From start to finish, a day in Bolt’s Russell Elementary classroom could be a primer on what high-quality preschool is supposed to look like. Children had free time to play with friends in a stimulating environment, received literacy instruction that pushed beyond comprehension to critical thinking and communication, and were introduced to complex mathematics concepts in age-appropriate ways. All three practices have been shown to go beyond increasing what children know to actually improving how well they learn in kindergarten and beyond.
