Practice problems.

Khan Academy is an excellent resource for parents, students, and teachers. It is basically a free online classroom with video lessons and the opportunity to try and solve problems in short online quizzes. It has resources for math, science, economics, and more. The resources are intended for a diverse audience with resources that vary from kindergarten all the way to high school and beyond. Teachers and parents can use it to help their students or children to get extra instruction and practice. Students can use it to help them develop a better understanding and to help them practice or study for tests. The site is well made and the information is credible which makes it an excellent resource. The content is obvious as Khan Academy has a drop down tab that allows you to navigate to all the different subjects and the audience is also obvious as each subject is broken down by which grade you are in. The content specialists are all experienced experts in all sorts of different fields and so the information can be verifiably accurate. Everything is well organized and the information is explained mostly through videos which tend to thoroughly explain the information. The website downloads very quickly and is aesthetically appealing. You can tell that it was professionally made. All of the links work and directions for using the website are fairly straightforward. All the videos and graphics serve a clear purpose which is typically to explain and illustrate different subjects. For example in the Trigonometry section a video is shown which illustrates a right triangle and the different ratios that can be used to solve the sides or angles of the triangle. The website is also extremely current as the copyright date is 2015.

Trevor Montgomery Khan Academy is a resource that students, teachers and parents can all use to encourage and promote positive attitudes and confidence for students in math by using activities that seem like games that actually help students practice and hone their math skills in a seemingly fun learning vessel. Khan Academy is also an extremely great resource for parents and teachers because they can not only track their child or students' progress, but also create activities and lessons for students to do outside of class and have their own online tracking guide. As far as content goes, the activities are based on grade level and category for the students, so as teachers, you have a lot of control as to what the material is. Additionally, you can add students to the class at any point and when necessary, look at the lessons from a "student view", where essentially you are logged in as a student and can take a crack at the lesson yourself to see if there are any errors or misconceptions. This is actually a great tool as a way to, in a sort, "proofread" your lesson or online homework activity assigned. You can also track skill progress specific to each of the students and when a child is done mastering a certain activity, you can keep track of that and maybe quiz them in class as a way of ensuring mastery of the concepts. The intended audience is parents, students and teachers alike. As a personal user and someone who knows they will use this resource as a future teacher, I have to say I give this resource a big thumbs up. So as far as easiness and fluidity of the website goes, it couldn't be easier to navigate. Especially for students, you couldn't ask for a better layout of a resource like this that clearly identifies goals and activities for you. As a teacher, everything is neatly organized in one place for you to navigate back and forth through students and activities.

Emily Phillips 8/31/2010 Overview: The purpose of this site is for a quick and easy way to solve simple math problems that only involve numbers, not concepts. The intended audiences are math students in lower levels of math. No available resources are provided. This site is basically a calculator with many functions, but can't do all of the functions that a more advanced graphing calculator can. While the site was easy to navigate, moving advertisements and pictures are distracting to the user. Content: A user can easily tell if this site will help their needs however in order to have full access to the site (i.e. the ability to see the steps to get the answer to the entered equation) they must be a member of the site. The information is accurate but since the answers are computer generated, once the user enters into calculus equations, they should be careful to check their answers with other sources because there is a chance that the answer could be one that is not the appropriate answer. There are no links to other sites that might be helpful or related to the subject. Design: The design was good and easy to navigate and follow. The pages within the site come up fairly quickly and the designs of each page are consistent. Some of the graphics contribute to the site but the advertisements definitely take away attention to the site.

Scott Chanthongthip on January 23, 2010 Overview: National Library of Virtual Manipulatives is a free website offered online to help teachers us visual aids to teach mathematics. The content is from the Utah State University and is edited by the university. Content is easy to navigate and understand because it focuses on students from K-12. Content: The National Teachers Council of Mathematics five content standards are listed vertically in a grid, while the grades for each of the standards are listed across the top of the grid. Navigation based on the content standard and grade level appropriateness is accessible because of this organization. Teachers just need to find the content standard and line it up with the appropriate grade level. Although the site has a version that it offers to schools many of the virtual manipulatives are easy to use as long as one's computer has JAVA capabilities. There are four different language options for the different virtual manipulatives, so it makes it easy to use in bilingual settings (English, Spanish, French, and Chinese). The main reason for this website is to offer teachers with computer technology to teach manipulation of different math areas when the physical manipulatives are not available. Teachers can also use the site to help explain concept clarity of hard to understand math functions. Design: The initial web page offers a grid of math standards and grade levels from K-12. Teachers can click on the appropriate link and it will lead them to more options on different subjects in the content areas. None of the links are broken for the virtual manipulatives. Design of the website is updated often by the USU. NLVM also allows users to select from four different languages.

