I've seen it more profoundly in children with learning challenges. Research has shown that summer learning loss occurs when children don't have access to camps, recreation and other summer activities.
During the school year, students learn at relatively similar rates. More than 1/2 of the achievement gaps that occur over summer break can be attributed to unequal access to educational (and fun) activities due to economics, disability or traveling distance.
We as parents and educators, can prevent summer learning loss, by exposing kids to a variety of fun, interactive enrichment activities over the summer:
Outdoor activities (plant a garden, go fishing, playground, etc.)
Play group activities
