With thousands of you getting new mobiles and MP3 players for Christmas it's important to know how to keep you and your property safe.
Street crime is higher in January, so to stop children becoming victims, the government has come up with a series of lessons in personal safety.
The lesson packs will be sent to 600 schools across England and Wales.
The assemblies and classes for 10-14 year olds will concentrate on personal safety and street crime.

"It's important to help young people avoid becoming victims of robbery and to deter potential offenders," the boxer added.
Andrew, 14, who attended the assembly, says he does worry about crime and thinks the lessons are a good idea as "a little extra help doesn't hurt".
Dominic thinks children are naive
But Dominic, 13, said: "Some kids act naive and walk around with their valuables like their mobile phones and chains hanging out."
Fall in street crime
The lessons will begin on Monday, 10 January, as part of SAFE week which runs until 14 January and will involve workshops designed by teachers, police and experts from crimestoppers.
Street crime has fallen dramatically since 1997 and it's hoped the lessons will reduce it even further.
