At this age, you should show interest in, and explore, your environment. At first, your actions are random; for example, when you accidentally touch the mobile over your crib. Eventually, your actions should become deliberate and purposeful, as when you shake noisemaking toys like a bell or rattle. You should begin to recognize, and then anticipate, routine situations and events, as when you grin with expectation at the sight of your stroller. You should also recognize and gradually attach meaning to everyday sounds, as when you hear the telephone or your name. Eventually, you should recognize and respond to familiar words, including family names and what your favorite toys and activities are called.

At this age, you are learning about the world around you. When you play, you should learn how objects go together in different ways. You should learn that by pretending, your actions can represent real things. This helps you understand that words represent things, and that words are simply symbols or names for toys, people, places, and activities. You should refer to yourself and things around you by pointing and eventually by naming. You should form concepts and solve simple problems through purposeful experimentation (e.g., taking toys apart), imitation, constructive play (e.g., building with blocks), and pretend play activities. You should begin to respond to increasingly complex instructions and questions, and to produce an increasing number of words and grammatically correct simple sentences and questions.

When you are old enough to go to preschool or kindergarten, you should begin to learn and use the skills that will help you to read and write and do arithmetic when you are older. For example, listening to stories, rhyming words, and matching letters are skills needed for learning to read. Counting, sorting shapes, and building with blocks are skills needed to learn math. Painting, coloring, copying shapes, and using scissors are some of the skills needed in learning to write. Using words to ask questions, give answers, follow directions, describe things, explain what you mean, and tell stories allows you to acquire and share knowledge and experience of the world around you. All of these are called "readiness skills," and you should have them by the time you begin first grade.

When you are old enough to go to elementary and middle school, you should be able to learn to read, write, and do math, and discuss history and science. You will need to use these skills in academic situations to demonstrate what you have learned; e.g., by reading about various subjects and producing oral and written projects, solving mathematical problems, taking achievement tests, doing group work, and entering into class discussions. You will also need to use these skills in daily living situations at home and in the community (e.g., reading street signs, telling time, and making change). You should be able to use increasingly complex language (vocabulary and grammar) to share information and ideas with individuals or groups, by asking questions and expressing your own ideas, and by understanding and responding to the opinions of others.

In middle and high school, you should continue to demonstrate what you have learned in academic assignments (e.g., composition, classroom discussion, and laboratory experiments). You should also be able to use what you have learned in daily living situations without assistance (e.g., going to the store, using the library, and using public transportation). You should be able to comprehend and express both simple and complex ideas, using increasingly complex language (vocabulary and grammar) in learning and daily living situations (e.g., to obtain and convey information and ideas). You should also learn to apply these skills in practical ways that will help you enter the workplace after you finish school (e.g., carrying out instructions, preparing a job application, or being interviewed by a potential employer).
