Large numbers of students are not proficient in mathematics and there are disparities in mathematics achievement between students from different ethnic and socioeconomic groups. Mathematics skills are important for both academic and workplace success and there are a large number of interventions that aim to improve student mathematics achievement. This review focuses on mathematics interventions that are typically used in kindergarten through grade 8 and are designed to affect students’ mathematics achievement.
Whether an intervention falls under the scope of this review depends on both the grade level and content of the intervention. For example, the review can include students in grades 9–12 if they use a primary mathematics intervention such as pre-algebra.
The following research questions guide this review:
- Which interventions are effective at increasing the learning of primary mathematics content and skills
- Are some primary mathematics interventions more effective for certain types of students, particularly students who are at risk of failure in mathematics?
