SHSU Math Conference

Embedded below is a slide presentation highlighting various Web 2.0 Tools that have been useful to me as a math teacher. I will be sharing and discussing these topics at the Sam Houston State University Math Conference on Saturday.

Five Helpful Tools for the Math Classroom

I am always on the lookout for really cool internet applications that I can use in math. If you know of others, please comment.

Equation Editor

You might notice that I have added an equation editor to the sidebar of my blog. Click on the format of the equation needed, make a few modifications and you have a very nice looking math equation. Normally, I use MathType on my own computer with MS Word. However, MathType is not free and not available in the cloud. Thus, when working on internet based computers, other options have to be utilized. I wouldn't want to have to type a whole worksheet using this gadget, but it isn't bad for one or two equations to use in a presentation.

Flash Cards

I am a big fan of Quizlet for vocabulary flash cards. I previously wrote about quizlet here. Quizlet is great for learning vocabulary. It is wonderful for differentiating instruction with minimal effort on the part of the teacher. This summer students in a PSAT Prep class typed in 16 word lists with definitions of 25 words each in under an hour. Afterward, they were instructed to concentrate on learning the first list. It was fun to watch students make their choice on how to learn. Some of them reviewed the flash cards electronically. Many of them played one of the two games available on quizlet. Several others practiced the words by taking a quizlet generated test. A few chose to learn the old fashioned way by creating index cards for their words or by studying the list on paper.

Students often are required to memorize many formulas in math as well as trigonometric identities. I wasn't able to figure out how to get quizlet to handle a math formula. Then I discovered another flashcard application called Cobo Cards that uses Tex to make beautiful flash cards with equations. Once I learned how to copy and paste the Tex commands into Cobo Cards, writing equations was a breeze. Click here to see my set of trigonometric identity cards.

Graphs

Math teachers use many graphs on their tests and worksheets. Students, too, need to be able to use internet based graphing options if they are to create presentations. My twitter friend @JackieB introduced me to Graphsketch shown at the left.



Another option for creating graphs would be to utilize the computational knowledge engine at WolframAlpha. I typed in an expression, then used Photo Filtre to copy it and save as a jpeg. It does not have the grid lines like graphsketch, but it is very well done.




Animoto

I found the animoto embedded below at http://teachingcollegemath.com/?p=654. I thought it was great and plan to show it to my students once school starts. Hopefully, this will help them understand the concept of a function. Another use for math animotos might be to illustrate a theorem or develop a proof in geometry. Students could create an animoto illustrating the steps of solving an equation. The site mentioned above describes the method for creating the function animoto using PowerPoint slides. I think Google Doc Presentation slides could easily be substituted. Each slide would need to be saved as a jpeg and uploaded to animoto.






Games

One of the best sites for math games is coolmath.com. Here you will find all kinds of games for all levels, elementary to secondary. The games are interactive and just plain fun. Be prepared to lose a few hours while exploring this site.

I hope that you will find these tools useful as well. Please leave me a comment regarding your favorite internet math tool.

Quizlet

Quizlet is a flashcard application. It is the best one I have seen so far. It allows the user to enter words and their corresponding definition or fact associated with the word. Once the flashcards are created, students may learn them the old fashioned way by flipping the card electronically. They can also respond by typing in the corresponding word when given the definition. The features that I like are the quizzes that it automatically generates. The student is presented with several different modes of answering questions. The quizzes can be fill-in-the-blank, multiple choice, matching, or true/false or all of these. Please click on the link http://quizlet.com/demo/ to see how easy it is to create a flashcard set.

Students or teachers can create the flashcards for a private or public audience. If they are totally private, then only the creator can see them. They can also be associated with a group in which the creator provides members of the group with a password to access the cards. Finally, they can be totally public for anyone on the web to use. Instead of creating a set, I chose a public set of geometry flash cards to use. If you choose this method, be sure to check that all of the definitions are correct.

I see this as a great way to learn vocabulary words or a foreign language. Quizlet includes a couple of games to play with the flashcard set. I like the scatter game the best in which the student drags the definition on top of the associated word or vice versa to make both of them disappear. The game stops when the board is cleared. The student is told how much time elapsed and is asked if they want to play again to beat their time.
