Welcome to the Algebra2go prealgebra resources page. Whether you are attending Saddleback College's prealgebra class (math 351), taking a prealgebra class at another school, or need to refresh your math skills for a business or science class, we have tools that can help you. We have five primary types of study materials: class notes, video lectures, video worksheets, practice problems, and practice quizzes. For some topics we have some extra tools to assist your studies. Whichever materials you decide to use, we would appreciate your feedback. Please let Professor Perez know what you liked and didn't like about these materials by sending him an e-mail.
Perhaps our most popular tools are the video lectures. Attend Professor Perez's lecture alongside his favorite student, Charlie. Each lecture focuses on a particular skill set which is vital for success in prealgebra. We are in the process of adding closed captioning to all of the prealgebra videos. For a few videos we have versions with an ASL interpreter for the hearing impaired. We hope to have more of these in the future. The videos are available in three formats.
Windows Streaming Media: These are .wmv videos. If your computer doesn't already play this format, you can download the free Windows Media Player to watch them.
YouTube: These are flash videos. They are lower quality than the windows streaming media videos, but YouTube videos can be played on a wider range of platforms including the iPhone and Wii. Since YouTube limits the length of video clips, some of the videos have been split into multiple parts.
TeacherTube: These are flash videos similar to the YouTube versions, but TeacherTube videos are better quality and do not need to be split into multiple parts.
Every video is accompanied by a worksheet that mirrors the presentation so that you can work along with Charlie during the video. This kind of active learning process is a particularly good way to increase retention. The worksheets are saved in the .pdf format. If your computer doesn't already read these files, you can download the free Adobe Acrobat Reader.
Charlie isn't the best note-taker, but fortunately for him (and for us), his friend Candice is. She has loaned her comprehensive, hand-written notes on every lecture to Charlie and you can see them here. We plan to add Spanish versions of the notes soon. The notes are saved in the .pdf format. If your computer doesn't already read these files, you can download the free Adobe Acrobat Reader.
Professor Perez has also put together a collection of homework problems for many videos. The homework sets are saved in the .pdf format. If your computer doesn't already read these files, you can download the free Adobe Acrobat Reader.
Some videos are accompanied by an online practice quiz so you can determine when you are ready to move on to the next topic. Just fill in the blanks with the correct answers to each question. When you finish, Charlie will let you know how you did.
For some topics we have extra tools to help you master the math. The tools come in two varieties.
Printable Tools: These are resources like blank graph paper or blank number lines. They can be printed and used to practice problems from particular topics. The notes are saved in the .pdf format. If your computer doesn't already read these files, you can download the free Adobe Acrobat Reader.
Online Tools: These are interactive web pages which are available online. They don't require access to a printer, and can even be used on many mobile devices. An example would be an interactive number line for practicing integer addition.
