K Kids is the elementary branch of the Kiwanis Club of Elizabethton, an organization of Kiwanis International. The club does various service projects throughout the year to benefit children and families at East Side and in the Community. In the 2016-17 school year, these projects included the Hearts for the House (Ronald McDonald House), beautification projects at the school and at the home of retired ESE principal Dr. Josh Wandell, and thank you cards written to veterans at the Veterans Administration Nursing Home. The club is open to students in grades 4 and 5, and the students are chosen through teacher recommendations. It meets at East Side on the first Thursday of each month.
