Evaluating Expressions
One Step Equations
Tip: Use inverse operations.
Mean, Median, and Mode
Tip: Line up the decimals vertically and compare from right to left.
Tip: Line up the decimals and add normally, then drop down the decimal.
Tip: Line up the decimals and subract normally, then drop down the decimal.
Tip: Move the decimals to the right and write how many places to the right the problem. Then multiply normally and move the decimal that many places from the right.
Tip: Start by moving the decimal in the divisor and remember to move the decimal in the dividend the same number of times.
Conversions
Tip: Use K H D B D C M for the metric system.
Practice Problems (Metric System)
Practice Problems (Mixed Units)
Perimeter
Tip: It is the same for all shapes: just add up the sides.
Area
Tip: Squares (Area = base x height), Rectangles (Area = base x height), and Triangles (A = base x height divided by 2) Write the formula, plug the numbers in below it and solve it below that.
Circles
Cherry pie delicious, apple pies are too.
(C = pi x d) , (A = pi x r^2)

Show me video 2 (improper fraction to mixed number)
Tip: Find a common denominator, then add the numerators and keep the denominator.
Tip: Find a common denominator, then subtract the numerators and keep the denominator.
Practice Problems 2 (Adding and subtracting mixed numbers)
Tip: First REDUCE, then multiply the numerators and denominators.

Proportions
Use cross products.
Show me video 1 (Are they equal?)
Show me video 2 (Solving for an unknown)
Practice Problems 3

Practice Problems 1 (decimals to fractions)
Practice Problems 2 (fractions to decimals)

Adding and Subtracting Integers
SKA (Same, Keep, Add) and DBS (Different, Bigger, Subtract)
Multiply/Divide first. If the signs are different, the answer is negative. If the signs are the same, the answer is positive.
Tip: Walk over to the elevator, then take it either up or down to your floor.

The Common Core State Standards Initiative is an effort to ensure that all students in public schools in America acquire the skills and knowledge they need in order to be prepared to achieve success at college or in the workforce.

The federal government is not responsible for this initiative; it was developed at the state level by government leaders and education professionals who were concerned about the lack of national standards for the education of children. As of this writing, 45 states have voluntarily adopted the standards, along with three territories and the District of Columbia.

The limitations in the quality of research in sex education have been highlighted by several authors in the past two decades (Kirby and Baxter, 1981; Card and Reagan, 1989; Kirby, 1989; Peersman et al., 1996). Due to these deficits in the quality of research—which resulted in a reduced number of studies that met the criteria for inclusion.

After reading, there are questions for you to answer.

Before the initiative, each state set its own educational requirements, which led to a situation in which some states had much lower standards than others. Not only was this unfair to the students who were being held to the lower standards, it also made it very difficult for parents, colleges, and employers to gauge the value of a high school diploma, because requirements varied so greatly.

With one set of standards for all, everyone concerned is better able to judge how effectively a school is teaching its students.

Having a consistent standard across the United States is not a magic solution that will solve all the problems in our nation’s schools, but it will certainly play a key role in education reform, for several reasons. Having one standard will allow parents and students to know exactly what will be expected of students in order to earn a diploma.

Teachers will also have a clear expectation of what’s required of them, and education programs at colleges and universities will be better able to train our nation’s future teachers. In addition, educational publishers will have benchmarks to guide them in developing textbooks and other educational materials. Testing will also be more effective with uniform, clear-cut standards across the board.

This does not mean that all schools in America will become carbon copies of each other. Common Core standards set specific goals, but it will be up to the administrators and teachers in each school to determine the best methods of achieving those goals.

They will have the flexibility and autonomy they need to give their students a great education, while having clear outcomes to aim for. The standards offer teachers and administrators guidance without taking over their classrooms and turning them into automatons.

The standards are divided into two main categories: Mathematics, and English Language Arts. Standards have been developed only for these two subjects, as they are the foundations upon which students will build to master all other subjects. In each category, there are detailed and objective standards provided for every level, from kindergarten to 12th grade.

Students will be evaluated on a regular basis to measure their progress against the standards for their grade level, and whether or not they receive a high school diploma will depend in large part on their meeting these standards.

While teachers will play a key role in helping students gain the skills and knowledge required by these standards, it will be up to the student to actually pass the exams. To assist students who desire to excel and have the initiative to seek improvement and mastery of the standards on their own, we have provided Common Core practice questions and answers for self-testing purposes.

By taking advantage of these resources, students can determine their strengths and weaknesses, and pinpoint those areas where they may be falling short of the standards. They can also use the questions and answers as a direct means of improvement. Parents should encourage their children to make use of these resources, and monitor their results, as study after study has demonstrated conclusively that children whose parents take an active interest in their education almost always excel.
