Sixth-graders Kelsey Gallotte, left, and Ryan Flores eat lunch together Friday, which was a transition day for sixth-graders at Southern Hills Middle School. Boulder Valley officials are trying to erase the socio-economic lines created when children who get free and reduced-price meals buy hot lunches and affluent children opt to buy a-la-carte items — such as animal crackers, chips and juices. The district is blending the hot lunch and a-la-carte lines and eliminating some of the single-sold items.
