# Algebra 1 Help

iTunes U Textbook: Got an iPad/iPhone/iPod? Download the Algebra 1 iTunes U “textbook” for help! It has videos and lessons on everything we are learning.  My mom is retaking Algebra 1 right now!

Spark Notes: Summary of all topics studied in Algebra

Explore Learning: Great site with visual aids for many concepts. Henrico County has a license for the students to access this.  Contact if you need help logging in. You can browse by topic, SOL Standard, or textbook chapter.

Khan Academy: Khan Academy forces students to gain “fluency” in their math skills so that they can do the skill quickly and correctly. Practicing any skill on Khan Academy will improve your math skills, which everyone needs!

Math Dictionary for Kids: Easy definition with examples (and some times a little activity).  The charts are also helpful study guides and summaries.

Textbook: You also have your textbook(s) that you can use!
