Finding the Missing Angle of a QuadrilateralSteps for Solving:1. Add the known angles.

2. Subtract that sum from 360.

3. If there is a picture, check to see if the angle is reasonable. (obtuse, right, acute)

Writing Equations Using Sequencing Tables

Look for a relationship betweenthe x and y data.

Test the rule on the rest of the pairs of numbers:

Test each answer choice!

Page 3: Finding the Missing Angle of a Quadrilateral

Probability as a FractionStart with the first answer choice. Do this for each one until you get a fraction that works!

1. Organize your info:Write in a column how much of each color.

2. Add to find out how many color tiles total. That will be the denominator.

3. The question only asks about blue tiles. (preferred possibility) Write the number of blue tiles as the numerator.

4. Simplify.

5. The question asks which answer choice results in 1/3. If the fraction you end up with is not 1/3, try the next answer choice.

Line Plots

It consists of a number line that includes the values of the data set.

An X is placed above the corresponding value each time that value appears in the data set.

A line plot represents a set of data by showing how often a piece of data appears in that set.

Writing Equations for Word ProblemsSteps for Solving:

1. Organize the information.

2. Solve the problem, even though the question doesn’t ask you for a solution.

3. Select the answer choice that describes your solution.

Using a Protractor to Measure AnglesNotice that one of the rays of angle RNP is not lined up with the zero.• Follow each ray and record where each intersects the protractor. • Subtract to find the difference of those two numbers.• Is your answer reasonable? An acute angle should measure less than

90 degrees. An obtuse angle should measure greater than 90 degrees.

Numbers in a Sequence• Starting with the first number.

What would you have to do to that number to result in the second number? Write that down.

• Starting with the second number, what would you have to do to that number that would result in the third?

• Continue this process through all of the numbers.

• Use that pattern to predict the next two numbers if that pattern continued.

Elapsed Time• On a number line, mark the

time he left.

• Jump ahead by 1 hour jumps, stop before you pass the time he returned.

• Then, jump ahead using minutes until you reach the time he returned home.

• Count up the hours, and count up the minutes.

Page 14: Finding the Missing Angle of a Quadrilateral

Finding the MeanMean = average• Add the numbers.

• Divide by how many numbers you have.

What is the mean number of the jacks brought by her friends?

Finding the Missing Angle of a Triangle

Steps for Solving:1. Add the known angles.

2. Subtract that sum from 180.

3. If there is a picture, check to see if the angle is reasonable. (obtuse, right, acute)

Mean, Median, Mode, and Range

Mean is the average. (add the numbers. Divide by how many numbers there are.)

Median: With numbers arranged in order from least to greatest, the median is the middle.

Mode: The number that occurs most often.

Find the least value, greatest value, mean, median, mode, and range of the data set.

Feet and Inches

How to Solve:For each section of rope, add the feet together (leave the inches for now).

Now, add just the inches together.

Divide the inches by 12. Add that number to the feet that you had in the first step.

Look at the remainder to see if you should round up or down to the nearest foot.
