Your child should do their own work.
We know that as a parent you'll want to help your child any time they have difficulty and we obviously encourage this. However, it is important for your child to complete and master content with their own effort. Too much help can make it difficult for them to learn other concepts later.
We recommend to help your child when needed, in Lesson Instruction or Lesson Practice. This is when they are learning new concepts and practicing to build mastery. Note the blue background in the images below:
We recommend not helping your child during tests. Note the green background below, which is seen during Challenge and Mastery Tests.
Both Challenge and Mastery tests are there to ensure your child knows the concepts. For maximum program effectiveness, the activity should reflect the effort of your child alone.
