Blue Day was marked at Cumberland Infant School with staff and pupils wearing blue.
The children donned Pompey kits, blue dresses, and even a Thomas the Tank Engine t-shirt.
Everyone brought in a donation and the school managed to raise £160.
Headteacher Beverly Naylor said: ‘Tom Prince was a local boy and one of the teachers here knows the family, so it’s a really good local charity to support.
‘The kids really enjoy coming dressed up and I think they like getting involved in the community aspect.
‘They were very excited in assembly this morning to see what everyone was wearing.’
