# Teacher resources

The worksheets in The Old-School Typewriter Algebra Workbook are aligned to the Common Core State Standards for Mathematics for high school algebra with some middle school topics included for reinforcement. For your convenience in planning, they are listed here organized both by standard to help you find an appropriate worksheet, and by worksheet to find the corresponding standard for lesson plans that require them.
