Waggener Edstrom handled the account previously, with Bite being appointed in a non-competitive pitch.
The agency will work with Casio to produce research into the use of technology such as graphic calculators within the classroom and explore whether this could be key to improving UK skill gaps in core subjects such as maths.
Rachel Gilley (pictured), deputy managing director UK at Bite, said: "Casio is quite simply one of the most exciting tech manufacturers in the world. This is a company with incredible heritage and we’re excited about our work together to reach such a specialist and important target audience. We pride ourselves at Bite in creating tailored and targeted campaigns and we anticipate that our work with Casio will be one of our most exciting campaigns yet."
Tim Gould, head of marketing for Casio UK, added: "Casio is proud to support maths teachers and we hope that our work with Bite in this area will help uncover new ideas around the use of technology in classrooms. We chose to partner with Bite due to its experience in delivering insightful and exciting campaigns."
Casio is the latest win for Bite, following its appointment by WeWork and BloomReach in recent months.
Casio was founded in 1946 and released the world’s first entirely electric compact calculator in 1957. The company has partnered with the Mathematics in Education and Industry group, and is the main sponsor of the organisation’s annual conference.
