The Manor Park pupil, who’s seven years old, is currently being educuated at home while the schools are closed.
Every week teachers send out work and challenges for pupils to complete during the week.
Ruben’s challenge for the week was to write a letter to the Queen inviting her for tea.
Mum Claire McCabe said: ’This challenge was something that he really enjoyed doing, he would one day like to visit Buckingham Palace to see where she lives.
’Ruben really does believe the Queen is going to come for tea one day.’
Another challenge was to draw a picture of Buckingham Palace and describe it in a few words, which Ruben did as well.
As part of his daily exercise, Ruben walked to the post office to send the invitation to the Queen, who celebrated her 94th birthday this week.
