In Algebra I we have been learning linear and multi step equations. This is a bit of a review from what we did last year. So far we have done one project. The project we did was making an algebra book with our own written equations. The 21st century skills I used to make this project was thinking and problem solving. I used thinking and problem solving because we had to figure out the solutions to the equations that we made and we had to make several stories to make the equations work.
