In order to be classified as evidence-based, an instructional program or practices must be tested and have a record of success. Reading Manipulatives products have been created by teachers, tested over many years, and they meet NCLB standards. Students who used them have made remarkable progress, developed self-esteem, improved their organization and accountability, and cultivated a greater enjoyment of reading and writing. The following characteristics, which are predicated by findings of educational and brain research, are fundamental design and content principles of the manipulatives.

Experiential and engaging
American children and adults of today are action-oriented; consequently, tactile modalities are now dominant for all ages, not just children. Data from millions of Myers-Briggs style tests shows that 70 percent of Americans are sensing types who learn best with hands-on, experiential materials that proceed in a step-to-step manner. For this reason, manipulatives that build literacy skills are extremely effective and result in students staying on task.

Challenging and multilevel
For many students, removing written responses reduces risk and stress, which often cause diminished performance. Studies confirm that an atmosphere combining low threat with significant challenge is most conducive to learning, making multilevel materials optimal. Grade-level designations are not attached to Reading Manipulatives products because students should be offered whatever they are capable of accomplishing.

Natural
Manipulatives utilize natural approaches for developing many reading skills, such as sequencing or blending. Since activities are intuitive, cumbersome directions are eliminated.

Holistic
Fragmented instruction inhibits learning, and this is the major problem with workbooks and worksheets. Reading Manipulatives products employ holistic methodology, covering the entire scope of each literacy skill. Additionally, the plentiful practice leads to mastery.

Student-centered
A lab-like setting where students have choices is remarkably effective. Active involvement builds accountability. Once students are taught the skills and introduced to the sets of manipulatives, in most cases they are able to select, complete, correct, and record activities. They are highly motivated to work through the sets and achieve superior results. The visible nature of manipulatives encourages interaction. Students naturally assist one another. Tutors have greater confidence as they learn about the skills and their students. Opportunities for expanding language abound.
