Assess what your student already knows for each lesson that you teach. Know what the next steps should be in that student's learning and plan accordingly. Be flexible and do not make assumptions; being gifted in one subject does not mean that a particular student will be advanced in all areas or in all topics of that subject. Include details of the level of your gifted student in your lesson plan.
Allocate support. Do not restrict your own support or the support of other adults in your class to students who need extra help. Provide assistance for gifted students as well. Use peer support and group work, allowing your gifted student to work collaboratively with others, sharing his knowledge and ideas. Detail this support in your lesson plan.
Plan resources. Consider allowing your gifted student to use the Internet and software to research independently if the subject allows. Use more detailed books to extend her knowledge further. Specify the resources that will be available in your lesson plan.
Make sure that the task you set your gifted student is appropriate to his ability. Set an activity that will ensure he can achieve the learning objective for the lesson. Extend the learning objective to meet his ability. For example, if teaching sentence types, have middle-ability students make complex sentences by placing conjunctions in the middle of clauses and have your gifted students also construct complex sentences with a conjunction at the beginning. Detail this on your lesson plan.
Assess your student's progress against the learning objective so that you can then plan her next steps in learning. Use peer assessment and self-assessment in addition to your own grading. Include assessments in your lesson plan.
