33. Encourage your child to keep a Math notebook to copy examples which can then be revised at home. Draw models and label correctly. Before attempting the exam paper, get your child to read the questions first. Tick against questions that they have confidence in attempting. Attempt those first. Re-attempt the paper once they have completed to check that the answers tally. Highlight important information, and break it down. Label the workings wherever possible.
