These lists cover school milestones from the first day of preschool to graduation. If you have young children, start with the Preschool Supply List and the Kindergarten Supply List. Both come from real school lists, and the preschool one opens with the backpack. Check your own school's list before you buy, since lists differ from school to school. The 5th Grade School Supply List compares two lists that open differently, so confirm what your teacher wants before you shop. The Kindergarten Readiness Checklist sorts 25 points into five areas: social-emotional, language, early literacy, math and self-care. Use the Graduation Checklist to plan the end of the year, and mail party invitations about three weeks ahead.
