Keep preschool writing activities relaxed and fun. Don't expect or require perfection. Learning to write is a fun process that will give your preschooler a boost in confidence and solid foundation for future studies.
Reading instruction is a component of the language arts curriculum that should be introduced across multiple subject matter content. Children ultimately have to understand what they read in a variety of textbooks, not just as part of a language arts class. Yet, reading instruction begins long before formal education begins, especially for homeschooling parents and educators.
The same children can play the games but in different ways, since the programs are tailored toward the learning styles of each child. This is what makes adaptive learning an essential tool in classrooms as well.
Worksheets also, when used properly, provide both the students and parent / tutor immediate feedback as to the child's progress. This means they can be used to point out areas where the student needs further reinforcement.
