Bluffton University will offer two mathematics workshops Aug. 9-11 for middle and high school math teachers and intervention specialists.

Aug. 1 is the registration deadline for both "Become a Master Teacher in Middle School Probability and Statistics Topics," taught by Marilyn Link, a retired teacher from Coldwater, and "Using Rich Problems to Learn and to Teach Good High School Mathematics, Course 2." That course, which differs from last year's similarly named workshop, will be taught by Duane Bollenbacher, an adjunct faculty member at Bluffton.

Workshop hours are 8:30 a.m. to 4:30 p.m. daily. Each may be taken for 22.5 contact hours of Local Professional Development Committee credit, at a cost of $125, or, on a pass/fail basis, for one semester hour of graduate workshop credit, for $275. Lunches are included; other meals and housing are available.

For more information, contact Bollenbacher at 419-358-3296 (work), 419-358-7365 (home) or at [email protected].
