Proportional Reasoning


September 23-24, 2015

8:30 a.m. – 4:30 p.m.




Eligible Attendees

Initial registration is limited to two participants from each TRC Math Collaborative. The individual attending the PDA should plan to be the primary presenter for a minimum of two-day turnaround training that is both pedagogy and content intensive. If your attendee is not qualified in both roles, please consider recruiting an additional individual after the PDA to meet the content expertise requirements for the turnaround training. Total number of participants is limited to 50. Please email Debbie Plowman Junk at to be placed on the waiting list before registering more than two individuals.



Dr. Olof Steinthorsdottir, from the University of Northern Iowa will be leading this PDA. Olly has two interrelated research emphases, gender equity in mathematics education and teaching and learning for understanding within the domain of whole numbers and rational numbers in Preschool through Middle School. Olly has also been a Cognitively Guided Instruction teacher leader for a number of years and understands the important role that good instructional tasks and knowledge of strategies children use as they solve these tasks play in good instruction.

The Proportional Reasoning in the Middle Grades PDA is 2-day course in which proportional reasoning is addressed through missing value problems. This PDA will feature possible learning trajectories which help teachers recognize, develop and present good tasks and task sequences involving proportions during instruction. Participants will also learn about the strategies students use when they are solving these missing value problems.



PDF Downloadable Agenda available in PDF format.
