Hi Kayla, I suspect you are struggling with walks for a good reason!
In my toddler trainings I ask teachers if they have ever observed toddlers walking of their own free will? Picture a toddler, they always run! (Or stumble, or creep)
Toddlers are working hard on developing two lesser-known senses. Body Awareness, (proprioception system) which is the sensation of the muscles and joints that enables the brain to know where each part of the body is and how it is moving, and Movement, (vestibular system) which contributes to our balance and our sense of where our body is in space.
It is critical to develop these senses early in order to feel comfortable in ones own body. Toddlers can seem very clumsy as these skills are in the early stages of development. It is important for them to have a safe, but challenging environment in which to practice all the kinds of movement that lead to mastery.
Another issue about walking from point A to point B with toddlers is that they are generally not interested in doing so. They live in the moment, and "here" is the best place to be, not "there." They can really enjoy a very small range and find meaning in small details, like cracks in sidewalks, rain running down a gutter, pipes coming out of a building or machinery working on the street.
Is there is a safe way to take the children out into the neighborhood, very close to your center, and let them experience the community by milling around, talking, and playing? I think you will find this a richer experience and there will be plenty of chances for teachers to observe what fascinates the students and follow up on these experiences in the classroom and yard.
