Ask HN: Sources for recreational math for kids?

What are good sources for recreational math for elementary school kids? I have a great collection of recreational math books, but my kids are younger so I prefer video at this stage and challenges that don't require too much knowledge but rather focus on logic, number senses, shapes, spatial cognition and so on.

For example, riddles about finding fake coins using scales seem to work well.

Your kids might like computer science unplugged activities, they're hands on (no computer required) and can dovetail into some fun CS programming projects down the road:

Two nice resources, though not recreational in the way I had in mind, are The Number Race and The Number Catcher.

Beyond the skills I had in mind, but this is a cool idea - wish I had this when I was first learning about these functions.
