Preventing Mathematics Difficulties in the Primary Grades: The Critical Features of Instruction in Textbooks as Part of the Equation

High-quality core instruction in kindergarten and first and second grade is critical to prevent mathematics difficulties. Evidence-based critical features of instruction should be part of core instruction and be included in mathematics textbooks. This study examined lessons from kindergarten and first- and second-grade basal mathematics textbooks to determine the extent to which 11 critical features of instruction were present. Overall, results showed an “Approaching Acceptable” rating, meaning that the features were not fully incorporated. Implications include the need for textbook adoption committees to be mindful of the importance of including effective instructional practices when making textbook decisions and for teachers to scrutinize the components of lessons to determine if these features of effective instruction are included.
