Title:  Investigations in Number, Data, and Space
Description: Investigations in Number, Data, and Space is an activity-based K-5 math curriculum designed to help students understand number and operations, geometry, data, measurement, and early algebra. The WWC identified 46 studies that examined the effects of Investigations in Number, Data, and Space on the mathematics achievement of elementary school students. One study meets WWC evidence standards without reservations, and one study meets standards with reservations. Both studies are randomized controlled trials and include more than 8,000 students in grades 1-2 and grades 4-5 in 16 districts across 13 states. Based on the evidence presented in these two studies, the WWC found Investigations in Number, Data, and Space to have potentially positive effects on mathematics achievement for elementary school students.
