This system services both Math and Science teachers as a resource.  TxAIR contains content covering grades 3-8 in math and science, Algebra I, and Algebra II, Geometry, Integrated Physics and Chemistry, Biology, Chemisty, and Physics TEKS.  You can find many questions on certain TEKS to enhance the student's learning, receive feedback and is all web-based.  TxAIR is located under Project Share and must be loaded for specific teachers.  If you feel that your teaching would be enhanced by this program and do not have this on your Project Share Portal, please email me.
