The Jeffco school board unanimously approved a $4.3 million purchase of the Math Expressions curriculum for next school year at its May 1 meeting.
Math Expressions will replace Math Investigations, the math curriculum Jeffco had used for the last nine years.
A panel of 10 district employees gave a presentation on Math Expressions before the board took a vote. District staff said the new curriculum aligns with new Colorado academic standards and that Investigations has run its course in the district.
The curriculum, which will serve kindergarten through sixth grade, will include a textbook and workbook for each student.
One of the school board’s goals for the district is to have the percentage of fourth-graders who score advanced and proficient on state tests jump from 77 percent to 80 percent.
Math Expressions is currently being used by Boulder County Schools.
