Mrs. Sackman teaches 6 grade math and science. She loves teaching middle level students and recognizes that at their age, there is so much more learning to do than just academics.

Mrs. Sackman has lived many places, she was born in Ohio, grew up and attended college in Michigan, and lived in Boston, Georgia, Argentina, and Wisconsin as an adult, all of which contributed to her love of learning and working with people from all different walks of life. She is married and has two amazing daughters, one living her dream in Denver, working in an elementary school and the other a percussionist with the US Air Force Band. Although she is officially an empty nester, Mrs. Sackman still has a very loved Cockapoo, Ruby, at home. Her passions are traveling, cooking, gardening, and learning. She loves coming to work at Kaleidoscope Academy each day, interacting and learning with the fabulous students who choose us as their school.
