UNSPSC 60104602: Gravity models or model sets

UNSPSC 60104602 Gravity models or model sets (Commodity) covers educational models and manipulatives—including Montessori math and science materials, classroom demonstration apparatus, and hands-on STEM kits—that state and local school districts procure to support curriculum delivery and student engagement. Recent activity shows the code tagged to broader educational-materials solicitations; concrete buying includes Montessori classroom packages with math manipulatives, task cards, and nomenclature materials, as well as comprehensive STEM and college-readiness kits with embedded physics and science modeling components. Issuing bodies are predominantly school districts, both large incumbent purchasers and smaller systems participating in cooperative consortia. Hillsborough County Public Schools in Florida appears as a repeat buyer across multiple solicitations within a four-month window (February through April 2026), while Cartwright Elementary School District No. 83 in Arizona coordinated a multi-jurisdiction procurement through the SAVE cooperative purchasing vehicle.

Recent opportunities cluster in Arizona and Florida. Cartwright Elementary School District No. 83, on behalf of SAVE, issued an RFP (RFP260331) posted May 21, 2026, due June 8, 2026, for STEM and College & Career Readiness Kits, Programs & Materials supporting multiple Arizona school districts, municipalities, counties, and higher education institutions, with estimated annual consortium usage of $1.346 million and individual district buys ranging from $10,000 to $350,000. Hillsborough County Public Schools in Florida solicited Montessori Classroom Supplies via ITQ 26126ITQEST (posted April 13, 2026, due April 10, 2026) covering 310 line items including geography materials, math manipulatives, and science research resources with a 15 percent markup cap, and earlier issued an ITB 26067ITBEST (posted February 18, 2026, due March 23, 2026) for catalog-discount pricing on Montessori materials available to other public agencies within Hillsborough County. Prices in both formats remained firm for one-year minimums with multi-year renewal options contingent on performance and appropriations.
