Where is there a collection of math acitivities or projects to use in high school Algebra I, Algebra II, or Trigonometry that tie concepts to real-world careers?

Hi Kate

There are some activities of this type at the Apply Learning Network. These are lesson ideas, developed for teachers of Applied Academics curricula in British Columbia. The goal is to connect classroom learning with real-life, workplace applications that meet the learning outcomes for these subjects. The mathematics activities are aimed at Math 9 and 10. The URL for their site is http://cfaa.bridges.com/
