The textbook is titled Social Studies Alive. Parents who want the book removed from the curriculum say portions of the text are not objective, teaching instead in an ideological manner on subjects such as public education and health care.
The issue first surfaced back in May when Frederick County resident Cindy Rose filed a formal complaint with the board after her 9-year-old daughter began discussing the book at home with her.
Although the text is not the only book available in the system for third-grade studies, critics say there's no guarantee it won't be used.
School staff defended the book, and at first the board agreed, but later asked the matter be examined during a full board meeting. The full board meeting is Wednesday afternoon at school board headquarters in Frederick.
