"Not only does 12 + 1 = 11 + 2, but the letters "twelve plus one" rearrange to give you "eleven plus two." – Neil deGrasse Tyson

Barnesville's MATH instruction is focused on helping each child reach their full potential.

The Barnesville School’s mathematics program strives to promote meaningful learning for all students through a comprehensive curriculum. Students are engaged in the process of making sense of mathematics, developing conceptual understanding of mathematical concepts, and applying strategies for solving meaningful problems.


In our Preschool mathematics program we believe young children learn best by exploring. The approach of the program is hands-on and experiential, encouraging discovery and application of mathematical concepts to everyday life. Children develop number concepts through counting skills, numerical recognition, and one-to-one correspondence. They learn to sort and classify and to identify, create, and extend patterns.

Lower School

Barnesville uses the Houghton Mifflin Harcourt Go Math Curriculum, which focuses equally on understanding, procedural skills, and mathematical fluency. Students practice skills using manipulatives and multiple models to move through a carefully-sequenced arc of learning, developing problem-solving strategies and becoming critical thinkers. Students are assessed and then grouped according to skill level. Small group instruction allows teachers to accommodate each student’s individual learning styles.

Middle School

The Middle School mathematics curriculum is designed to continue students’ development of mathematical fluency, problem-solving skills, mathematical reasoning, and ability to communicate mathematically. The goal is for students to leave the eighth grade with a strong algebraic foundation. The mathematics program strives to provide a challenging and comprehensive program, structured to the abilities and needs of all students in the Middle School. Early testing, ongoing assessments, differentiated instruction and teacher observations all serve to provide suitable placement of students.
