Wow way off marj there easty.
Education is not only math..english...mandarin and history....
What makes a man a man is his academic education but aso his life experiences. Summer holidays are abt this. Giving time to students/kids to do /experience other things.
Now if parents aspend their time letting kids play videos games instead of doing more meaningful things....it's not the teachers fault...teachers don't replace parents...
If u feel that the above can only work w $ (poor parents don't have the $ to give their kids such experiences) then whar should be set up is more 'free' or heavily subsidized summer initiative programs that would give an opportunity to these kids to do/see somethibg else.....not more math..english etcetc
