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.
