event following the other, in independent trails, is the product of the two probabilities.
2. Essential Questions

How can you develop a statistical investigation to answer questions about a population?
