Algebra 2 Week 8

We finished our study of systems of equations and introduced matrices. The last section of the systems of equations was more story problems. Most students feel that story problems are difficult. I hope I gave them so tricks to doing these. Make sure you ask questions or watch the YouTube videos if you don’t understand. We started Unit 4 Matrices. These are just boxes to organize data. We learned how to add, subtract, and to do a type of multiplying called scalar multiplication.  I will be teaching you how to do them on your calculator. I challenged you to experiment to figure out how to do these on your own. You can play around or consult Google if you want. I also introduced the second level of the formula madness. I posted the answers for these in the Parent folder. You have 2 weeks to practice this before the official quiz. I will be surprising you next week with a in class quiz to see how you do and to see how many of you read these wrap up paragraphs. The quiz will just be for practice and not a grade. The practice quiz will have 20 questions even though level 2 only has 14 new formulas. I will take formulas from level 1. You don’t know what formula I will be taking. There is a review and test this week. Make sure you are successful on the review before you take the test. If you are not successful please get some help from me or someone else. I will have the videos up soon for the lessons. Let me know if you have any questions!
