Investigations in Number, Data, and Space®
Elementary School Mathematics

Investigations in Number, Data, and Space® was found to have potentially positive effects on mathematics achievement for elementary school students.

Investigations in Number, Data, and Space is an activity-based, K–5 mathematics curriculum designed to help students understand number and operations, geometry, data, measurement, and early algebra. Each instructional unit focuses on a particular content area and lasts for 2–5.5 weeks. The curriculum encourages students to develop their own strategies for solving problems and engage in discussion about their reasoning and ideas. The lessons are activity-based in order to facilitate increased comprehension of basic math fundamentals. The curriculum is presented through a series of resource books called ”curriculum units” that provide teachers with guidance on implementation. One or more of the units for each year has a software program associated with it. Other materials include manipulatives, flash cards, overheads, and textbooks.
