Traver Road staff say PLCs, 15-day challenge lifted first-grade math mastery from 49% to 78%
Summary
Traver Road teachers described work with professional learning communities (PLCs) and the Solutions Tree 15-day challenge; first-grade team reported a rise from 49% to 78% mastery on a targeted addition/subtraction standard after one PLC cycle.
Traver Road teachers told the Arlington Central School District Board that structured professional learning community (PLC) work and a Solutions Tree 15-day instructional cycle have produced measurable short-term gains in first-grade math.
Traver staff presented examples of school-level PLC activities, including a collective "shipwreck" problem and a "compass point" exercise to help teams identify working styles and norms. They said PLC teams select an essential standard, unpack learning targets, create common formative assessments (CFAs) and then regroup students for targeted intervention or enrichment during an intervention/enrichment block.
The presenter described first-grade results after one 15-day PLC cycle: "When we gave our pre assessment out of our student population, 49 percent of students had showed that they were able to add and subtract to 10 with accuracy. And then after only 1 PLC cycle ... that lifted to 78 percent," the presenter said. Teachers credited shared planning, common assessments and rotating students into targeted instructional groups for the rapid gains.
Traver first-grade teacher Kim Van Voorhis joined the presentation and explained how teams used learning ladders, proficiency scales and shared assessments to place students in targeted groups and then reassess. Staff also reported benefits beyond academics: students met peers from other classes and teachers reported stronger grade-level collaboration and increased willingness among staff to ask "why" and push back for clarity during planning.
Board members asked about the source of training and the definition of mastery. Traver staff said initial training and the 15-day framework came from Solutions Tree and related coaching; mastery was described as alignment with New York State standards for the identified essential learning targets and measured via the common formative assessments the PLC created.
Traver staff said they will continue cycles of assessment and regrouping and that early results are encouraging but still part of an iterative process.