Kaci Philpot Overview: The purpose of this site is to provide teachers and students with fun, interactive Math manipulatives online, because manipulatives help students to see visual relationships in Math and help to actively engage students. The website has the following standards for math education; numbers and operations, algebra, geometry, measurement, and data analysis & probability. Each standard has four different age groups to choose from: pre-k through 2, 3 through 5, 6 through 8, and 9 through 12. This website is one of the very few educational websites I have found that is free and clear or useless information and clutter. Content Summary: This website content quality is very high; it has an index chart on the homepage with grade levels and math standards. Each box on the chart is linked to a page of full of various virtual Math manipulatives. If you navigate to the credits page you can see who is in charge of creating what, however it does not provide information about or credibility of those individuals. It also does not have revision dates. But the site is well organized and has very rich content. The manipulatives are an excellent way to get students excited about learning math. Total yeses: 19 Total no's: 2 Total N/A: 3 Design Summary: The homepage of this site is very easy to navigate and understand, but it does not have very strong eye appeal at all. But the manipulatives are very useful and all have clear directions if necessary and all internal and external links work properly. It does not appear to have any outdated content, if Mathematics can even be outdated. My favorite link on this website is the link to the Spanish page. This would be very useful for teachers with ESL students; it helps to ease the language barrier. Total yeses: 22 Total no's: 2 Total N/A: 0

Chelsey Lynch 1/31/11 * Overview: This website is for the National Library of Virtual Manipulatives. The intended audience of this site is teachers, and students of all ages. The available resources are a wide array of virtual math manipulatives. This website is extremely useful to teachers because it provides children with a firm grasp on concepts by letting them learn directly through physical objects that enable students to visualize relationships and applications. * Design: This website is attractive and very easy to navigate. The main page of the website contains a large grid system which serves as a menu for the math content area and grade level. All information to contact the sites provider is given, and all the information is current. The instructions for the manipulatives are very easy to follow and the site even provides examples when necessary. This site has adequate graphics, though the music and sounds in games is a little dated and sometimes annoying. * Content: The authors of this site appear to be highly education and experts in this field. The purpose of this site is very clear and the content achieves the intended purpose effectively. This site is extremely interactive, well organized, and easy to navigate. I have personally used this site numerous times and love it. The only things I wish this site contained more of are links to websites that are similar to this or had further information.

Ryan Magrum Sept. 15th, 2011 Overview: The site is an online game site known as Armorgames.com consisting mostly flash games aimed at wasting time. However, there is a game Armorgames offers called CellCraft. While CellCraft is fundamentally a game, there are many aspects of it that are very educational. The goal of the game is to command a cell to grow and function as an animal and/or plant cell would and utilize all the functions and organelles as would an actual cell. The game explains all of the functions of the organelles you control and gives some information on the different parts of the cell, how the cell utilizes energy, and reproduces and fights off attack. The instruction in the game is similar to a high school biology class. Content: The game has multiple levels. Each level has a specific goal for the cell which the user controls. Each level also give some explanation of the new organelles available for use as well as the intentions of the antagonistic elements that an average cell has to deal with on a regular basis like infection and replication. The game has instruction for both plant and animal cells and all the included features of cells. It focuses on teaching the user how a cell operates and how to create a strategy to help the cell survive. The effects of the game are very close to reality - neglecting the very fine details. Design: It's a game. It comes with instructions. The game goes chronologically, so to speak, beginning from a time where the user can only move the cell around, to growing and fighting off infection, then to exploring new worlds and avoiding extinction. Just like in a biology class room, the student is expected to learn the basics and then think critically about problems using the basic knowledge to solve the problem, so does CellCraft. The game takes the user, educates the user on how a cell works (and I mean just about everything one would learn in a general biology class), and sends the user off to ke

How to use sine,cosine,tangent to determine side X in the triangle below Step 1) Based on your givens and unknowns, determine which sohcahtoa ratio to use Since we know the 67 angle, its adjacent side length and we want to know length of the opposite side, we should use tangent Step 2) Set up an equation based on the ratio you chose in the step 1 $ tan(67) = \frac{opposite}{adjacent} $ $ tan(67) = \frac{x}{14} $ (Let's Step 3) Cross multiply and solve the equation for the side length.

WatchKnow.org Michelle Petty, January 22, 2011 Overview: This site is aimed at students ages k-12, with a variety of educational portals from science to math to social studies. The site allows the user to select the area they are learning about, for example social studies and then within that category they can specify a content area like the Trail of Tears. Once the search results come back it offers a variety of information, however the information is only presented through videos and pictures. The site is easy to use and covers a wide variety of topics that makes it useful for students studying a variety of topics. However, without articles it makes using this site in research type projects difficult. Content: The website is clearly aimed at students and links to all content area taught to them. At the bottom of the site there is both a contact link and an about us & visions tab that informs the viewer who maintains the site, its goal, when it was last revised and how to contact someone with questions. When search results are found, the viewer can watch the video, go find the history of the videos to see where they came from and what the video has to offer and a separate tab to leave comments under. All of the video links work and are of good quality and offer a wide range in video content, from people reenacting historical events to math problems being solved step by step. Design: The website, while aimed at ages k-12, caters more to the younger audiences. The graphics used and even the color of font indicate that it wants to appeal to younger aged students. It is easy to navigate and use, and gives plenty of choices in videos and gives the appropriate information about the video that it can be used in an educational setting. I feel like this site would be very useful in replacing youtube videos used in class, because all of these videos are educational and meant for that use. I think I would use this site periodically, but I don't think I would

Overview: This website is a great way for an elementary teacher teaching math. Videos are the main point for this website. There are multiple videos that show elementary kids how to do the math that the teacher is presenting. This helps the kids because they get to see how to do the math in another way. But in addition it can help the teacher in finding new ways to teach the math in which they are trying to present.
