Math workbook is an important tool for students to consolidate and apply math knowledge, but it may not be possible to fully understand and master math concepts and problem-solving methods only by relying on the workbook itself. Teachers' explanations can provide more in-depth explanations and demonstrations to help students understand the essence and application methods of mathematical concepts. Teachers can answer students' questions in practice, correct their mistakes, and provide extra exercises and challenges to help students improve their math ability.
