**Videos from Math TV**- This library contains over 10,000 videos, from basic math through calculus. Almost every set of videos has one conducted in Spanish, by a native speaker. Video instruction is asynchronous, and allows students to repeat, rewind, and review. Most topics have a choice of instructors for students to choose from so that students can see slightly different approaches and strategies to solving each problem.2.

**Project Interactivate**- Interactivate is a set of free, online courseware for exploration in science and mathematics. The site is structured around collections of activities, lessons, and discussions. You can reach listings of each type of resource either by following the prominent links on the front page, or by using the "Jump To:" pulldown menu located at the top of every page. Interactivate provides alignments with a number of common math texts. For every lesson of every chapter of an aligned text, they provide links to relevant Interactivate activities, lessons, and discussions. To access the list of supported texts, pull down "Textbooks" from the "Jump To:" menu.3.

**Would You Rather?**- This site presents a picture with a mathematics problem that asks, "Would you rather?" Most of the questions have a financial aspect to them. One example is**this challenge**that asks "Would you rather go on a 5 minute shopping spree in the store of your choice or get a $2,000 gift card to the store of your choice?"**Print the provided worksheet**and have your students use it to analyze the choices presented to them in the challenges.4.

**Desmos**- A free graphing calculator that can be used in a web browser on a Chromebook or any other computer using the Chrome browser. It is also available for mobile phones. Desmos has a robust**website full of activities and lessons**to use in your classroom.5.

**GeoGebra**- GeoGebra is an interactive geometry, algebra, statistics and calculus application, intended for learning and teaching mathematics and science from primary school to university level. Math teachers and students can use it to build interactive models of problems and concepts. The**GeoGebra YouTube channel**provides tutorials to help you get started using GeoGebra on your laptop, tablet, or Chromebook.6.

**Brightstorm Geometry Videos**- Dozens of videos of a teacher using a whiteboard to explain geometry concepts. Watch videos about what you didn't understand in class or to deepen your understanding.**Online Math Learning: High School Geometry**provides embedded views of the Brightstorm videos with short, written descriptions of the concepts taught in the videos.

**Kahn Academy**- Video tutorials for Arithmetic, Algebra, Geometry, Calculus and more. Note - These are housed on "You Tube" so they may be blocked in some districts. With a free account, teachers can find standards-aligned content; assign practice exercises, videos and articles; and track student progress. Note: Students can join your class via a class code, but they will need an email-based login.8.

**SparkNotes: Math Study Guides**- These guides summarize and review mathematical concepts in a text-based format. You will find guides for PreAlgebra; Algebra I and II; Geometry I, II, and III; and more.
