What is “Walk to school”?

Now we are working on a program of “walk to school”. We would like as many parents and children as possible to take part, even if in a small way. Children who walk to and from school along with their parents can learn essential(基本的) road safety and life skills.

You can take part by…

● Walking to and from school with your child every day.

● Walking for one or two days during the week.

● Encouraging others to walk, if you have already done.

Walking is great!

● You won’t have to waste time looking for a parking site(停车点).

● It’s free. You’ll save money by not using the car.

● It’s pollution free.

● It’s a good chance to your children and to meet other parents, too.

Enjoying walking to school!

Here are some suggestions to help you and your child enjoy walking to school.
