Continue Justin LewisGetty Images Mathematics can get quite tricky. Fortunately, not all mathematical problems should be incomprehensible. Here are five current math problems that everyone can understand, but no one has been able to solve. Advertising - Continue reading below Collatz Hypothesis Select any number. If this number is even, divide it into 2. If it's weird, multiply it by 3 and add 1. Now repeat the process with the new number. If you keep going, you'll end up at one. Every time. Mathematicians have tried millions of numbers and they have never found one that didn't end up at one after all. The fact is that they have never been able to prove that there is no special number out there that never leads to one. It is possible that there is some really large number that goes to infinity rather than, or maybe a number that gets stuck in a loop and never reaches one. But no one has ever been able to prove it for sure. Moving the sofa is a problem so you move into a new apartment and you try to bring your sofa. The problem is the hallway turns and you have to fit your sofa around the corner. If it's a small sofa that may not be a problem, but a really big sofa is sure to get stuck. If you're a mathematician, you ask yourself: What's the biggest sofa you could fit around the corner? It doesn't have to be a rectangular sofa either, it can be any shape. This is the problem of moving sofas. Here's the specifics: the whole problem is in two dimensions, the angle is 90-degree angle, and the width of the corridor is 1. What is the largest two-dimensional area that can fit around the corner? The biggest area that can fit around the corner is called-I'm kidding, you don't-sofa permanent. No one knows for sure how big it is, but we have some pretty big sofas that work, so we know that it should at least be as big as they are. We also have sofas that don't work, so it should be smaller than those. All together, we know the sofa constant should be between 2.2195 and 2.8284. Perfect Cuboid Problem Remember the pyphagora theorem, A2 and B2? The three letters correspond to the three sides of the right . In the Pythagoras triangle, and all three sides are whole numbers. Let's extend this idea to three dimensions. There are four numbers in three dimensions. In the picture above, they are A, B, C and G. The first three measurements of the box, and the G is diagonal running from one of the upper corners to the opposite lower angle. Just as there are some where all three sides are whole numbers, there are also some boxes where three sides and spatial diagonals (A, B, C and G) are whole numbers. But there are also three more diagonals on three surfaces (D, E and F), and this raises an interesting question: can there be a box where all seven of these lengths are The goal is to find a find where A2 and B2 and C2 and G2, and where all seven numbers are integers. It's called the perfect cuboid. Mathematicians have tried many different possibilities and still have not found one that works. But they also couldn't prove that such a box doesn't exist, so hunting for the perfect cuboid. Inscribed square problems draw a closed loop. The cycle doesn't have to be a circle, it can be any form you want, but the beginning and end must meet and the cycle cannot cross itself. You should be able to draw a square inside the loop so that all four corners of the square touch the loop. According to the written square hypotheses, each closed cycle (in particular, each plane of a simple closed curve) should have a square, a square, where all four corners lie somewhere on a loop. This has already been decided for a number of other forms, such as triangles and rectangles. But the squares are complex, and so far the formal proof has eluded the mathematicians. The happy ending problem of the Happy End problem is so named because it led to the marriage of two mathematicians who worked on it, and Esther Klein. In fact, the problem works like this: make five points on random places on a piece of paper. Assuming that the dots are not intentionally located, say in a row, you should always be able to connect four of them to create a convex , which is a four-sided shape where all angles are less than 180 degrees. The essence of this theorem is that you can always create a convex quadrilateral with five random dots, no matter where these points are located. So that's how it works for the four parties. But for the , the five-sided shape turns out you need nine points. For the it is 17 points. But other than that, we don't know. It's a mystery how many dots are required to create a or any large shapes. More importantly, there should be a formula to tell us how many points are required for any form. Mathematicians suspect that the equation is M'1'2N-2, where M is the number of points and the N is the number of sides in the form. But so far, they've only been able to prove that the answer is at least as big as the answer you get that way.

Concepts considered include: money, addition, subtraction, problem with word, subtraction and talking time. You'll need an Adobe reader for the following sheets. Second-class sheets were created to emphasize concept, and should not be used in isolation to teach the concept. Each concept concept taught using mathematical manipulative and many specific experiments. For example, when learning to subtraction, use cereals, coins, jelly beans and provide a lot of experience with the physical movement of objects and print the number of offer (8 - 3 No. 5). Then move to the sheets. For word problems, students/students need to have an understanding of the required calculations, and then the impact of word problems are needed to ensure they can use computing in genuine situations. At the beginning of the factions, a lot of experience with pizza, fractional bars and circles should be used to provide understanding. The factions have two components to understand, parts set (eggs, rows in gardens) and whole parts (pizza, chocolate bars, etc.) I have someone who is a fun game to enhance learning.

