Problem of the Week

Each week, I post the University of Waterloo Problem of the Week for my students.  My students are currently grades 6 and 7, but some are modified all the way back to grade 3.  I post three different levels, the grade 3/4, the grade 5/6, and the grade 7/8.  Students may choose any of the problems to solve.  Sometimes they pick problems that are too easy, but occasionally they will pick a problem that is too hard.  In our problem of the week corner, there are white boards to use for solving and graph paper and manipulatives are also available nearby.
