It is not a part of the curriculum until Algebra 2 (after algebra 1, and geometry). So typically students will not see matrices until grades 9-11. Matrices are taught to all students at that time. BUT we teach a limited number of skills. So students learned how to add/subtract and multiply by hand. We taught how to find the determinant and the inverse by hand - but only with 2x2 matrices. All the rest of the skills were practiced using a TI 83/84 calculator. We did not teach cramer's rule, or augmented matrices or gaussian this year.Algebra's Friendhttps://www.blogger.com/profile/04729315514507170702noreply@blogger.comtag:blogger.com,1999:blog-8399389267815059112.post-87860975925343661002013-10-20T09:07:23.532-05:002013-10-20T09:07:23.532-05:00This comment has been removed by the author.Algebra's Friendhttps://www.blogger.com/profile/04729315514507170702noreply@blogger.comtag:blogger.com,1999:blog-8399389267815059112.post-28361549053159699472013-10-19T22:33:41.254-05:002013-10-19T22:33:41.254-05:00Thanks for sharing, sounds fun.

At what age do you teach matrices, and is it taught to all pupils?Cavhttps://www.blogger.com/profile/08497166692282461180noreply@blogger.com