Sheets are usually printed educational resources that, combined with good teaching, can help students learn important concepts. Sheets are most often used as formative assessments, which are used by teachers in order to ... in the process of assessing the student's understanding, learning needs and academic progress during the lesson, Or, of course. There are several arguments against the use of sheets, and unfortunately the sheets do get a bad reputation as they are often associated with hard work. The workshees also perpetuate the culture of class-me in education: the belief that every assignment, however trivial it may be, performed by a student deserves to be evaluated. Sheets are also preferable in replacement lesson plans. These sheets are student work that remains from a teacher who should, for one reason or another, be out of class. Sheets are often collected, but not graded, by substitutes. Typically, this means that the teacher returns to the classroom behind in a score-inundated pile of sheets in the classroom. Since sheets are added to a bunch of documents for teachers to review along with tests, quizzes, lab reports, or major projects, time evaluation commitments is one of the biggest arguments against their use. When they are completed, these low-level student work pages can add to a bunch of teacher evaluation documents. As a rule, the most effective sheets are those that serve as formative assessments. These sheets can be used by teachers in several different formats in each area of content. These forms can be printed as printed copies or available digitally, and they may include: short answersmultiple selection of questionsmatching exercisesproblem solvingfill-in-the-blank word searcheswordcrosss Workshee can be given scores (points or letters of class) or evaluated just to complete. In any case, the weight sheets given in the classification program should be minimal, for example, 5% or 10%. Because the teacher has a limited amount of time to evaluate the sheets, the teacher should consider ways to speed up the classification process. By speeding up the classification process, the teacher is better able to provide each student with feedback in a timely manner by taking the classroom's heart rate in teaching. These three strategies also increase the amount of work that students do, while reducing the amount of work that teachers do. By thaddeus Guldbrandsen (Vice-Provost for Research and Interaction at Plymouth College): We know from the latest neuroscience training that the person who does the job does the training, here are three separate strategies aimed at putting the student student's work on and speeding up the classification process. Each of them gives the teacher the opportunity to quickly wrapped up the documents and return them to the students. These three strategies also make sure that the student is doing all the necessary work and that the teacher can quickly use the results to inform the instructions. By selecting the most important questions in advance or using a randomizer of questions or combining student responses, teachers can help with the work of the sheets. There are several resources to search for sheets of content normally provided by publishers or educators can create their own with an online list generator. Use digital tools to select questions on sheets. Mark Trigalo/GETTY Images STRATEGY: Even with a few questions, each sheet in each area of content contains a high priority question (or two) that a teacher can use to determine whether a student understands content or concept. In this strategy, students first answer all the questions on the sheet. After the sheet is completed and before the student forms a complete sheet, the teacher announces that only one (or two) of the issue (s) will be considered for evaluation. The teacher can choose which question (s) will be evaluated in advance. This statement should be made only after the students have washed the sheets. For example, in a class of 26 students, a sheet of 12 questions would generate 312 answers for evaluation and then calculation for the final class. Using this method, the teacher will score only 26 questions in total. Students should be given a few minutes to undergo a double check to consider the answer to this particular question before handing over the sheet in. Here, it is a student who does the job and do the teaching. SUGGESTIONS: The choice of question will be used to assess the behavior of students can be done in advance. There are times, however, when the teacher may want to use a randomizer (order or choose a question to reduce bias and interference). The teacher can choose a number (roll dice, moderately eskimo sticks, etc.) and announce that number in the class as a sheet issue number to be evaluated. (For example: Today I will be evaluating the question #4 only.) The following digital tools allow teachers to choose which question students should answer. Wheel Solve: WheelDecide Ltd. helps us all make decisions when the coin just lacks parties.... Wheel Decide has also established itself as an attractive tool for business, education and entertainment. RandomThing: Enter the list of commas of divided items question 1, question 2, question 3) Click Pick one! There will be one choice. Students complete their work in the group; The teacher announces that only one question will be evaluated; The teacher chooses the question OR uses one of the randomizers above. Have students work together on a sheet with each student responsible for the question he or she chooses. kali9/GETTY IMAGES STRATEGY In this strategy students work together as a group on a sheet with each student responsible for one (or two) question (s) on the sheet. All the questions on the sheet will be evaluated, but the number of sheets collected for the class decreases. For example, Class 27 can be placed in groups of three (3), which means that there will be nine (9) sheets collected. When a teacher evaluates a sheet, each student receives a grade based on their individual response (s). These activities are linked to the standards promoted by the 21st Century Productivity and Accountability Partnership. The standard recommends that students effectively collaborate and collaborate with teams. Using this strategy, even with a regular sheet, is an example of how students should engage in critical thinking, communication skills and collaboration. These skills are promoted by Tony Wagner and the Group of Change Leaders at Harvard Graduate School of Education. WARNING: Students can choose their groups or be assigned. Students will be able to choose the question he or she chooses. Teachers may need to prepare for this kind of group work that allows students to help each other with answers, a form of peer-to-peer coaching. The following apps allow teachers to select students for groups for sheets. Team Shake: (iTunes/Android) It's easy to create commands by shaking up multiple PhoneCreate class lists for easy useadd names using a keyboard or Stickpick contacts: (iTunes) Popsicle sticks are digital - and they can do much more than just display names. Random Students: (Android) Free version allows teachers and teachers to use the app for one class of up to 200 students. The device says the name out loud track correct and wrong answers create custom and random student groups to collect the same kinds of sheets in groups and then from the entire class. Ableimages/GETTY IMAGES STRATEGY: In this strategy, all students complete the sheets. The teacher then collects sheets from several rather than all class members. The choice can be based on pre-set lists or using a digital randomizer (order or choose a student's name to reduce bias and interference). For example, if there are 24 students in the class and the randomizer selects six names, all student work will be reviewed within four weeks. Using a name collector or randomizer, the teacher can announce, Today I will collect sheets from the following students: Marco, Eliazar, Jessebet, Kisha, Misha, and Truman. NOTE: This strategy should be used with diligent record keeping, so that each student was included in the randomization and had the sheet evaluated. Students should be aware that even if the paper was collected a week earlier, their names may still be in the name selection pool. WARNING: This strategy is best used with sheets that are similar in content. For example, if a teacher uses the same blank-filled sheets every week or math problems every day, this strategy is effective in assessing the skill sheet. The following websites allow teachers to digitally choose the names of students or teams; Each app allows students to be removed from the previous selection: Class Tools-Fruit Machine / Randomizer Machine: Entry list of questions (by number) and then click either typewriter or fruit machine.
