### Engaging Math Activities for the Summer Break

Below is a growing collection of resources I designate as "Summer Math Activities". These deal with various (mostly non-computational) aspects of early mathematics and are suitable for young children. There is no good reason not to try these activities at any other time of the year. During summertime, with the kids out of school or kindergarten, it may be more urgent to occupy them in a meaningful way.
