Following the Montessori math curriculum, students move from concrete to abstract mathematical operations during their Upper Elementary years. In addition to Montessori math manipulatives, they work with complementary workbooks and curricular materials that reinforce specific math concepts and skills. Students meet with teachers in small skills-based groups throughout the week to receive direct instruction. As they progress through the curriculum, gain momentum, and make developmental strides, we help them build the critical skills and strategies of mathematical problem-solving. This further supports students as they prepare for the rigors of the Middle School mathematics program.
