# How do you do mean in math?

Mean = Average (Mean means Average) You add the set of numbers together and then divide the number of numbers in the set. For example... If you had a set of numbers 75, 85, 65…, 53 and 77, you add up all the numbers which equals 355. Then you divide 355 by 5 because there is 5 numbers in the example at the top (the 5 numbers are 75, 85, 65, 53 and 77). Your answer will be 71. That's how you do mean in math. (MORE)

# Math Manipulatives To Make Learning Fun

Math is one those subjects that can be taught through hands-on manipulatives. This approach to teaching math is not only interactive but also fun for students. There are many …math manipulatives available for math instruction. These math tools can be used within the classroom, home or during a tutoring session. These are great items that will make learning math easier and enjoyable.Base ten blocks are an excellent tool to teach students a variety of math skills. Students can use base ten blocks to learn numeration skills such as counting, place value, addition & subtraction, multiplication and division. There are four different base ten blocks: cubes (ones), rods (tens), flats (hundreds) and blocks (thousands). Base ten blocks can be found in most classrooms because it is a such a versatile tool throughout many grades.An Abacus, also known as a counting frame, is a math tool that is known for being used many centuries ago. However, many classrooms today contain this tool for teaching math skills. This ancient math tool helps students with counting, patterns, color recognition as well as more advanced skills such as addition, subtraction, multiplication and division. This "wooden" calculator is an invaluable tool that is known to help with problem solving skills.Two-sided color counters or "chips" are another invaluable tool that is found in many classrooms. These two-sided color counters can be used for the primary grades for counting, sorting and color patterns. However, the older elementary grades benefit from these counters for addition, subtracting, multiplication and division. Students can also use this tool when learning fractions and probability. This versatile tool can be found in almost all elementary classrooms.Dice are a tool that is often synonymous with game boards however dice are an excellent math tool. Dice are great for all ages and grade levels. They are used to reinforce simple concepts such as greater or less than, numeration skills and one to one correspondence. However, they are also used for more advanced skills such as multiplication, coordinate pairs, and learning the difference between prime and composite numbers. Dice are not just for traditional games, they are a very powerful math tool."The essence of mathematics is not to make simple things complicated, but to make complicated things simple." - S. GudderLearning math with hands-on math instruments allows students to engage in an interactive and meaningful way. Students are able to learn and deepen their understanding of math skills through these tools and then are able to apply their knowledge to pen and paper.

# SAT Math: What Students Should Know to Score Well

One-third of a student's SAT score is based on knowledge of high school-level mathematics. In order to excel on this portion of the SAT, students should be aware of what math… skills will be tested so they can work on retaining and practicing them. In addition, it's valuable for students to become familiar with the way the SAT test formats math problems.The College Board, which creates and distributes the SAT, lists numbers and operations as the first area tested in math. Some of these questions test students' knowledge of terminology, such as consecutive integers, prime numbers, rational numbers, intersection of sets, and units digits. Many of the concepts covered by numbers and operations questions are things students learned early in high school or in junior high, so they may seem easy, but beware: The SAT can create a very difficult problem using basic math concepts.The College Board assumes that most students will take the SAT in the spring of their junior year of high school. Nationwide, most high school juniors are taking Algebra II, so no math concepts beyond Algebra II are tested on the SAT. In addition, most algebraic problems cover concepts students learned in first-year algebra. Students should know how to solve linear and quadratic equations, work with exponents, take the absolute value of a term, and solve algebraic function questions.The geometry tested on the SAT is limited to shapes most students are familiar with: triangles, rectangles, circles, pyramids, spheres, cubes, and basic polygons. Students will be asked to work problems involving coordinate geometry, including lines, distance, and slope. Questions test knowledge of parallel and perpendicular lines, as well as properties of triangles, including the Pythagorean Theorem and isosceles, equilateral, and special right triangles.High school students are not expected to have taken a class in statistics in order to successfully complete the SAT. The data analysis, statistics, and probability problems on the SAT cover material and concepts students will have been exposed to in basic math and algebra classes. Students need to interpret information presented in tables and graphs, calculate means, medians, modes, and basic probability. These questions make up 10 to 15% of the SAT math section.Because high school juniors are not assumed to have completed classes in trigonometry or calculus, no questions on these subjects appear on the SAT. Students do not need any knowledge of trig functions or pre-calculus for the SAT.A student who knows all of the mathematical concepts tested on the SAT will still need to use problem-solving skills to answer questions successfully. The SAT math sections include questions of all levels of difficulty, from easier to extremely hard. The more-challenging questions require more steps to move from questions to solution, providing more opportunity for errors, and engaging higher level thinking skills that may challenge a student's abilities.The ACT, another college admissions exam, does contain questions dealing with basic trigonometry concepts, but these questions make up less than 10% of the ACT math section. In contrast, students do not need any knowledge of trig functions or pre-calculus for the SAT.To ensure the best scores possible on the mathematics section of the SAT, students should begin by learning and retaining the concepts taught in their high school math classes. Prior to taking the SAT, students should review all the material covered on the test and familiarize themselves with the questions. By knowing not just the content likely to be covered on the SAT Math section, but also how they will be tested on their knowledge of that content, students can make their best-possible scores.

# What is the mean in math?

The average. To get the mean you add all of the numbers in the list together, then divide the answer by how many numbers there are. Example: What is the mean of 32,… 88, 44 and 16? 32+88+44+16=180 180 dived by 4(which is how many numbers there are)=45 The mean is 45 the mean in math is the average. to find the mean or average of a set of data add all data and divide by number of data example: find the mean of 10, 26, 14, 20, 35 add all the numbers: 10+26+14+20+35=105 there are 5 numbers so divide sum by 5: 105/5=21 the mean or average is 21 (MORE)
