Give them a challenge to complete: Some ideas include learning to create something out of origami, creating a photo book for a family member, or doing a jigsaw puzzle. Once your date is over, you can either help them complete the task or have them teach you how they did it.
Put their planning skills to work: Have them plan their dream family vacation with details of how you would travel, where you would stay, what you would do, etc. The next day, invite each of your kids to share their presentation for their dream family vacation and explain why it would be special to them. If they aren’t into traveling, have them design their dream bedroom, explore their dream career, or investigate something else that fits their interests.
