Tailoring Math Instruction to Individual Student Needs


One of the best-performing school systems in Maryland, Carroll County Public Schools, consistently ranks in the state’s top tier for elementary mathematics.

Donn Hicks, supervisor of elementary mathematics for the district, leads a team of 12 math resource teachers who support teachers and students in 23 elementary schools. In 2009, they adopted DreamBox Learning Math to differentiate instruction with meaningful, independent learning activities.


Help a broad range of students develop number sense

Elementary school teachers often struggle to help students develop number sense, and many lack time or pedagogical experience to tailor mathematics instruction to individual student needs. Carroll County math resource teachers were looking for a web-based program that would help students develop number sense and build a foundation for mathematics fluency.

“We were discouraged by most of what was out there. It was drill and practice,” says Laura Hunovice, mathematics resource teacher for Hampstead and Linton Springs elementary schools. “Struggling students don’t need more of the same — they need a different approach.” In addition, students ready to work beyond their grade level need to build on concepts they understand, not review them.


Build conceptual understanding with virtual manipulatives

“DreamBox Learning provides a seamless connection between what students are doing in class and their independent study. DreamBox knows what concepts the student understands, and offers appropriate, meaningful learning activities each time he or she logs in.”

— Donn Hicks Supervisor, Elementary Mathematics

DreamBox Learning combines a robust mathematics program, based on Common Core State Standards, with an adaptive engine that presents students with appropriate activities based on demonstrated understanding of concepts. By integrating assessment and instruction, DreamBox Learning engages all students in their optimal learning zone.

The visual models and scaffolding built into DreamBox Learning help all students develop foundational math skills.

Virtual manipulatives help to deepen students’ conceptual understanding. DreamBox complements classroom instruction with tenframes, mathracks, number lines, and other manipulatives just like the ones students use in class. Carroll County teachers reported that students who were reluctant to use manipulatives in class were eager to use them in DreamBox, and their attitudes about using the physical manipulatives during lessons improved.

Developing computational fluency requires a balance and connection between conceptual understanding and computational proficiency. DreamBox presents students with appropriate activities based on demonstrated understanding of concepts. “With DreamBox, students are not relying on a set of procedures,” says Hunovice, “but on an understanding of why these strategies work.”

Finally, students put these strategies and mental models to use in problem-solving activities that let them informally explore concepts. DreamBox Learning also helps primary teachers who may not have a math specialty prepare for the future. “I see a higher level of rigor coming with the Common Core State Standards,” says Hunovice. “For primary teachers, DreamBox is a nice bridge for where we are right now and where we need to go.”


From intervention to enrichment

Enthusiasm among students and their teachers encouraged Carroll County to expand DreamBox Learning from a pilot program used in select schools to one used in all 23 elementary schools, and from intervention for students below grade level to enrichment for all students. Teachers feel confident that students working independently on DreamBox are benefiting from highly individualized instruction at an appropriate level.

At budget time, Hicks asked teachers how they should allocate limited resources. Many decided to purchase DreamBox Learning licenses as opposed to spending money on consumable textbooks with tear-out worksheet pages.


Individualized support for high-performing and struggling students

Donn Hicks and his team selected DreamBox Learning to help teachers and students continue to excel in mathematics. With DreamBox Learning as a resource available to teachers to supplement the curriculum in every Carroll County elementary school, Hicks reports that “our high-performing students are using the program to further strengthen their number sense comprehension while others, who may be below grade level, have benefited from spending extra time working on foundational basics. For both sets of students, the blend of classroom instruction and DreamBox Learning has been a big win.”

Fayette County Doubles Growth on the Renaissance Star Math®

The scaled score growth from Fall 2016 to Spring 2017 of students in Grades 1–7 who completed at least five DreamBox lessons per week was 97 percent higher than the STAR growth of student who didn’t use DreamBox. Furthermore, approximately 80 percent of Fayette County’s K–5 math teachers are now fully and consistently on board with small group instruction and DreamBox. Most educators confidently engage in routine, small group models using DreamBox as a key part of their rotation.

Driving Personalized Math Instruction in a Title I Focus School

In 2016, Westport achieved a 98 percent growth in student standards on DreamBox. In September 2016, 56 percent of students were working on first grade standards, and by October, 10 percent of that group had moved up to second grade standards. “Immediately we started seeing change,” says Dorsey. By the end of the year in May, only 5 percent of the population were still working on kindergarten standards. The school’s proficiency on an external District Standardized Assessment increased by 36 percent, the largest amount in several years. As Dorsey says, “We know that DreamBox is helping us bridge the gap to make significant growth for students.” Dorsey indicates, not only does it bridge the gap, but also assists with grade level expectations and growth.
