Kids can be difficult to organise, especially when they're bored. Keep them busy with "I'm Done" sticks.
Essentially, you write out a bunch of activities on ice block sticks, and when your kids come to you complaining that they're bored, send them to the jar of activity sticks. This way, they have plenty of options to keep themselves entertained — and you can focus on what you need to do around the house.
You can apply this technique to kids of many ages. You can create a separate set of sticks for each child, or do a fun set and a productive set (things like practice your multiplication tables, etc). For more info on "I'm Done" sticks and how they can be used, check out the full post linked below.
