The pack, called "What's going down?", is being sent to head teachers at primary and secondary schools throughout the UK.
The content has been developed to engage teachers, pupils and parents to help achieve the campaign's objective of ensuring a million more children in England are eating school lunches by 2010.
The pack includes lesson plans, activity sheets, hand-out stimulus and interactive whiteboard activities, supported by a teacher-targeted microsite and a national pupil competition.
All of the resources have been mapped to specific areas of the National Curriculum to support teachers in the delivery of their subjects.
Wendy Culley, group account director at Spinnaker, said: "'What's going down?' is a campaign designed to engage students with its fun and inspiring content whilst also being relevant to teachers thanks to its curriculum links.
"We are looking forward to its positive contribution towards increasing the uptake of school meals."
The School Food Trust was established by the Department for Children, Schools and Families to promote the uptake of school meals. It is spearheading the "million meals" campaign, which launched in October 2007.
