Investigations in Number, Data, and Space®

This highly-acclaimed curriculum, developed in partnership with classroom teachers, provides a complete mathematics program for grades K-5. Activity-based investigations encourage students to think creatively, develop their own problem-solving strategies, and work cooperatively. Students write, draw, and talk about math as well as use manipulatives, calculators, and computers. Mathematics content includes the number system; addition, subtraction, multiplication, and division; collecting, sorting, and representing data; probability and statistics; measurement; changes over time; 2-D and 3-D geometry; fractions; computation and estimation strategies; and tables and graphs. Assessment is embedded within the investigations.

Investigations is infused with teachers' practical suggestions and strategies, including actual student dialogues, lesson plans, teacher notes, and reproducible student materials.

TERC also provides professional development and support through Investigations Workshops.
