Historically, when Florida school districts reevaluate which math instructional materials they will use, they have had more than one publisher to choose from.

Now, the only publisher approved by Gov. Ron DeSantis and the Florida Department of Education for K-5 mathematics is Accelerate Learning, a company out of Houston, Texas.

“In the subject area as large as mathematics for grades K through five, it is unusual for there only to be one publisher to choose from,” said Billy Epting, assistant superintendent for academic services for Leon County Schools.

The Florida DOE rejected more than 50 mathematics textbooks — about 40% of those submitted — for failing to meet Florida’s new learning standards or because they “contained prohibited topics” that included references to critical race theory.

For regular math classes, Accelerate Learning’s STEMscopes Florida Math books are the only option for school districts.

There are two more publisher options for accelerated math, McGraw Hill LLC and Savvas Learning Company LLC, formerly known as Pearson K12 Learning LLC.

DOE said more than half the textbooks being disallowed incorporated “prohibited topics or unsolicited strategies, including CRT,” while others were not allowed because publishers “rebranded” Common Core Standards.

According to the Accelerate Learning’s website, the math book for Florida was “built from the ground up to the Florida B.E.S.T. by practicing educators using the flexible 5E lesson model.”

The K-5 math books were also created in partnership with Rice University.

DeSantis has taken a lead role nationally in Republican efforts to aggressively push back against liberal cultural values and what he calls “woke indoctrination.”

A measure labeled “Individual Freedom,” also known as the “Stop WOKE Act,” was passed during this year’s legislative session and still waits for the governor’s signature.

The legislation (HB 7) prohibits any teaching that could make students feel they bear personal responsibility for historic wrongs because of their race, color, sex or national origin.
