Curriculum frameworks, classroom resources, and more

**Angle-a-trons** (2:04) Measure angles without a protractor! A little too fast to show in class without support. Try teaching the concept yourself, presenting it with supports, or sharing it in a place where students can repeatedly view it.

**Surface Area of a Rectangular Prism** (4:42) A visual explanation. Great use of vocabulary; plenty of opportunities to add discussion about mathematical properties, algebraic thinking, and alternate solution pathways.

**Area of a Circle Formula Explained**(2:47) A visual explanation.

**Surface Area of a Cylinder** (3:08) A visual explanation. Could your class use the rules of algebra to connect this explanation to the formula given on the GED formula sheet?

**Pythagorean Theorem** (2:37) An interesting explanation a little beyond others that I have seen.

__ Exploring Functions and Graphing Worksheet__ For repeated use in conjunction with prompts that you provide, this worksheet gives students opportunities to practice skills and connect concepts related to functions and graphing.

**Poll Everywhere**** ** A simple polling tool that works via texting or computer; you can show real-time results to class. Easy to make and share.

**Voki** Create an avatar to use in your classroom.

**GED**®** Mathematics Formula Sheet**

** Annenberg Learner** Multi-level videos, interactives, and lesson plans
