This book contains over 100 classroom-tested projects and ideas taken directly from the pages of 'The Math Projects Journal', a periodical that for over six years has shared these one-of-a-kind lessons with teachers around the world. "MPJ's Ultimate Math Lessons" offers you 80 innovative lessons and activities that can be immediately implemented in your classroom. Most of these lessons have an accompanying student handout that may be photocopied for use in your classes. To avoid reducing these unique lessons to mere worksheet exercises, the book provides 27 thought-provoking articles that will assist you in incorporating math projects in your daily routines and that will challenge the very way in which you think about math education. The lessons in this book have proven to help teachers increase student understanding of mathematics and, in turn, raise student achievement on standardised tests.
