Today we go back to the blackboard to chalk up memories of lessons from the past.
Among the photos featured is a shot of German students at Brierton Comprehensive during an exchange visit in the 1980s.
A photo taken at Lynnfield School in around 1953 is also shown, together with a sporty one from West Hartlepool Secondary Technical School in 1949.
“The Tech’s football team won the Schools Senior League Shield and Cup in 1948-49,” said Mail archivist Susan Swinney.
Our final photo today shows a student examining a skull at a Hartlepool school in the 1950s - but mystery surrounds which school.
“I discovered this rather gruesome shot among our plate glass negatives. Can anyone help solve the puzzle?” said Susan.
