If you and your kids are LEGO fans, you probably have a lot of completed sets around the house. But if you're moving to a new home, there are certain steps that need to be taken in order for these to be transported safely. This article covers the best way to pack legos for moving, as well as how to properly disassemble them.
First, sort through the collection and make sure that you have a complete inventory of the pieces you own (or let your kids do this). This will help you to find all the LEGO that needs to be packed up, including the ones that are in unopened boxes, partially-built items, random bins/bowls/trays of loose bricks, or any other groupings that have been scattered throughout your home. Try to keep similar LEGO groups together if you can, and label any bags that have specific sets or builds in them - this will reduce confusion in the future when you need to retrieve them.
Then, dust any assembled LEGO sets that you have. This is especially important if they've been sitting on the shelves for a while. This will decrease the likelihood of damage during the move.
If you don't plan to reassemble a particular set, then it is better to donate it instead of letting it go to waste. Many local kindergartens, child care centers, elementary schools, and charitable organizations will take old LEGO that is in good condition.
