Answer:
Im with the person that answered parental controls and Smart boards
Explanation:
1) in my opinion parents can go above and beyond with parental controls yes its good to protect your kids but let them have freedom if they feel they shouldn't see or read that then they wont also i think you should teach your kids to not look at bad things so you don't have to go the extra mile with setting them up
2) smart boards just cause they always seem to break and then they aren't that smart and they cost a lot of money to fix that could go to better school lunches
