District to post Illustrative Mathematics 360 for review as state shifts toward integrated math

The Queen Anne’s County Board of Education heard on June 17 from Becky Burridge, the district’s K–12 math supervisor, about Maryland’s shift toward yearlong integrated Algebra 1 and Algebra 2 and the district’s plan to post Illustrative Mathematics 360 for public review as a bridging curriculum.

Burridge said the state adopted a new math policy in June 2025 that will move many districts toward a four-domain, preK-through-integrated-algebra approach. "When integrated comes in, it kind of it replaces algebra 1 the first year," she said, explaining how the transition will be phased so students already in the traditional algebra/geometry sequence can finish that pathway without disruption. Burridge described teacher surveys, vendor vetting and the district’s decision to prepare IM360 materials for a six-week review period and to bring a recommended adoption to the board in August.

She emphasized that IM360 is an open-source nonprofit curriculum used by multiple vendors and that the district has already developed quarterly assessments, finals and pacing guides aligned to the resource. Burridge and department leads noted that state testing and platform rollouts still leave some scheduling questions: the state’s earlier 2027–28 implementation window may shift and the district is prepared to use IM360 as a traditional A–G–A (algebra/geometry/algebra 2) resource in the near term and switch to integrated alignments when state guidance is finalized.

What’s next: Materials will be posted to the district website for review, and the board is expected to consider formal adoption at an August meeting. District staff said they are continuing to work with high-school departments and principals to plan course sequencing and professional learning.
