Hundred Board Logic Problems

These original Mathwire Hundred Board Logic problems are designed to help students use a hundred board to solve problems.  Students read each clue, then eliminate numbers on the hundred board that do not fit the clue.  After reading through all clues, students should be left with only one solution.  They should check their solution by rereading each clue to be sure their solution fits.  These problems were field-tested in Grades 3-8 classrooms and students loved the experience because the step-by-step process enabled them to be successful at solving these problems.

Enrichment:  After students have solved several of these problems, they may be challenged to create their own original problems.  Provide blank 100 board and logic problem templates.  Students should start by circling their target solution.  They then write clues that will eliminate all other numbers.  Finally, students should exchange problems and use peer review to edit their problems, clarifying and modifying clues to eliminate any confusion.

Creating original problems is a higher-order thinking skill (Synthesis on Bloom's Taxonomy) that extends students' problem solving ability and requires flexible thinking about mathematical concepts, skills and vocabulary terms.  Student-created problems may be added to the classroom math center and used on game days as a problem-solving center.  Additionally, these problems may be used in the initial lesson in subsequent years.  Consider publishing the problems with the author's name and copyright year.  Students love seeing their names in print!

1. I have just discovered your website and blog and I am hooked!!! I stumbled across this gem when I was searching for the directions for the Everyday Math Number Grid game my daughter played in first grade this past year. You have a link to it on your site but the site it links to is no longer active. Is there any way you could pass these directions along?
