Okay kiddo, a 10-minute walk means that you walk outside for 10 minutes straight. It's like when we walk to the park or to school. When we walk for 10 minutes, it means we keep moving our legs and feet for that much time. It's a good way to get some exercise and to stay healthy. Some people like to walk faster, and some like to take it slow, but the important thing is to keep going for the whole 10 minutes. Remember to wear comfortable shoes and bring water with you if it's hot outside. Have fun walking!
