With adaptive learning, the programs won't move on to the next level until your child has a firm grasp on the current material. The online games will be a wonderful way for your child to catch up on basic arithmetic concepts and be comfortable using them across applications.
Teaching reading and other language arts skills to preschool learners relies heavily on a concept known as modeling. Modeling merely means exposing young children to the types of behaviors and habits we want them to learn. Many parents and homeschooling educators employ this kind of instruction naturally, without giving it much thought.
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.
Look for games and puzzles that are part of an adaptive learning program. This means that the online games are well-thought out and match the same set of skills that are being taught in the third grade curriculum. The program is structured toward each individual student and fills in the gaps where the child is struggling.
