Gov. Rick Snyder has signed changes in Michigan's high school graduation requirements affecting math, foreign language, and health and physical education classes.

Two laws signed Wednesday rewrite a provision that gives students flexibility to meet the algebra II credit by taking welding or another career and technical education class. Snyder says the goal is giving K-12 districts more flexibility to weave algebra II into career tech programs while maintaining the ``necessary rigor.''

Michigan requires students to complete two years of a foreign language in high school. Now students can also meet the requirement in grades K-8.

Students who now need one year of health and physical education will get some flexibility. They can take a half-credit of health and count extracurricular activities to meet a half-credit requirement in gym.
