The Brain Teasers feature on Kids' Place Houghton Mifflin Mathematics provides math puzzles for each
chapter in the Houghton Mifflin Mathematics textbook. You may have your students read the
Brain Teasers online, or you may prefer to print, photocopy, and distribute the pages.
Each online Brain Teaser includes a Question page, a Hints page, and a Solution page. The Solution includes the answer and an explanation of the reasoning used to solve the problem. If you distribute printouts of the pages, consider giving out only the Question and Hints pages, and then divulge the Solution after students have had time to solve the problem on their own.
Though not correlated to Houghton Mifflin Mathematics, our regular Kids' Place Brain Teasers provide additional math puzzles throughout the year. Each week, a new Brain Teaser is posted at each of three grade ranges: 34, 56, and 78. The solution is posted the following week. Use these puzzles for extra credit or as additional challenges.
