Reviewed for First Grade, 2010

Ready to gas up? This set of 139 pieces gives kids enough to build a little filling station, two cute cars, and a squeegee for washing visiting windshields. A mini figure comes too, so cars aren't left high and dry when it's time to pump fuel. Plenty to keep small builders occupied, we love that the set meshes with themes in the LEGO city line, so it fits nicely in any imaginary town your kid may already have assembled on the bedroom floor. And like all LEGO, it inspires kids to follow visual directions and think spatially, while working fine motor skills and building hand muscles for the more complex writing that comes in first grade.
