Elementary and middle school students across Montgomery County will encounter a revamped math curriculum when MCPS classes begin Tuesday, Aug. 25, part of a statewide overhaul aimed at reversing years of declining scores.

Maryland's updated math standards narrow the scope of what students must learn at each grade level, giving teachers more time to reinforce core concepts and build fluency. The changes affect elementary and middle grades only; high school students won't see adjustments yet.

The urgency is clear. Only 27.1% of Maryland students demonstrated math proficiency on the state's MCAP assessment in spring 2026, according to results released July 28. Among eighth graders statewide, just 9.6% were proficient. MCPS students scored above those statewide averages with what Superintendent Thomas Taylor called "clear and steady improvement," WTOP reported.

The new standards replace Maryland's 2012 Common Core math framework. Educators concluded that the old approach often introduced concepts once without reinforcing them in later grades, leaving struggling students further behind. Under the revised framework, some topics shift to different grade levels, and early grades place heavy emphasis on math fluency: memorizing addition, subtraction, multiplication and division facts.

"We are not focused on the memorization but understanding the strategy of how to answer the question," Karen McKiernan, a Montgomery County fifth-grade math teacher entering her 31st year, told The Baltimore Banner. McKiernan said much of her classroom time will go toward training students how to read a problem, identify what it asks and choose a solving strategy.

Students will still be expected to explain their reasoning, not just produce a correct answer. That hallmark of Common Core-era instruction remains intact.

Assistant state superintendent for instructional programs Elise Brown said the updated standards provide more clarity and coherence from grade level to grade level without a wholesale overhaul. The state has also hired math coaches in 14 schools across four districts to support teachers, with plans to expand the program in the 2027-2028 school year. Whether any of those 14 schools are in Montgomery County has not been confirmed.

What Potomac parents can do

The Maryland State Department of Education published family guides at marylandpublicschools.org with grade-level activities parents can use to reinforce lessons at home. The state held information meetings during summer 2026, drawing about 1,000 families statewide.

Maryland will also retire the MCAP in favor of a new test, the Maryland System of Testing Academic Readiness, for grades 3-8 starting in spring 2027. The new assessment will align with the updated standards.

The next MCPS Board of Education business meeting is Sept. 24 at 4 p.m., though no math curriculum agenda item has been confirmed for that date.
